[0001] This application claims the benefit of and priority to U.S. Provisional Application No. 63 / 718,954, titled “MULTI-PORT FLUID SELECTION VALVE”, filed November 11, 2024, the contents of which are incorporated by reference herein.TECHNICAL FIELD

[0002] The present invention relates to fluidic selection valves generally, and more particularly to multiple port fluidic shear valves used in multiple fluid stream sample preparations for downstream analysis.BACKGROUND

[0003] Selector valves have been widely implemented for various fluidics applications to selectively direct fluid among a plurality of flow paths. An example application of multiple fluid process streams is in sample preparation systems that require more than one sample processing method prior to analysis, wherein example analysis modalities include liquid chromatography, mass spectrometry, optical sensors, and the like. Some applications utilize multiple chromatographic columns, wherein sample fluid flow may be selectively directed to and among a plurality of separation columns to effect the desired overall chromatographic separation.

[0004] A particular need for multiple channel selector valves arises in applications requiring multiple simultaneous flow streams. For instance, sample preparation systems may involve two or more input fluid streams to be directed to at least two separate output fluid streams, and in some cases at least two outputs among three or more output options. It is therefore an object to provide a system that is capable of handling at least two simultaneous input flow streams for processing to at least three output flow streams with as few distinct components as possible. It is further an object that such a system utilizes a multiple port shear valve.SUMMARY

[0028] FIG. 1 illustrates a comparison multiple flow stream management system with multiple selection valves. To accommodate systems with multiple simultaneous flow streams, a conventional approach utilizes multiple valves fluidically linked together. An example comparison system is schematically illustrated in FIG.l, wherein a first multiple port valve 10 is fluidically interconnected with a second multiple port valve 20 via an interconnection 30. First valve 10 accommodates four distinct input fluid streams (12, 14, 16, 18) at respective input ports (2, 4, 6, 8). A first rotor transfer groove 11 of first valve 10 may sequentially fluidically connectone of input ports 2, 4, 6, 8 to outlet port 19 by rotating the rotor of first valve 10 into the corresponding appropriate orientations. Outlet port 19 of first valve 10 is fluidically connected to inlet port 29 of second valve 20 through interconnection 30. Second valve 20 accommodates four distinct output fluid streams (22, 24, 26, 28) at respective output ports (32, 34, 38, 36). A second rotor transfer groove 21 of second valve 20 may sequentially fluidically connect one of output ports 32, 34, 36, 38 to inlet port 29 by rotating the rotor of second valve 20 into the corresponding appropriate orientations. Through the dual-valve mechanism schematically illustrated in FIG. 1, any input fluid stream 12, 14, 16, 18 may be directed through any output fluid stream 22, 24, 26, 28. However, this selection mechanism permits only a single flow selection at any given time, while the remaining input fluid streams must be in a “stop flow” condition. This eliminates the potential for continuous processing for multiple input fluid streams.

[0029] FIG. 2 illustrates another comparison multiple flow stream management system with multiple selection valves. In order to accommodate simultaneous flow between a selection of multiple input fluid streams and output fluid streams, conventional approaches require a complex array of valves and flow splitters and combiners. An example of such an approach is schematically illustrated in FIG. 2, which involves a first multiple port valve 110 (including outlet port 119) fluidically interconnected with a second multiple port valve 120 via an interconnection 130, as described above with reference to FIG. 1, as well as a third multiple port valve 140 (having outlet port 149) fluidically interconnected with a fourth multiple port valve 150 via an interconnection 160. First flow splitters 172, 174, 176, 178 split respective input flow streams 112, 114, 116, 118 into first split inlet flows 112a, 114a, 116a, 118a and second split inlet flows 112b, 114b, 116b, 118b. The rotor grooves 111, 141 of first and third valves 110, 140 may be independently operated to permit two distinct input streams to simultaneously be processed via interconnections 130, 160 through second and fourth valves 120, 150 to any output fluid stream 122, 124, 126, 128. As illustrated, output flows 122b, 124b, 126b, 128b from fourth valve 150 may be combined at flow combiners 182, 184, 186, 188 with output flows 122a, 124a, 126a, 128a from second valve 120 to establish output fluid stream 122, 124, 126, 128.

[0030] Systems such as that described with reference to FIG. 2 not only are complex involving several different components, they are also prone to undesirable results due to issues with cross-contamination between flow streams and band-spreading. Such systems are also notamenable to air segmented flow designs. Moreover, the system illustrated in FIG. 2 is limited to only two simultaneous flows.

[0031] Fluid selection valves as described herein include a stator fixedly secured to the valve body, and a rotor that is arranged in the valve for rotation by a valve shaft that can be driven by a motor. The relationships and general functionalities of the component parts of the fluid selection valves are described in U.S. Patent No. 9,739,383, assigned to the present applicant, and incorporated herein by reference. In one example, a difference in the fluid selection valves of the present invention from those described in U.S. Patent No. 9,739,383 is the structure of the dynamic face of the rotor, and its relationship with the fluidic ports at the stator dynamic face.

[0032] FIG. 3 illustrates fluid selection valve 300 of the present disclosure in a first position, according to some embodiments. FIG. 3 illustrates a superimposition of the grooves of the rotor dynamic face with the fluidic ports at the stator dynamic face. Fluid selection valve 300 includes a stator and a rotor, which can be rotated by a drive shaft of a motor assembly.The stator and the rotor of fluid selection valve 300 are both generally disk-shaped, and coaxially aligned together along the common longitudinal axis, valve axis 302, of the valve assembly. The rotor is configured to rotate about the longitudinal axis while the stator is fixed. In some embodiments, the rotor is positioned with the rotor dynamic face in juxtaposition with the stator dynamic face, and the rotor is rotatable with respect to the stator about the valve axis 302. An opposed side of the rotor is operably coupled to a valve driver, such as a drive shaft and motor assembly, for selective rotational movement about the longitudinal axis. The rotor may be rotated about the longitudinal axis in either a clockwise or counterclockwise direction, relative to the stator, to a selected position.

