Flow-Through Poppet for Valves and RegulatorsCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority7under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 63 / 756,063, filed February 8, 2025, the entire contents of which are incorporated herein by reference.FIELD OF INVENTION
[0002] The present disclosure relates to fluid control valves and regulators, and more particularly to a flow-through poppet configuration that enables increased fluid flow rates and provides flexibility7in port positioning within valve assemblies.BACKGROUND
[0003] Traditional fluid control valves and regulators commonly employ7poppet-type valve elements to control fluid flow between inlet and outlet ports. In conventional poppet valve designs, the poppet element typically includes a solid valve body that blocks or allows fluid flow by moving into and out of engagement with a valve seat. When the valve is actuated to an open position, fluid flows around the exterior of the poppet element, passing over the poppet body and through the available flow area between the poppet and the valve housing.
[0004] This conventional flow arrangement presents certain limitations in valve design and performance. The flow path geometry in traditional poppet valves can restrict the achievable flow rates for a given valve size, as the fluid must navigate around the poppet body rather than through more direct flow passages, and thus flow rate is limited by the stroke of the poppet. Additionally, the requirement for fluid to flow over the poppet element can impose constraints on the positioning of inlet and outlet ports within the valve housing, as the ports must be arranged to accommodate the external flow path around the poppet.
[0005] In many fluid system applications, there is a desire to achieve higher flow rates while maintaining compact valve dimensions. Similarly, valve designers often seek greaterflexibility in port positioning to accommodate various installation requirements and system configurations. These considerations are particularly relevant in applications such as pneumatic control systems, hydraulic systems, and other fluid handling applications where space constraints and flow performance are factors in system design.
[0006] It may thus be desirable to have a valve configuration that can provide enhanced flow characteristics while offering greater design flexi bi 1 i ty. It with respect to these and other considerations that the disclosure made herein is presented.SUMMARY
[0007] This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
[0008] In a first example implementation, the present disclosure describes a poppet for a valve. The poppet comprises a poppet body that is generally cylindrical. The poppet comprises a stem that is disposed at least partially within the poppet body, wherein the stem is connected to an interior surface of the poppet body via a plurality of webs disposed in a circular array about the stem. The poppet comprises a plurality of through-channels formed within the poppet between respective webs of the plurality of webs.
[0009] In a second example implementation, the present disclosure describes a valve. The valve comprises a valve body. The valve comprises a valve actuator. The valve comprises a plunger that is movable by the valve actuator. The valve comprises an inlet port for receiving fluid and an outlet port for discharging fluid. The valve comprises a seat member. The valve comprises a spring. The valve comprises the poppet of the first example implementation where the spring biases the poppet toward the seat member to block fluid flow from the inlet port to the outlet port when the actuator is unactuated. When the valve actuator is actuated, the plungerpushes the stem, thereby moving the poppet off the seat member and allowing fluid flow from the inlet port through the plurality of through-channels to the outlet port.
[0010] In a third example implementation, the present disclosure describes a method of operating the valve of the second example implementation.

[0019] The following description sets forth exemplary' aspects of the present disclosure. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure. Rather, the description also encompasses combinations and modifications to those exemplary7aspects described herein.
[0020] The present disclosure describes implementations that relate to a flow-through poppet for valves and regulators. Particularly, within examples, disclosed herein is a poppet and valve with a configuration that may allow for a higher fluid flow rate for a given valve size and provide flexibility in locating the inlet and outlet ports of the valve.
[0021] Traditional valves may include a poppet that is seated when a valve is unactuated to block flow between two ports. When the valve is actuated, the poppet shifts, and fluid is allowed to flow over the poppet. This configuration ty pically limits the fluid flow rate for a particular valve size. Further, this configuration may also force locating the supply and discharge ports in particular locations in a body of the valve.
