FISHER CONTROLS-3622-VALVE PNEUMATIC POSITIONER SERIES 3600 Simple Type: pneumatics
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. The positioner mounts on the actuator as shown below. Figure 1 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 3610J or 3620J positioner and the actuator.