[0033] Fluid selection valve 300 illustrated in FIG. 3 is a 6-port configuration. Fluid selection valve 300 can be orientatable in three rotor positions that enable three simultaneous input streams processed to three outlet ports without flow interruption. The grooves in the rotor dynamic face fluidically connect respective fluid ports at the stator dynamic face. While the interfacing rotor face of the rotor, and the opposed stator face of the stator, are preferably substantially planar, they need not be as long as the two surfaces sufficiently mesh and mate in a fluid-tight manner while permitting relative rotational movement about the longitudinal axis between discrete positions.

[0034] In some embodiments, fluid selection valve 300 includes valve axis 302, stator dynamic face 310, first stator port 312, second stator port 314, third stator port 316, fourth stator port 318, fifth stator port 320, sixth stator port 322, first circumferential groove 330, second circumferential groove 332, cross-rotor groove 340, first inlet 350, second inlet 352, third inlet 354, first outlet 360, second outlet 362, and third outlet 364.

[0035] Valve axis 302 is a central longitudinal axis of the rotor and the stator. Stator dynamic face 310 is a face or surface of the stator arranged at the stator-rotor interface. In some embodiments, stator dynamic face 310 is a flat face of the stator. Stator dynamic face 310 includes a plurality of ports configured to permit fluid transfer therethrough. In some embodiments, stator dynamic face 310 includes a single ring (e.g., surrounding valve axis 302) of ports capable of permitting fluid transfer therethrough. Each of the stator ports can alternate being connected to an inlet stream and an outlet stream as the stator ports surround valve axis 302 in a single ring.

[0036] Fluid selection valve 300 includes stator ports. The stator ports are fluid transfer ports in stator dynamic face 310. In some embodiments, the stator ports include first stator port 312, second stator port 314, third stator port 316, fourth stator port 318, fifth stator port 320, and sixth stator port 322. Each of first stator port 312, second stator port 314, third stator port 316, fourth stator port 318, fifth stator port 320, and sixth stator port 322 can be fluidically connected to an input port, an output port, or alternatively, can be plugged. In some embodiments, each of first stator port 312, second stator port 314, third stator port 316, fourth stator port 318, fifth stator port 320, and sixth stator port 322 are fluidically connected to an input port or an output port. In some embodiments, fluid selection valve 300 includes eight or more stator ports. In some embodiments, fluid selection valve 300 includes ten or more stator ports. In some embodiments, at least one of first stator port 312, second stator port 314, third stator port 316, fourth stator port 318, fifth stator port 320, and sixth stator port 322, is plugged at an inlet port or outlet port of fluid selection valve 300.

[0037] The stator ports can be arranged at various radial distances from valve axis 302. In some embodiments, at least two stator ports are arranged at distinct radial distances from valve axis 302. In other embodiments, the stator ports can be arranged circumaxially about valve axis 302 in a spaced-apart pattern. In some embodiments, the stator ports are arranged circumaxially about valve axis 302 in a spaced-apart pattern defining circumferentially adjacent stator portsthat have no intervening stator port between them along a path 377 around valve axis 302. Circumaxially arranged stator ports can each be arranged at the same radial distance from valve axis 302. In some embodiments, the stator ports are substantially circular ports. In other embodiments, the stator ports can be independently selected from oval ports, rectangular ports, square ports, triangular ports, and polygonal ports.

[0038] The rotor of fluid selection valve 300 includes first circumferential groove 330. First circumferential groove 330 is configured to fluidically couple or bridge stator ports. By aligning an opening on one end of first circumferential groove 330 with a stator port and aligning an opening on the other end of first circumferential groove 330 with a different stator port, fluid flow is permitted, via first circumferential groove 330 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of first circumferential groove 330 terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0039] In some embodiments, first circumferential groove 330 fluidically connects circumferentially adjacent stator ports. First circumferential groove 330 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of first circumferential groove 330 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0040] Although the illustrated embodiment shows a circumferential groove fluidically connecting two circumferentially adjacent stator ports, it is contemplated that other port connection arrangements may be accomplished by the selection valves of the present invention. For example, in some embodiments, a single circumferential groove may fluidically connect one or more stator ports, including, but not limited to, one stator port, two stator ports, and three stator ports. In some embodiments, the circumferential grooves may be arranged to fluidically connect circumferentially adjacent stator ports, which are two or more stator ports positioned generally along a circumferential ring about a rotational axis of the rotor without another stator port disposed between them along the circumferential ring.

[0041] The rotor of fluid selection valve 300 includes second circumferential groove 332. Second circumferential groove 332 is configured to fluidically couple or bridge stator ports. Byaligning an opening on one end of second circumferential groove 332 with a stator port and aligning an opening on the other end of second circumferential groove 332 with a different stator port, fluid flow is permitted, via second circumferential groove 332 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of second circumferential groove 332 terminates at a dead-end into the stator face, preventing fluid flow therethrough. In some embodiments, second circumferential groove 332 fluidically connects circumferentially adjacent stator ports.

[0042] In some embodiments, second circumferential groove 332 fluidically connects circumferentially adjacent stator ports. Second circumferential groove 332 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of second circumferential groove 332 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0043] The rotor of fluid selection valve 300 includes at least one cross-rotor groove, such as cross-rotor groove 340. Cross-rotor groove 340 is orientatable to fluidically connect stator ports that are non-circumferentially adjacent. By aligning an opening on one end of cross-rotor groove 340 with a stator port and aligning an opening on the other end of cross-rotor groove 340 with a different stator port, fluid flow is permitted, via cross-rotor groove 340 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of cross-rotor groove 340 terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0044] In some embodiments, cross-rotor groove 340 fluidically connects non- circumferentially adjacent stator ports. For example, the rotor is rotatable with respect to the stator about the valve axis 302, and cross-rotor groove 340 is rotationally orientatable to fluidically connect stator ports that are non-circumferentially adjacent. Cross-rotor groove 340 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening / port alignment. The diameter of cross-rotor groove 340 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm toabout 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm. Fluid selection valve 300 can include exactly one cross-rotor groove. Fluid selection valve 300 can include exactly two cross-rotor grooves. Fluid selection valve 300 can include two or more cross-rotor grooves.