[0022] The flow-through poppet technology described herein addresses these limitations by providing a poppet configuration that enables fluid to flow through the poppet rather than around the exterior of the poppet. This flow-through design may provide enhanced flow characteristics and increased design flexibility' compared to traditional poppet configurations. The flow-through poppet may allow for higher fluid flow rates within a given valve size constraint and may provide greater flexibility in positioning inlet and outlet ports within the valve body.
[0023] The flow-through poppet may be implemented in various fluid control applications, including valves and regulators used in pneumatic and hydraulic systems. The technology may be particularly beneficial in applications where space constraints limit valve size but high flow rates are desired, or where specific port positioning requirements exist due to system integration considerations.
[0024] The following description first presents a traditional poppet valve configuration for comparison purposes, illustrating the flow path limitations and design constraints associated with conventional approaches. Subsequently, the description details the improved flow-through poppet valve configuration, explaining the structural features that enable fluid flow through the poppet and the resulting performance and design advantages.
[0025] Referring to FIG. 1, a traditional valve 10 includes a valve body 12 that houses the internal components of the traditional valve 10. A plunger 14 may be positioned at an upper portion of the valve body 12 and may be configured to move linearly within the valve body 12 when actuated by an actuator. The traditional valve 10 may include a poppet 16 comprising a stem 18 and a poppet body 20. The stem 18 may extend upward and interface with the plunger 14, while the poppet body 20 may be generally cylindrical and solid in construction.
[0026] The valve body 12 may include a seat 38 against which the poppet 16 may be configured to seal when the traditional valve 10 is in a closed position. A spring 36 may be positioned below the poppet 16 and may bias the poppet 16 upward toward the seat 38, maintaining the traditional valve 10 in a normally closed configuration.
[0027] The traditional valve 10 may include multiple sealing elements to prevent fluid leakage. For example, a seal 22 may be positioned to seal between portions of the valve body 12. Another seal 24 may be positioned around the poppet 16 (particularly the poppet body 20). Another seal 26 may be located at around the stem 18 of the poppet 16 as shown. A backup seal 27 may be provided adjacent to the seal 26 to provide additional sealing capability.
[0028] The traditional valve 10 may further include a first port 28 and a second port 30. The first port 28 may be configured to receive fluid from a source of fluid (e.g., a pump or compressor), while the second port 30 may be configured to discharge fluid to a downstream component. In the closed position shown in FIG. 1, the poppet 16 may block fluid flow between the first port 28 and the second port 30.
[0029] With reference to FIG. 2, the poppet 16 may include the poppet body 20 that is generally cylindrical in shape. The stem 18 may extend axially from the poppet body 20. The poppet body 20 may feature a flanged portion 32 that extends radially outward from the cylindrical body. The flanged portion 32 may include an annular groove configured to accommodate a seal 34. Thus, the seal 34 may be disposed within the annular groove of the flanged portion 32. The poppet body 20 is solid with no fluid channels formed therein, requiring fluid to flow over the exterior of the poppet 16 rather than through the poppet 16.
[0030] Referring to FIGs. 1-2 together, during operation of the traditional valve 10, when the plunger 14 moves downward upon actuation, the poppet 16 may be displaced from the seat 38, allowing fluid to flow from the first port 28, over the exterior of the poppet body 20, and to the second port 30. This configuration where fluid flows over the poppet 16 may limit the flow area through which fluid flow s and may thus limit the fluid flow rate for a particular valve size. The solid construction of the poppet body 20 may create flow restrictions as fluid may be forced to navigate around the exterior surfaces of the poppet body 20, creating turbulence and pressure losses that reduce overall flow efficiency. With this configuration, the flow rate may be controlled and limited by the stroke of the plunger 14 and the poppet 16.
[0031] The traditional poppet configuration may also impose constraints on port positioning within the valve body 12. The requirement for fluid to flow' around the exterior of the poppet body 20 may dictate specific spatial relationships between the first port 28 and the second port 30, limiting design flexibility and potentially complicating integration into various system configurations. The flow path geometry may require the first port 28 to be positioned to allow adequate flow distribution around the poppet body 20, while the second port 30 may need to be located to effectively collect the fluid after the fluid passes over the poppet 16.
