Valve Stem Position. The curves shown are typical of those available from valve manufacturers. control valve positioner is a device designed to actively compare valve stem position against the control signal, adjusting pressure to the actuator. the percent of flow through the valve is plotted against valve stem position. with constant pressure drop, the flow rate through any valve is directly proportional to that valve’s \(c_v\), and with a “linear” valve design the \(c_v\) (and therefore the. a positioner can be considered as a simple closed loop/feedback control system where the valve’s stem position is the process variable (pv), the command signal to the positioner is the setpoint (sp), and the positioner’s signal to the valve actuator is the manipulated variable (mv) or output. a valve positioner is a device used to increase or decrease the air load pressure driving the actuator of a control valve until the valve’s stem reaches a position balanced to the.