[0045] By utilizing cross-rotor groove 340, each of the first inlet 350, second inlet 352, and third inlet 354 can be fluidically connected to each of first outlet 360, second outlet 362, and third outlet 364 in three rotatable positions of fluid selection valve 300. This enables continuous processing for multiple input fluid streams. Accordingly, three parallel fluid paths can be flowing from inlets to outlets in each of three discrete rotation positions of fluid selection valve 300. This promotes continuous processing for multiple input fluid streams, and can reduce the number of valve rotations to reach the desired output.

[0046] Fluid selection valve 300 can include one or more inlets. The inlets can be in fluid communication with at least one of the stator ports. In some embodiments, fluid selection valve 300 includes first inlet 350, second inlet 352, and third inlet 354. Each of the inlets can permit fluid transfer therethrough to a stator port. The fluid can be transferred using a pump and / or a fluid tank. In some embodiments, the one or more inlets are ports in at least a portion of the stator. In some embodiments, the one or more inlets include fluid transfer tubing. In some embodiments, the one or more inlets are fluid streams. In one example, first inlet 350 is in fluid communication with fourth stator port 318, second inlet 352 is in fluid communication with second stator port 314, and third inlet 354 is in fluid communication with sixth stator port 322. Fluid selection valve 300 can include two or more inlets. In one example, fluid selection valve 300 includes three or more inlets. Fluid selection valve 300 can have exactly two inlets. In one example, fluid selection valve 300 can have exactly three inlets.

[0047] Fluid selection valve 300 can include one or more outlets. The outlets can be in fluid communication with at least one of the stator ports. In some embodiments, fluid selection valve 300 includes first outlet 360, second outlet 362, and third outlet 364. Each of the outlets can permit fluid transfer therethrough. Each of the outlets can be in fluid communication with a downstream analysis unit or fluid storage tank. In some embodiments, the one or more outlets are ports in at least a portion of the stator. In some embodiments, the one or more outlets include fluid transfer tubing. In some embodiments, the one or more outlets are fluid streams. In one example, first outlet 360 is in fluid communication with first stator port 312, second outlet 362 isin fluid communication with third stator port 316, and third outlet 364 is in fluid communication with fifth stator port 320. Fluid selection valve 300 can include two or more outlets. In one example, fluid selection valve 300 includes three or more outlets. Fluid selection valve 300 can have exactly two outlets. In one example, fluid selection valve 300 can have exactly three outlets.

[0048] In some embodiments, cross-rotor groove 340 fluidically connects fourth stator port 318 to first stator port 312, sufficient for fluid transfer from first inlet 350 to first outlet 360, when fluid selection valve 300 is in a first position. In some embodiments, first circumferential groove 330 fluidically connects second stator port 314 to third stator port 316, sufficient for fluid transfer from second inlet 352 to second outlet 362, when fluid selection valve 300 is in the first position. In some embodiments, second circumferential groove 332 fluidically connects sixth stator port 322 to fifth stator port 320, sufficient for fluid transfer from third inlet 354 to third outlet 364, when fluid selection valve 300 is in the first position.

[0049] In some embodiments, cross-rotor groove 340 fluidically connects sixth stator port 322 to third stator port 316, sufficient for fluid transfer from third inlet 354 to second outlet 362, when fluid selection valve 300 is in a second position. In some embodiments, first circumferential groove 330 fluidically connects second stator port 314 to first stator port 312, sufficient for fluid transfer from second inlet 352 to first outlet 360, when fluid selection valve 300 is in the second position. In some embodiments, second circumferential groove 332 fluidically connects fourth stator port 318 to fifth stator port 320, sufficient for fluid transfer from first inlet 350 to third outlet 364, when fluid selection valve 300 is in the second position.

[0050] In some embodiments, cross-rotor groove 340 fluidically connects second stator port 314 to fifth stator port 320, sufficient for fluid transfer from second inlet 352 to third outlet 364, when fluid selection valve 300 is in a third position. In some embodiments, first circumferential groove 330 fluidically connects sixth stator port 322 to first stator port 312, sufficient for fluid transfer from third inlet 354 to first outlet 360, when fluid selection valve 300 is in the third position. In some embodiments, second circumferential groove 332 fluidically connects fourth stator port 318 to third stator port 316, sufficient for fluid transfer from first inlet 350 to second outlet 362, when fluid selection valve 300 is in the third position.

[0051] The rotor of fluid selection valve 300 is rotatable with respect to the stator about the valve axis 302. Accordingly, each of the first inlet 350, second inlet 352, and third inlet 354 canbe fluidically connected to each of first outlet 360, second outlet 362, and third outlet 364 in three rotatable positions of fluid selection valve 300. This enables continuous processing for multiple input fluid streams. In some embodiments, in each of the three positions, none of the first inlet 350, second inlet 352, and third inlet 354 are in a “stop-flow” condition.