[0032] Referring to FIG. 3, a valve 100 may provide an improved configuration that addresses the limitations of traditional poppet designs. The valve 100 may include a valve body102 that houses the internal components of the valve 100. The valve 100 may be configured as a pilot-operated valve where pressurized fluid may be received at a valve actuator and when actuated, may allow pressurized fluid to pass through to cause a plunger to move.
[0033] Particularly, the valve 100 may include a valve actuator 103 positioned at an upper portion of the valve body 102. The valve actuator 103 may be a solenoid actuator that may receive pressurized fluid from a source of fluid and may allow the pressurized fluid to flow through an actuation fluid passage 105 when activated by a command signal from a controller. The actuation fluid passage 105 may extend through the valve body 102 to facilitate fluid communication for actuation purposes. The actuation fluid passage 105 may provide a pathway for pressurized fluid to reach and actuate internal components of the valve 100.
[0034] A plunger 104 may be positioned within the valve body 102 and may be movable in response to pressurized fluid delivered through the actuation fluid passage 105. The plunger 104 may be configured to move linearly within the valve body 102 when the valve actuator 103 is activated, thereby transmitting actuation force to other components within the valve 100.
[0035] The valve 100 may include a poppet 106 positioned below the plunger 104. The poppet 106 may include a stem 118 that may interface with the plunger 1 4. The stem 118 may be configured to receive actuation force from the plunger 104 and transmit such force to move the poppet 106 within the valve body 102.
[0036] The valve body 102 may include an interior configuration that accommodates the poppet 106 and associated sealing components to enable proper valve operation in both closed and open positions. For example, the valve 100 may include multiple seals to prevent fluid leakage at various locations within the valve body 102. A seal 108 may be positioned around the plunger 104. In an example, the seal 108 may be a cup-shaped seal such as a U-cup seal. A seal 110 may be positioned around a seat member 138. a seal 112 may be located around thestem 118, and a seal 114 may be positioned around the poppet 106 as shown. These seals may maintain fluid containment and prevent leakage to an external environment of the valve 100.
[0037] The seat member 138 may be formed as a disk. The seat member may accommodate a face seal 136 that engages with the seat member 138 in the closed position shown in FIG. 3, thereby blocking fluid flow through the valve 100. A spring 140 may be positioned to engage the poppet 106 and may bias the poppet 106 toward the seat member 138 to maintain the closed position when the valve actuator 103 is unactuated.
[0038] The valve 100 may include an inlet port 142 and an outlet port 144. The inlet port 142 may be configured to receive fluid from a source of fluid such as a pump or compressor. The outlet port 144 may be configured to be fluidly coupled to a fluid consuming device such as an actuator that may be controlled by the valve 100. In the closed position illustrated in FIG.3, the poppet 106 and the face seal 136 may be seated against the seat member 138, preventing fluid flow from the inlet port 142 to the outlet port 144.
[0039] Referring to FIG. 4, the poppet 106 may include a poppet body 116 that is generally cylindrical in shape. The poppet body 116 may provide a structural framework that enables fluid flow through the poppet 106 rather than around the exterior surfaces as in traditional poppet designs.
[0040] As depicted, the stem 118 may be disposed at least partially within the poppet body 116, and may particularly be positioned at a center of the poppet body 116 along a central longitudinal axis of the poppet body 116. The central positioning of the stem 118 may provide structural stability while allowing for the formation of flow passages within the poppet body 116.
[0041] The stem 118 may be connected to an interior surface of the poppet body 116 via a plurality of webs arranged in a circular array about the stem 118. The plurality of webs may provide structural support between the stem 118 and the poppet body 116 while defining flowpassages therebetween. Specifically, the plurality of webs may include a web 120, a web 122, and a web 124. The web 120, the web 122, and the web 124 may be distributed circumferentially around the stem 118 to provide structural integrity while maintaining open flow paths through the poppet 106.
