The type RPC positioner is an electropneumatic positioner for pneumatically operated control valves with single-acting and double-
acting actuators. The type RPC positioner is assembled on the pneumatic actuator and regulates the position of the valve. The type
RPC positioner therefore continuously compares the current position (actual position value) with the specification of the external
standard signal (position setpoint value). If there is a control difference, the electropneumatic control system causes the actuator to
correct the actual position value accordingly.
