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. Therefore, when a process controller sends a ...
