Fisher 2052 spring-and-diaphragm rotary actuators are used on rotary-shaft valve bodies for throttling or on-off applications. The 2052 may be used for throttling service with a positioner, or it may be used
for on-off service without a positioner. The 2052 has an ISO 5211 mating interface that allows installation to non-Fisher valves. Refer to separate bulletins for valve and positioner information.
Compatible with DVC2000, DVC6200, and DVC6000 digital valve controllers; and 3610J and
3620J positioners-- The new actuator allows linkage-less feedback, via a contact-less magnetic
array, from the lever to the end-mounted DVC2000. Integral window mounting of the DVC6200,
DVC6000, 3610J, and 3620J is also available.
