WebFisher 3582 pneumatic valve positioners are used with diaphragm-actuated, sliding-stem control valve assemblies. This pneumatic valve positioner receives a pneumatic input signal from a control device and modulates the supply pressure to the control valve actuator, providing an accurate valve stem position that is proportional to the pneumatic input signal. WebJul 5, 2016 · A valve positioner is a device mounted on the actuator that exerts or reduces air pressure as necessary to make sure the valve achieves the correct position. When there is no positioner, the control signal goes directly to the actuator. When a positioner is installed, it intercepts this signal and then outputs a different signal to the actuator.
