Abstract
Embodiments of the present disclosure include a system for determining a valve member position. The system includes a valve having a flow passage extending therethrough. The system also includes a valve member positioned in a cavity that intersects the flow passage, the valve member coupled to a valve stem that axially translates the valve member between an open position and a closed position. The system includes an actuator coupled to the valve stem, the actuator providing a motive force to drive the axial movement of the valve member via the valve stem. The system includes a closure cap coupled to the actuator, the closure cap comprising a sensor feature arranged within an interior portion of the closure cap, the sensor feature arranged to react to an input from an actuator piston indicative of an actuator piston position within the interior portion of the closure cap.