[0042] A plurality7of through-channels may be formed within the poppet 106 between respective webs of the plurality' of webs. The plurality' of through-channels may enable fluid to flow longitudinally through the poppet body 116 rather than being forced to navigate around exterior surfaces. For example, a through-channel 126 may be formed between the web 120 and the web 122, providing a first flow passage through the poppet 106. A through-channel 128 may be formed between the web 122 and the web 124, providing a second flow passage through the poppet 106. A through-channel 130 may be formed between the web 124 and the web 120, providing a third flow passage through the poppet 106.
[0043] The cross-sectional area of each through-channel may be defined by the geometric boundaries formed by' adjacent webs and the interior surface of the poppet body 116. For example, the cross-sectional area of the through-channel 126 may be bounded by the web 120 on one side, the web 122 on the other side, and the interior cylindrical surface of the poppet body 116. Similarly, the through-channel 128 may have its cross-sectional area defined by the web 122, the web 124, and the interior surface of the poppet body 116, while the through-channel 130 may be bounded by the web 124, the web 120, and the interior surface of the poppet body 116. This geometric arrangement may provide well-defined flow passages with predictable flow characteristics through the poppet 106.
[0044] The through-channel 126, the through-channel 128, and the through-channel 130 may extend longitudinally through the poppet body’ 116. creating continuous flow paths that allow fluid to pass directly through the poppet 106. This configuration may eliminate the flow restrictions associated with traditional poppet designs where fluid may be forced to flow aroundthe exterior of a solid poppet body. The through-channels may provide increased flow area and reduced pressure losses compared to traditional configurations.
[0045] As further shown in FIG. 4, the poppet body 116 may include a flanged portion 132 at one end. The flanged portion 132 may feature an annular groove 134 formed therein. The face seal 136 may be disposed within the annular groove 134, providing a sealing surface when the poppet 106 is seated against the seat member 138 as shown in FIG. 3.
[0046] The poppet 106 may also include a plurality of poppet cross-holes 141 formed in the poppet body 116. The poppet cross-holes 141 may be arranged in a circular array about the poppet body 116 and may be configured to prevent flow cut-off during operation of the valve 100. The poppet cross-holes 141 may provide additional flow paths that may maintain fluid communication even when the poppet 106 is in various positions during actuation, thereby enhancing the overall flow- characteristics of the valve 100.
[0047] Referring to FIG. 5, the valve 100 may transition from the closed position to an open position through actuation of the valve actuator 103. When the valve actuator 103 is activated, pressurized fluid may be allowed to flow through the actuation fluid passage 105 into a chamber 146 positioned above the plunger 104. The chamber 146 may receive the pressurized fluid and may apply pressure to an upper surface of the plunger 104, creating a downward force that overcomes the biasing force of the spring 140.
[0048] As pressurized fluid accumulates in the chamber 146, the plunger 104 may be pushed downw ard w-ithin the valve body 102. The downward movement of the plunger 104 may cause the plunger 104 to push the stem 118 of the poppet 106. The force transmitted through the stem 118 may cause the poppet 106 to move downward against the biasing force of the spring 140, thereby compressing the spring 140.
[0049] The downward movement of the poppet 106 may unseat the face seal 136 from the seat member 138, creating a flow area 148 between the poppet 106 and the seat member 138.The flow area 148 may provide a pathway for fluid communication between the inlet port 142 and the outlet port 144. The size of the flow area 148 may be determined by the extent of downward movement of the poppet 106, which may be controlled by the pressure applied through the actuation fluid passage 105.
[0050] In the open position shown in FIG. 5, fluid may be allowed to flow' from the inlet port 142 through the poppet 106 (via the through-channels 126, 128, 130) to the outlet port 144. The fluid flow' path is indicated by a flow line 150, which demonstrates that fluid flow s through the internal structure of the poppet 106 rather than around the exterior surfaces. The flow' line 150 show's that fluid enters through the inlet port 142, passes through the through-channels formed between the w ebs within the poppet body 116, and exits through the outlet port 144.
