Fisher 3620JP electro-pneumatic, double-acting positioners are used with rotary actuators to accurately position control valves used in throttling applications. These rugged positioners provide a valve position proportional to a DC current input signal and mounts integrally to the actuator housing.

Features:

The positioner provides accurate, fast response and can withstand the vibrations of most plant environments. Low steady-state air consumption contributes to efficient operation.
Most of the parts for 3620JP positioners are interchangeable, requiring fewer spare parts to support these positioners.
With the cover removed, zero span and cross-over adjustments are easily accessible and can be made with a screw driver.
Easily adjustable minor loop gain fine tunes the positioner to optimize dynamic response for each specific actuator size and application.
Changes in supply pressure have minimal effect on positioner operation.
Case, components, and gasket materials withstand harsh environments. Positioner bleed air purges internal parts and actuator housing for additional protection.
Simple adjustments permit switching between direct and reverse action; no additional parts are required.
