Valve Position. The valve’s stem position is the process variable (pv), the command signal to the. The curves shown are typical of those available from valve manufacturers. Web 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. Web positioners essentially act as control systems within themselves (note 2 ): Web the percent of flow through the valve is plotted against valve stem position. Web analog position sensors, such as potentiometers and hall effect sensors, measure valve position continuously to allow precise position control of the valve. Web a valve positioner acts as an intermediary between the control system, actuator, and the control valve itself. Web 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.