[0052] FIG. 4 illustrates fluid selection valve 400 in a first position, according to some embodiments. FIG. 4 illustrates a superimposition of the grooves of the rotor dynamic face with the fluidic ports at the stator dynamic face. Fluid selection valve 400 includes a stator and a rotor, which can be rotated by a drive shaft of a motor assembly. The stator and the rotor of fluid selection valve 400 are both generally disk-shaped, and co-axially aligned together along the common longitudinal axis of the valve assembly. The rotor is configured to rotate about the longitudinal axis while the stator is fixed. In some embodiments, the rotor is positioned with the rotor dynamic face in juxtaposition with the stator dynamic face, and the rotor is rotatable with respect to the stator about the valve axis 402. An opposed side of the rotor is operably coupled to a valve driver, such as a drive shaft and motor assembly, for selective rotational movement about the longitudinal axis. The rotor may be rotated about the longitudinal axis in either a clockwise or counterclockwise direction, relative to the stator, to a selected position. Fluid selection valve 400 may additionally or alternatively include one or more features or configurations of fluid selection valve 300.

[0053] Fluid selection valve 400 illustrated in FIG. 3 is an 8-port configuration. Fluid selection valve 400 can be orientatable in multiple rotor positions (e.g., eight discrete positions) that enable four simultaneous input streams processed to four outlet ports without flow interruption. The grooves in the rotor dynamic face fluidically connect respective fluid ports at the stator dynamic face. While the interfacing rotor face of the rotor, and the opposed stator face of the stator, are preferably substantially planar, they need not be as long as the two surfaces sufficiently mesh and mate in a fluid-tight manner while permitting relative rotational movement about the longitudinal axis between discrete positions.

[0054] In some embodiments, fluid selection valve 400 includes valve axis 402, stator dynamic face 410, first stator port 412, second stator port 414, third stator port 416, fourth stator port 418, fifth stator port 420, sixth stator port 422, seventh stator port 424, eighth stator port 426, first circumferential groove 430, second circumferential groove 432, third circumferentialgroove 434, cross-rotor groove 440, first inlet 450, second inlet 452, third inlet 454, fourth inlet 456, first outlet 460, second outlet 462, third outlet 464, and fourth outlet 466.

[0055] Valve axis 402 is a central longitudinal axis of the rotor and the stator. Stator dynamic face 410 is a face or surface of the stator arranged at the stator-rotor interface. In some embodiments, stator dynamic face 410 is a flat face of the stator. Stator dynamic face 410 includes a plurality of ports configured to permit fluid transfer therethrough. In some embodiments, stator dynamic face 410 includes a single ring of ports (e.g., along a path like path 377) capable of permitting fluid transfer therethrough. Each of the stator ports can alternate being connected to an inlet stream and an outlet stream as the stator ports surround valve axis 402 in a single ring.

[0056] Fluid selection valve 400 includes stator ports. The stator ports are fluid transfer ports in stator dynamic face 410. In some embodiments, the stator ports include first stator port 412, second stator port 414, third stator port 416, fourth stator port 418, fifth stator port 420, sixth stator port 422, seventh stator port 424, and eighth stator port 426. Each of first stator port 412, second stator port 414, third stator port 416, fourth stator port 418, fifth stator port 420, sixth stator port 422, seventh stator port 424, and eighth stator port 426 can be fluidically connected to an input port, an output port, or alternatively, can be plugged. In some embodiments, and as shown in FIG. 4, fourth stator port 418 and seventh stator port 424 are non- circumferentially adjacent ports 478.

[0057] In some embodiments, each of first stator port 412, second stator port 414, third stator port 416, fourth stator port 418, fifth stator port 420, sixth stator port 422, seventh stator port 424, and eighth stator port 426 are fluidically connected to an input port or an output port. In some embodiments, fluid selection valve 400 includes eight or more stator ports. In some embodiments, fluid selection valve 400 includes ten or more stator ports. In some embodiments, at least one of first stator port 412, second stator port 414, third stator port 416, fourth stator port 418, fifth stator port 420, sixth stator port 422, seventh stator port 424, and eighth stator port 426, is plugged at an inlet port or outlet port of fluid selection valve 400.

[0058] The stator ports can be arranged at various radial distances from valve axis 402. In some embodiments, at least two stator ports are arranged at distinct radial distances from valve axis 402. In other embodiments, the stator ports can be arranged circumaxially about valve axis 402 in a spaced-apart pattern. In some embodiments, the stator ports are arranged circumaxiallyabout valve axis 402 in a spaced-apart pattern defining circumferentially adjacent stator ports that have no intervening stator port between them along a path around valve axis 402.Circumaxially arranged stator ports can each be arranged at the same radial distance from valve axis 402. In some embodiments, the stator ports are substantially circular ports. In other embodiments, the stator ports can be independently selected from oval ports, rectangular ports, square ports, triangular ports, and polygonal ports.

[0059] The rotor of fluid selection valve 400 includes first circumferential groove 430. First circumferential groove 430 is configured to fluidically couple or bridge stator ports. By aligning an opening on one end of first circumferential groove 430 with a stator port and aligning an opening on the other end of first circumferential groove 430 with a different stator port, fluid flow is permitted, via first circumferential groove 430 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of first circumferential groove 430 terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0060] In some embodiments, first circumferential groove 430 fluidically connects circumferentially adjacent stator ports. First circumferential groove 430 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of first circumferential groove 430 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0061] The rotor of fluid selection valve 400 includes second circumferential groove 432. Second circumferential groove 432 is configured to fluidically couple or bridge stator ports. By aligning an opening on one end of second circumferential groove 432 with a stator port and aligning an opening on the other end of second circumferential groove 432 with a different stator port, fluid flow is permitted, via second circumferential groove 432 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of second circumferential groove 432 terminates at a dead-end into the stator face, preventing fluid flow therethrough. In someembodiments, second circumferential groove 432 fluidically connects circumferentially adjacent stator ports.

[0062] In some embodiments, second circumferential groove 432 fluidically connects circumferentially adjacent stator ports. Second circumferential groove 432 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of second circumferential groove 432 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0063] The rotor of fluid selection valve 400 includes third circumferential groove 434. Third circumferential groove 434 is configured to fluidically couple or bridge stator ports. By aligning an opening on one end of third circumferential groove 434 with a stator port and aligning an opening on the other end of third circumferential groove 434 with a different stator port, fluid flow is permitted, via third circumferential groove 434 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of third circumferential groove 434 terminates at a dead-end into the stator face, preventing fluid flow therethrough. In some embodiments, third circumferential groove 434 fluidically connects circumferentially adjacent stator ports.