[0051] The flow-through configuration may provide enhanced flow characteristics compared to traditional poppet designs. The through-channels w ithin the poppet 106 may allow fluid to flow directly through the poppet body 116, utilizing the internal volume of the poppet 106 as part of the flow path. This configuration may reduce flow restrictions and pressure losses that may occur when fluid is forced to navigate around the exterior of a solid poppet body as in traditional designs.
[0052] The spring 140 may remain compressed in the actuated state shown in FIG. 5, storing potential energy that may be released when the actuation pressure in the chamber 146 is reduced or removed. When the valve actuator 103 is deactivated, the pressurized fluid in the chamber 146 may be vented or redirected, reducing the downward force on the plunger 104. The spring 140 may then expand, pushing the poppet 106 upward and returning the face seal 136 to a seated position against the seat member 138, thereby closing the valve 100 and blocking fluid flow between the inlet port 142 and the outlet port 144.
[0053] The flow-through poppet configuration may provide several advantages over traditional poppet designs. The ability for fluid to flow through the poppet 106 rather than around the exterior may enable higher flow rates within a given valve size constraint. The through-channels may provide increased effective flow area compared to the annular flow area available around a traditional solid poppet body. The flow area and flow rate are no longer controlled solely based on the stroke of the poppet 106. Additionally, the flow-through design may provide greater flexibility in positioning the inlet port 142 and the outlet port 144 within the valve body 102, as the flow path may not be constrained by the need to navigate around exterior surfaces of the poppet 106.
[0054] The flow-through poppet valve technology described herein may be implemented in various applications and system configurations where enhanced flow characteristics and design flexibility' are beneficial. The technology may be particularly suitable for applications requiring high flow rates within space-constrained environments or where specific port positioning requirements exist due to system integration considerations.
[0055] For example, the valve 100 may be implemented in a central tire inflation system (CTTS) where the valve 100 may replace direct acting valves. In such applications, the flow-through poppet design may match the flow of the direct acting valve within the same space, which would not be achievable using atraditional poppet. Particularly, the flow-through poppet disclosed herein may match the flow of a direct acting valve within the same space, at a lower cost and lower energy consumption.
[0056] The valve 100 may be configured with multiple stations where each station may be controlled separately while being supplied by the same air pressure source. In such multistation configurations, a supply channel may provide pressurized fluid to multiple separate stations, with each station operating independently based on individual control signals. For example, a single supply channel may provide pressurized fluid to four separate stations, witheach station including a valve 100 having the flow-through poppet configuration. Each station may be actuated independently to control fluid flow to different downstream components or systems, while sharing a common pressurized fluid source.
[0057] The multi-station configuration may provide system-level advantages in applications where multiple fluid control points are required but space and weight constraints limit the use of separate valve assemblies. The flow-through poppet design may enable each station to achieve high flow rates despite the compact packaging required for multi-station implementations. The shared supply channel configuration may reduce system complexity and weight while maintaining independent control capability for each station.
[0058] The valve 100 may be implemented in a manifold configuration for applications such as tire inflation and venting systems. In manifold implementations, multiple valves 100 may be integrated into a single manifold body, with some valves configured for inflation operations and others configured for venting operations. The manifold configuration may provide a compact solution for systems requiring both pressurization and depressurization capabilities, such as automotive tire pressure management systems.
[0059] The flow-through poppet technology may be applied to various industrial applications beyond tire inflation systems. The valve 100 may be implemented in poppet / piston regulators where the enhanced flow characteristics may improve pressure regulation performance. In such applications, the flow-through design may enable more precise pressure control while reducing the physical size of the regulator assembly. The technology may also be applied to general poppet valves used in pneumatic and hydraulic systems where improved flow-to-size ratios are desired.
