FISHER™ 3610J & 3620J Positioners

The FISHER 3610J /3620J Pneumatic Positioners can be used with single acting rotary actuators to precisely position control valves used in throttling applications. These positioners are rugged, provide valve positioning proportional to the pneumatic input signal or DC current input signal, and are mounted as a single unit to the actuator housing.

Main Features

The positioner provides accurate, fast response and withstands vibration in most factory environments.
Adjustments can be easily made with a screwdriver by removing the cover.
The small loop gain is easily adjustable, allowing the positioner to be fine-tuned for each specific actuator size and application to optimize dynamic response.
The effect of supply pressure variations on positioner operation is minimized.
The housing, components and gaskets are made of materials that can withstand harsh operating environments. Positioner venting cleans internal components and actuator housings for additional protection.
Simple adjustment, switchable between positive and negative action; no additional parts required.