[0064] In some embodiments, third circumferential groove 434 fluidically connects circumferentially adjacent stator ports. Third circumferential groove 434 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of third circumferential groove 434 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0065] The rotor of fluid selection valve 400 includes cross-rotor groove 440. Cross-rotor groove 440 is orientatable to fluidically connect stator ports that are non-circumferentially adjacent (e.g., non-circumferentially adjacent ports 478). By aligning an opening on one end of cross-rotor groove 440 with a stator port and aligning an opening on the other end of cross-rotor groove 440 with a different stator port, fluid flow is permitted, via cross-rotor groove 440 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidlydecoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of cross-rotor groove 440 terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0066] In some embodiments, cross-rotor groove 440 fluidically connects non- circumferentially adjacent stator ports. For example, the rotor is rotatable with respect to the stator about the valve axis 402, wherein cross-rotor groove 440 is rotationally orientatable to fluidically connect stator ports that are non-circumferentially adjacent. Cross-rotor groove 440 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening / port alignment. The diameter of cross-rotor groove 440 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0067] For example, by utilizing cross-rotor groove 440, each of the first inlet 450, second inlet 452, third inlet 454, and fourth inlet 456 can be fluidically connected to each of first outlet 460, second outlet 462, third outlet 464, and fourth outlet 466 in eight rotatable positions of fluid selection valve 400. This enables continuous processing for multiple input fluid streams. Accordingly, four parallel fluid paths can be flowing from inlets to outlets in discrete rotational positions of fluid selection valve 400. This promotes continuous processing for multiple input fluid streams.

[0068] Fluid selection valve 400 can include one or more inlets. The inlets can be in fluid communication with at least one of the stator ports. In some embodiments, the one or more inlets are ports in at least a portion of the stator. In some embodiments, the one or more inlets include fluid transfer tubing. In some embodiments, the one or more inlets are fluid streams. In some embodiments, fluid selection valve 400 includes first inlet 450, second inlet 452, third inlet 454, and fourth inlet 456. Each of the inlets can permit fluid transfer therethrough to a stator port. Fluid selection valve 400 can include one or more outlets. The outlets can be in fluid communication with at least one of the stator ports. In some embodiments, the one or more outlets are ports in at least a portion of the stator. In some embodiments, the one or more outlets include fluid transfer tubing. In some embodiments, the one or more outlets are fluid streams. In some embodiments, fluid selection valve 400 includes first outlet 460, second outlet 462, thirdoutlet 464, and fourth outlet 466. Each of the inlets can permit fluid transfer therethrough to a stator port.

[0069] It is to be understood that various multiple port selection valve arrangements are contemplated with various numbers of stator ports and rotor grooves to accomplish the flow simplification described above, wherein multiple flow streams may be simultaneously processed through a single selection valve without flow interruption.

[0070] FIG. 5A illustrates fluid selection valve 400 in the first position, according to some embodiments. When fluid selection valve 400 is in the first position 510, cross-rotor groove 440 fluidically connects fourth stator port 418 to seventh stator port 424, fluidically connecting third inlet 454 to third outlet 464. When fluid selection valve 400 is in the first position 510, first circumferential groove 430 fluidically connects second stator port 414 to third stator port 416, fluidically connecting second inlet 452 to second outlet 462. When fluid selection valve 400 is in the first position 510, second circumferential groove 432 fluidically connects fifth stator port 420 to sixth stator port 422, fluidically connecting fourth inlet 456 to fourth outlet 466. When fluid selection valve 400 is in the first position 510, third circumferential groove 434 fluidically connects first stator port 412 to eighth stator port 426, fluidically connecting first inlet 450 to first outlet 460.

[0071] FIG. 5B illustrates fluid selection valve 400 in a second position 520, according to some embodiments. FIG. 5C illustrates fluid selection valve 400 in a third position 530, according to some embodiments. FIG. 5D illustrates fluid selection valve 400 in a fourth position 540, according to some embodiments. FIG. 5E illustrates fluid selection valve 400 in a fifth position 550, according to some embodiments. FIG. 5F illustrates fluid selection valve 400 in a sixth position 560, according to some embodiments. FIG. 5G illustrates fluid selection valve 400 in a seventh position 570, according to some embodiments. FIG. 5H illustrates fluid selection valve 400 in an eighth position 580, according to some embodiments. Table 1 provides the fluidic connections between inlets and outlets for each of the eight positions illustrated in FIGS. 5A-5HTable 1. Fluid Selection Valve 400 Fluidic Connections.

[0072] As shown, each rotational position change causes the circumferential grooves and the cross-rotor groove to fluidically connect different sets of stator inlet ports to stator outlet ports. Such a configuration can allow for four input streams to be fluidically connected to any of four output ports, with each input being connected to a single output at each rotor position. While a given input / output port pair may be duplicated over the eight total positions, there is no position at which input flow is blocked. This allows for simultaneous flow from multiple inputs to multiple outputs. Alternatively, fluid selection valve 400 may be used to control a plurality of input streams to a plurality of connected outputs when simultaneous flow from all inputs is not required. It is to be understood that not all of the stator ports must be used in any given application. For example, fluid selection valve 400 may be configured for a two-input, three- output application using five of the eight available inlet / outlet stator ports, and plugging the remaining stator ports.