[0060] The flow-through poppet configuration may be used in any valve or regulator to improve the flow-to-size ratio compared to traditional solid poppet designs. The technology may be particularly beneficial in applications where system integration requirements imposesize constraints, but high flow performance is required. The enhanced flow characteristics may enable system designers to specify smaller valve assemblies while maintaining or improving flow performance, potentially reducing system weight, cost, and installation complexify.
[0061] The flexibility in port positioning provided by the flow-through design may enable the valve 100 to be integrated into various system configurations where traditional poppet valves may not be suitable due to port orientation constraints. The ability for fluid to flow through the poppet rather than around exterior surfaces may eliminate geometric constraints that typically dictate inlet and outlet port positioning in traditional valve designs. This design flexibility may simplify system integration and may enable more efficient packaging in space-constrained applications.
[0062] The flow-through poppet configuration disclosed herein thus provides several advantages over traditional poppet designs that may enhance valve performance and design flexibility. The flow-through design may enable higher fluid flow rates in smaller valve sizes compared to conventional poppet configurations. This enhanced performance may be achieved because fluid flows through internal channels within the poppet rather than being forced to navigate around the exterior surfaces of a solid poppet body.
[0063] Traditional poppet designs may require fluid to flow over and around the exterior of the poppet body, creating flow restrictions and requiring larger valve dimensions to achieve desired flow rates. In contrast, the flow-through poppet configuration may utilize the internal volume of the poppet as part of the flow path, effectively increasing the available flow area without increasing the overall valve size. This internal flow path may reduce pressure losses and turbulence that may occur when fluid is forced to change direction around exterior surfaces.
[0064] The flow-through design may enable high flow capability with a short stroke of the poppet. Traditional poppet valves may require longer strokes to create adequate flow area around the exterior of the poppet body, particularly for high flow applications. The flow-through configuration may achieve high flow rates with minimal poppet displacement because the internal channels provide direct flow paths that are not dependent on the clearance area around the poppet exterior. This short stroke capability7may enable more compact actuator designs and faster valve response times.
[0065] The flow-through poppet configuration may provide increased flexibility7in positioning inlet and outlet ports within the valve housing. Traditional poppet designs may impose constraints on port positioning because fluid may be required to flow from one side of the poppet to the other, typically requiring the inlet to be positioned beside the poppet and the outlet above the poppet. The flow-through design may eliminate these geometric constraints because fluid may flow directly through the poppet regardless of the relative positions of the inlet and outlet ports.
[0066] The area under the poppet may become useful flow area in the flow-through configuration, whereas this area may be underutilized in traditional designs. In conventional poppet valves, the space beneath the poppet may serve primarily as a pressure chamber and may not contribute significantly to the flow path. The flow-through design may enable this space to be incorporated into the flow path, effectively increasing the total flow area available within the valve housing.
[0067] The improved flow-to-size ratio provided by the flow-through poppet technology may enable system designers to specify smaller valve assemblies while maintaining or improving flow performance compared to traditional designs. This enhanced ratio may be particularly beneficial in applications where space and weight constraints are considerations, such as mobile equipment, aerospace applications, or compact industrial systems. The ability to achieve higher flow rates in smaller packages may reduce system complexity and installation requirements.
[0068] The flow-through poppet configuration may thus enable a broader range of design configurations compared to traditional poppet valves. The flexibility in port positioning may allow valve designers to optimize valve orientation for specific installation requirements or system integration needs. The reduced dependence on stroke length for flow performance may¬ enable more compact valve designs or may allow for the integration of additional features within the same envelope as traditional valves.
[0069] The flow-through design may provide more consistent flow characteristics across different operating conditions compared to traditional poppet configurations. The internal flow channels may maintain their flow area regardless of minor variations in poppet position, whereas traditional designs may be more sensitive to poppet positioning due to the dependence on clearance areas around the poppet exterior. This consistency may contribute to more predictable valve performance and may simplify system design and calibration processes.
