Fisherr 3610J and 3620J Positioners and 3622
Electro-Pneumatic 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.

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

ELECTRO­PNEUMATIC
CONVERTER

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.
