Fisher 3620J
The Fisher 3620J electro-pneumatic single-acting positioners can be used with rotary actuators and precisely position control valves used in throttling applications. These positioners are rugged and provide valve positioning proportional to the pneumatic input signal and are mounted as a unit to the actuator housing.
FEATURES
The positioner provides accurate, fast response and can withstand the vibrations of most plant environments.
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.