[0070] Referring to FIG. 6, a method 300 of operating the valve 100 may include several operational steps that enable controlled fluid flow through the flow-through poppet configuration. The method 300 may begin at step 302 with the valve 100 positioned in a closed state where the spring 140 biases the poppet 106 toward the seat member 138, causing the face seal 136 to engage with the seat member 138 and block fluid flow from the inlet port 142 to the outlet port 144.
[0071] The method 300 may proceed to step 304, which includes receiving a control signal at the valve actuator 103 to transition the valve 100 from the closed position to an open position. The method 300 may then advance to step 306, where the valve actuator 103 may be activated to allow pressurized fluid to flow through the actuation fluid passage 105.
[0072] At step 308, the method 300 may include directing the pressurized fluid into the chamber 146 positioned above the plunger 104. The method 300 may then proceed to step 310, which includes applying pressure to the plunger 104. creating a force that overcomes thebiasing force of the spring 140. The plunger 104 may be pushed within the valve body 102 in response to the applied pressure.
[0073] The method 300 may continue to step 312. where the movement of the plunger 104 may cause the plunger 104 to push the stem 118 of the poppet 106. At step 314, the method 300 may include transmitting force through the stem 118 to move the poppet 106 against the biasing force of the spring 140, thereby compressing the spring 140.
[0074] At step 316, the method 300 may include unseating the face seal 136 from the seat member 138 due to the movement of the poppet 106, creating the flow area 148 between the poppet 106 and the seat member 138. The method 300 may then proceed to step 318, which includes allowing fluid to flow from the inlet port 142 through the plurality of through-channels formed within the poppet 106 to the outlet port 144. The fluid may flow through the through-channel 126, the through-channel 128, and the through-channel 130, which are formed between the web 120, the web 122, and the web 124.
[0075] The method 300 may include maintaining the valve 100 in the open position for a desired duration by continuing to supply pressurized fluid to the chamber 146 through the actuation fluid passage 105. During this open state, fluid may continue to flow from the inlet port 142 through the through-channels within the poppet 106 to the outlet port 144, providing fluid to downstream components or systems.
[0076] To close the valve 100, the method 300 may proceed to step 320, which includes deactivating the valve actuator 103 in response to a control signal. Upon deactivation, the pressurized fluid in the chamber 146 may be vented or redirected, reducing the force applied to the plunger 104. The spring 140 may then expand, pushing the poppet 106 and returning the face seal 136 to a seated position against the seat member 138.
[0077] At step 322, the method 300 may include returning the poppet 106 to the seated position, thereby blocking fluid flow between the inlet port 142 and the outlet port 144 whenthe face seal 136 engages with the seat member 138 and returning the valve 100 to the closed position. The valve 100 may remain in the closed position until the valve actuator 103 is activated again in response to a subsequent control signal.
[0078] In some implementations, the method 300 may include modulating the flow rate through the valve 100 by controlling the extent of poppet displacement. The valve actuator 103 may be configured to provide variable actuation pressure to the chamber 146, allowing for partial displacement of the poppet 106 from the seat member 138. By varying the size of the flow area 148 between the poppet 106 and the seat member 138, the method 300 may enable proportional flow control through the valve 100.
[0079] The method 300 may include monitoring operating parameters such as fluid pressure at the inlet port 142 and the outlet port 144, actuation pressure in the chamber 146, or poppet position to provide feedback for control purposes. Such monitoring may enable closed-loop control of the valve 100 to achieve desired flow rates or pressure regulation characteristics.
[0080] In multi-station configurations, the method 300 may include independently operating multiple valves 100 that share a common pressurized fluid source. Each valve 100 may be actuated separately based on individual control signals while receiving pressurized fluid from the same supply channel. This independent operation may enable selective control of fluid flow to different downstream components or systems while maintaining a simplified fluid supply architecture.
