FISHER 3610J/3620J Positioners - 3622 Converter

Fisher 3610J or 3610JP pneumatic and 3620J or 3620JP electro-pneumatic positioners are used in combination with either single or double-acting rotary actuators to accurately position control valves used in throttling applications. The positioner mounts integrally to the actuator housing. These rugged positioners provide a valve position proportional to a pneumatic or a DC current input signal.

Features include

• The 3610J or 3610JP pneumatic positioner in combination with the Fisher 3622 electro-pneumatic converter becomes the 3620J or 3620JP positioner, respectively. This integral electro-pneumatic converter, can be factory installed or installed in the field on existing positioners.
• The electro-pneumatic converter receives the DC current input signal and provides a proportional pneumatic output signal through a nozzle/flapper arrangement.
• The output signal from the converter becomes the input signal pressure to the pneumatic positioner, eliminating the need for a remote mounted transducer.
• To support diagnostic testing of valve/actuator/positioner packages, connectors, piping, and other hardware can be installed between the 3610J or 3620J positioner and the actuator.
