Fisher 3582 Positioner

The Fisher 3582 pneumatic valve positioners are used with diaphragm-actuated, sliding-stem control valve assemblies. 

The pneumatic valve positioners receive a pneumatic input signal from a control device and modulate the supply pressure to the control valve actuator, providing an accurate valve stem position that is proportional to the pneumatic input signal.
