Embodiment Construction

[0017] The description that follows includes exemplary devices, methods, techniques and instruction sequences that implement the techniques of the inventive subject matter. It is understood, however, that the various embodiments described may be practiced without these specific details.

[0018] figure 1 A schematic diagram of a piping system 100 having a valve 102 with a valve position indicator 104 is depicted in accordance with one embodiment. The tubing system 100 may be any suitable tubing system requiring flow control within the tubing system 100 . Valve 102 may have an actuator 106 configured to move valve 102 between an open position and a closed position. Actuator 106 may be any suitable actuator including, but not limited to, pneumatic actuators, hydraulic actuators, electric actuators, handwheels, levers, and the like. The actuator 106 may have an actuator shaft 108 configured to actuate the valve position indicator 104 when the valve 102 is moved between the ope...

Abstract

The disclosure relates to an embodiment of a valve position indicator having an indicator cover having at least one window and a rotor configured to be at least partially within the indicator cover. The rotor has an indicator surface with one or more position indicators wherein at least one of the position indicators is configured to align with the window on the indicator cover, thus indicating the position of a valve. A light may be positioned proximate the rotor and configured to illuminate the position indicator. The valve position indicator may also include an array of LED lights bordering the rim of the indicator cover. The valve position indicator may alternatively include the array of LED lights without the indicator cover.

Description

technical field [0001] The technical field relates to valve position indicators. Background technique [0002] Valves are used in numerous applications to control the flow of fluid through piping systems. There are many different types of valves used to control flow, such as ball valves, gate valves, butterfly valves, needle valves, check valves, and the like. Ball valves, butterfly valves, needle valves and gate valves can be actuated between open and closed positions using actuators, handwheels or manual levers. It can be difficult to know the position of the valve from the position of an actuator such as a handwheel or electric actuator. Accordingly, there is a need for an improved valve position indicator for a valve. Another need for valve indicators is better communication of valve position through the display. Contents of the invention [0003] A valve position indicator has an indicator cover with at least one window and a rotor configured to reside at least pa...