[0073] FIG. 6A illustrates fluid selection valve 400 in the first position with two input streams and two output streams, shown as configuration 610, according to some embodiments. FIG. 6B illustrates fluid selection valve 400 in the second position with two input streams and two output streams, shown as configuration 620, according to some embodiments. FIG. 6C illustrates fluid selection valve 400 in the fifth position with two input streams and two output streams, shown as configuration 630, according to some embodiments. FIG. 6D illustrates fluid selection valve 400 in the sixth position with two input streams and two output streams, shownas configuration 640, according to some embodiments. Table 2 provides the fluidic connections between inlets and outlets for each of the positions shown in FIGS. 6A-6D.Table 2. Fluid Selection Valve 400 Fluidic Connections.

[0074] FIG. 7 illustrates fluid selection valve 700, according to some embodiments. FIG. 7 illustrates a superimposition of the grooves of the rotor dynamic face with the fluidic ports at the stator dynamic face. Fluid selection valve 700 includes a stator and a rotor, which can be rotated by a drive shaft of a motor assembly. The stator and the rotor of fluid selection valve 700 are both generally disk-shaped, and co-axially aligned together along the common longitudinal axis of the valve assembly. The rotor is configured to rotate about the longitudinal axis while the stator is fixed. In some embodiments, the rotor is positioned with the rotor dynamic face in juxtaposition with the stator dynamic face, and the rotor is rotatable with respect to the stator about the valve axis 702. An opposed side of the rotor is operably coupled to a valve driver, such as a drive shaft and motor assembly, for selective rotational movement about the longitudinal axis. The rotor may be rotated about the longitudinal axis in either a clockwise or counterclockwise direction, relative to the stator, to a selected position. Fluid selection valve 700 may additionally or alternatively include one or more features or configurations of fluid selection valve 400.

[0075] Fluid selection valve 700 illustrated in FIG. 7 is a 8-port configuration. Fluid selection valve 700 can be orientatable in four rotor positions that enable four simultaneous input streams processed to four outlet ports without flow interruption. The grooves in the rotor dynamic face fluidically connect respective fluid ports at the stator dynamic face. While the interfacing rotor face of the rotor, and the opposed stator face of the stator, are preferablysubstantially planar, they need not be as long as the two surfaces sufficiently mesh and mate in a fluid-tight manner while permitting relative rotational movement about the longitudinal axis between discrete positions.

[0076] In some embodiments, fluid selection valve 700 includes valve axis 702, stator dynamic face 710, first stator port 712, second stator port 714, third stator port 716, fourth stator port 718, fifth stator port 720, sixth stator port 722, seventh stator port 724, eighth stator port 726, first circumferential groove 730, second circumferential groove 732, first cross-rotor groove 740, second cross-rotor groove 742, first inlet 750, second inlet 752, third inlet 754, fourth inlet 756, first outlet 760, second outlet 762, third outlet 764, and fourth outlet 766.

[0077] Valve axis 702 is a central longitudinal axis of the rotor and the stator. Stator dynamic face 710 is a face or surface of the stator arranged at the stator-rotor interface. In some embodiments, stator dynamic face 710 is a flat face of the stator. Stator dynamic face 710 includes a plurality of ports configured to permit fluid transfer therethrough. In some embodiments, stator dynamic face 710 includes a single ring of ports (e.g., along a path like path 377) capable of permitting fluid transfer therethrough. Each of the stator ports can alternate being connected to an inlet stream and an outlet stream as the stator ports surround valve axis 702 in a single ring.

[0078] Fluid selection valve 700 includes stator ports. The stator ports are fluid transfer ports in stator dynamic face 710. In some embodiments, the stator ports include first stator port 712, second stator port 714, third stator port 716, fourth stator port 718, fifth stator port 720, sixth stator port 722, seventh stator port 724, and eighth stator port 726. Each of first stator port 712, second stator port 714, third stator port 716, fourth stator port 718, fifth stator port 720, sixth stator port 722, seventh stator port 724, and eighth stator port 726 can be fluidically connected to an input port, an output port, or alternatively, can be plugged.

[0079] In some embodiments, each of first stator port 712, second stator port 714, third stator port 716, fourth stator port 718, fifth stator port 720, sixth stator port 722, seventh stator port 724, and eighth stator port 726 are fluidically connected to an input port or an output port. In some embodiments, fluid selection valve 700 includes eight or more stator ports. In some embodiments, fluid selection valve 700 includes ten or more stator ports. In some embodiments, at least one of first stator port 712, second stator port 714, third stator port 716, fourth stator port 718, fifth stator port 720, sixth stator port 722, seventh stator port 724, and eighth stator port 726,is plugged at an inlet port or outlet port of fluid selection valve 700. In some embodiments, and as shown in FIG. 7, second stator port 714 and third stator port 716 are circumferentially adjacent ports 779.

[0080] The stator ports can be arranged at various radial distances from valve axis 702. In some embodiments, at least two stator ports are arranged at distinct radial distances from valve axis 702. The stator ports can be arranged circumaxially about valve axis 702 in a spaced-apart pattern. In some embodiments, the stator ports are equally spaced and arranged along the path about the valve axis 702. In some embodiments, the stator ports are arranged circumaxially about valve axis 702 in a spaced-apart pattern defining circumferentially adjacent stator ports that have no intervening stator port between them along a path around valve axis 702. Circumaxially arranged stator ports can each be arranged at the same radial distance from valve axis 702. In some embodiments, the stator ports are substantially circular ports. In other embodiments, the stator ports can be independently selected from oval ports, rectangular ports, square ports, triangular ports, and polygonal ports.

[0081] The rotor of fluid selection valve 700 includes first circumferential groove 730. First circumferential groove 730 is configured to fluidically couple or bridge stator ports. By aligning an opening on one end of first circumferential groove 730 with a stator port and aligning an opening on the other end of first circumferential groove 730 with a different stator port, fluid flow is permitted, via first circumferential groove 730 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of first circumferential groove 730 terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0082] In some embodiments, first circumferential groove 730 fluidically connects circumferentially adjacent stator ports (e.g., circumferentially adjacent ports 779). First circumferential groove 730 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of first circumferential groove 730 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0083] The rotor of fluid selection valve 700 includes second circumferential groove 732. Second circumferential groove 732 is configured to fluidically couple or bridge stator ports. By aligning an opening on one end of second circumferential groove 732 with a stator port and aligning an opening on the other end of second circumferential groove 732 with a different stator port, fluid flow is permitted, via second circumferential groove 732 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of second circumferential groove 732 terminates at a dead-end into the stator face, preventing fluid flow therethrough. In some embodiments, second circumferential groove 732 fluidically connects circumferentially adjacent stator ports.

