3610J and 3620J Series Positioners
 |
The Type 3610J or 3610JP pneumatic positioner in combination with the Type 3622 electro-pneumatic converter becomes the Type 3620J or 3620JP positioner, respectively. This integral electro-pneumatic converter, can be factory installed or installed in the field on existing positioners.
Type 3620JP Electro-Pneumatic Positioner with Type 1061 Actuator and Design V500 Valve 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.
The positioner mounts on the actuator shows the cam feedback mechanism for a positioner mounted on the actuator. Positioner bleed air continually purges the enclosure containing the feedback lever and the feedback linkages.
To support diagnostic testing of valve/actuator/positioner packages, connectors, piping, and other hardware can be installed between the Type 3610J or 3620J series positioner and the actuator.
