Fisher 3582I Positioner
|
Summary
| The 3582 Series pneumatic valve positioners and the Type 3582i electro-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.