[0084] In some embodiments, second circumferential groove 732 fluidically connects circumferentially adjacent stator ports. Second circumferential groove 732 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening alignment. The diameter of second circumferential groove 732 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0085] The rotor of fluid selection valve 700 includes first cross-rotor groove 740. First cross-rotor groove 740 is orientatable to fluidically connect stator ports that are non- circumferentially adjacent. By aligning an opening on one end of first cross-rotor groove 740 with a stator port and aligning an opening on the other end of first cross-rotor groove 740 with a different stator port, fluid flow is permitted, via first cross-rotor groove 740 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of first cross-rotor groove 740 terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0086] In some embodiments, first cross-rotor groove 740 fluidically connects non- circumferentially adjacent stator ports. For example, the rotor is rotatable with respect to the stator about the valve axis 702, wherein the first cross-rotor groove 740 is rotationally orientatable to fluidically connect stator ports that are non-circumferentially adjacent. First crossrotor groove 740 can be sized to accommodate sufficient fluid flow therethrough, and tofacilitate opening / port alignment. The diameter of first cross-rotor groove 740 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0087] Compared to fluid selection valve 400, the rotor of fluid selection valve 700 includes second cross-rotor groove 742. Second cross-rotor groove 742 is orientatable to fluidically connect stator ports that are non-circumferentially adjacent. By aligning an opening on one end of second cross-rotor groove 742 with a stator port and aligning an opening on the other end of second cross-rotor groove 742 with a different stator port, fluid flow is permitted, via second cross-rotor groove 742 of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. In some embodiments, when the openings are not aligned, at least one end of second cross-rotor groove 742 terminates at a deadend into the stator face, preventing fluid flow therethrough. The second cross-rotor groove 742 can be arranged substantially parallel to first cross-rotor groove 740.

[0088] In some embodiments, second cross-rotor groove 742 fluidically connects non- circumferentially adjacent stator ports. For example, the rotor is rotatable with respect to the stator about the valve axis 702, wherein the second cross-rotor groove 742 is rotationally orientatable to fluidically connect stator ports that are non-circumferentially adjacent. Second cross-rotor groove 742 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening / port alignment. The diameter of second cross-rotor groove 742 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0089] Use of second cross-rotor groove 742 promotes more efficient valve operation and rotation, due at least to less rotations required to rotate through all inlet and outlet combinations. This allows for the ability of fluid selection valve 700 to connect any of the inputs to any of the outputs while reducing or preventing movements and / or repeat connections. For example, fluid selection valve 700 may be rotatable about valve axis 702 into eight discrete rotational positions that align grooves 730, 732, 740, 742 with respective stator ports. However, the presence of cross-rotor grooves 740, 742 permits all four inputs to be connected to a distinct output,promoting parallel fluid paths, in only four discrete rotational positions (Table 3). For example, by rotating fluid selection valve 700 from a first position to a second position, from the second position to a third position, and from the third position to a fourth position (e g., with only three discrete rotational movements from the first position), each input of fluid selection valve 700 can be fluidically connected to each outlet, without repetition. In one non-limiting example, compared to fluid selection valve 400 having one cross-rotor groove 440 and rotationally connecting four inputs to four outputs with eight rotations (e.g., with some repeated connections), fluid selection valve 700 including first cross-rotor groove 740 and second crossrotor groove 742 is capable of each of four inputs being fluidically connected to each of four outputs, promoting parallel fluid paths, in just four discrete rotational positions.

[0090] Table 3 below sets forth each of four rotational positions in which each of the inlets (750, 752, 754, 756) may be fluidically connected to a respective one of the outlets (760, 762, 764, 766) without any duplication. As a result, movements of fluid selection valve may be minimized while nevertheless enabling full functionality of an 8-port valve with as many as four distinct inlets and four distinct outlets.Table 3. Fluid Selection Valve 700 Fluidic Connections.

[0091] Fluid selection valve 700 can include one or more inlets. The inlets can be in fluid communication with at least one of the stator ports. In some embodiments, fluid selection valve 700 includes at least three inlet ports or at least four inlet ports. In some embodiments, the one or more inlets are ports in at least a portion of the stator. In some embodiments, the one or more inlets include fluid transfer tubing. In some embodiments, the one or more inlets are fluid streams. In some embodiments, fluid selection valve 700 includes first inlet 750, second inlet752, third inlet 754, and fourth inlet 756. Each of the inlets can permit fluid transfer therethrough to a stator port. Fluid selection valve 700 can include one or more outlets. The outlets can be in fluid communication with at least one of the stator ports. Tn some embodiments, the one or more outlets are ports in at least a portion of the stator. In some embodiments, the one or more outlets include fluid transfer tubing. In some embodiments, the one or more outlets are fluid streams. In some embodiments, fluid selection valve 700 includes at least three outlet ports or at least four outlet ports. In some embodiments, fluid selection valve 700 includes first outlet 760, second outlet 762, third outlet 764, and fourth outlet 766. Each of the inlets can permit fluid transfer therethrough to a stator port.

[0092] In some embodiments, fluid selection valve 700 includes at least three inlet ports and at least three outlet ports, and the grooves (e.g., first circumferential groove 730, second circumferential groove 732, first cross-rotor groove 740, and second cross-rotor groove 742) are arranged such that in each of at least three discrete rotational positions of the rotor relative to the stator about the valve axis 702, the grooves define independent and non-intersecting flow paths each fluidically connecting a different one of the at least three inlet ports of fluid selection valve 700 to a different one of the at least three outlet ports. In some embodiments, none of the at least three inlet ports of the fluid selection valve are in a stop-flow condition in any of the at least three discrete positions.

[0093] In some embodiments, fluid selection valve 700 includes at least four inlet ports and at least four outlet ports, and the grooves (e.g., first circumferential groove 730, second circumferential groove 732, first cross-rotor groove 740, and second cross-rotor groove 742) are arranged such that in each of at least four discrete rotational positions of the rotor relative to the stator about the valve axis 702, the grooves define independent and non-intersecting flow paths each connecting a different one of the at least four inlet ports of the fluid selection valve 700 to a different one of the at least four outlet ports. In some embodiments, none of the at least four inlet ports of the fluid selection valve are in a stop-flow condition in any of the at least four discrete positions.

[0094] FIG. 8 illustrates fluid selection valve 800, according to some embodiments. FIG. 8 illustrates a superimposition of the grooves of the rotor dynamic face with the fluidic ports at the stator dynamic face. Fluid selection valve 800 includes a stator and a rotor, which can be rotated by a drive shaft of a motor assembly. The stator and the rotor of fluid selection valve800 are both generally disk-shaped, and co-axially aligned together along the common longitudinal axis of the valve assembly. The rotor is configured to rotate about the longitudinal axis while the stator is fixed. In some embodiments, the rotor is positioned with the rotor dynamic face in juxtaposition with the stator dynamic face, and the rotor is rotatable with respect to the stator about the valve axis 802. An opposed side of the rotor is operably coupled to a valve driver, such as a drive shaft and motor assembly, for selective rotational movement about the longitudinal axis. The rotor may be rotated about the longitudinal axis in either a clockwise or counterclockwise direction, relative to the stator, to a selected position. Fluid selection valve 800 may additionally or alternatively include one or more features or configurations of fluid selection valve 700.

[0095] Fluid selection valve 800 illustrated in FIG. 8 is a 12-port configuration.

In someembodiments, stator dynamic face 810 includes a single ring of ports capable of permitting fluid transfer therethrough. Each of the stator ports can alternate being connected to an inlet stream and an outlet stream as the stator ports surround valve axis 802 in a single ring.

[0098] Fluid selection valve 800 includes stator ports. The stator ports are fluid transfer ports in stator dynamic face 810. In some embodiments, the stator ports include first stator port 812, second stator port 813, third stator port 814, fourth stator port 815, fifth stator port 816, sixth stator port 817, seventh stator port 818, eighth stator port 819, ninth stator port 820, tenth stator port 821, eleventh stator port 822, and twelfth stator port 823.

[0100] The stator ports can be arranged at various radial distances from valve axis 802. In some embodiments, at least two stator ports are arranged at distinct radial distances from valve axis 802. In some embodiments, the stator ports can be arranged circumaxially about valve axis 802 in a spaced-apart pattern.

First circumferential groove 830 and second circumferential groove 832 are each configured to fluidically couple or bridge stator ports. By aligning an opening on one end of the circumferential groove with a stator port and aligning an opening on the other end of the circumferential groove with a different stator port, fluid flow is permitted, via each of the circumferential grooves of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of the circumferential groove terminates at a dead-end into the stator face, preventing fluid flow therethrough.

[0102] In some embodiments, first circumferential groove 830 and second circumferential groove 832 each fluidically connect circumferentially adjacent stator ports.

[0103] The rotor of fluid selection valve 800 includes first cross-rotor groove 840, second cross-rotor groove 842, third cross-rotor groove 844, and fourth cross-rotor groove 846. Each of first cross-rotor groove 840, second cross-rotor groove 842, third cross-rotor groove 844, and fourth cross-rotor groove 846 are orientatable to fluidically connect stator ports that are non- circumferentially adjacent. By aligning an opening on one end of the cross-rotor groove with a stator port and aligning an opening on the other end of the cross-rotor groove with a different stator port, fluid flow is permitted, via the cross-rotor groove of the rotor, between two distinct stator ports. In contrast, the distinct stator ports can be fluidly decoupled from by rotating the rotor such that the openings on the rotor and the openings on the stator are not aligned. Thus, when the openings are not aligned, at least one end of a cross-rotor groove terminates at a deadend into the stator face, preventing fluid flow therethrough.

[0104] In some embodiments, each of first cross-rotor groove 840, second cross-rotor groove 842, third cross-rotor groove 844, and fourth cross-rotor groove 846 fluidically connect non-circumferentially adjacent stator ports. For example, the rotor is rotatable with respect to the stator about the valve axis 802, wherein first cross-rotor groove 840, second cross-rotor groove 842, third cross-rotor groove 844, and fourth cross-rotor groove 846 are rotationally orientatable to fluidically connect stator ports that are non-circumferentially adjacent. First cross-rotor groove 840, second cross-rotor groove 842, third cross-rotor groove 844, and fourth cross-rotor groove 846 can be sized to accommodate sufficient fluid flow therethrough, and to facilitate opening / port alignment. The diameter of first cross-rotor groove 840, second cross-rotor groove 842, third cross-rotor groove 844, and fourth cross-rotor groove 846 may be slightly oversized relative to the diameter of the stator ports to be aligned therewith, for instance, in the range of about 2.2 mm to about 0.12 mm when the stator ports have a diameter in the range of about 2.0 mm to about 0.10 mm.

[0105] In some embodiments, fluid selection valve 800 includes at least six inlet ports and at least six outlet ports, and the grooves are arranged such that in each of at least six discrete rotational positions of the rotor relative to the stator about the valve axis 802, the grooves define independent and non-intersecting flow paths each connecting a different one of the at least six inlet ports of the fluid selection valve 800 to a different one of the at least six outlet ports.
