1 2052 Diaphragm Rotary ActuatorFisher 2052 spring-and- Diaphragm Rotary actuators areused on Rotary -shaft valve bodies for throttling oron-off applications. The 2052 may be used forthrottling service with a positioner, or it may be usedfor on-off service without a positioner. The 2052 has anISO 5211 mating interface that allows installation tonon- Fisher valves. Refer to separate bulletins for valveand positioner Compact design, smaller actuators-- Ensuresreduced valve/ Actuator envelope dimensionsleading to greater mounting versatility for bothskids and process plants, where space is at Compatible with DVC2000, DVC6200, andDVC6000 digital valve controllers; and 3610J and3620J positioners-- The new Actuator allowslinkage-less feedback, via a contact-less magneticarray, from the lever to the end-mounted window mounting of the DVC6200,DVC6000, 3610J, and 3620J is also Clamped lever to reduce lost motion-- The clampingof the lever onto a splined valve shaft, coupled withthe single pivot linkage, reduces lost motionbetween the Actuator and the valve.
2 The typicalcumulative deadband for a Fisher Rotary controlvalve assembly results in or less No bench set required-- The new nested springdesign requires no bench set. This also simplifies theactuator selection process, see table ISO 5211 mounting with optional insert-- Theactuator can now be mounted directly ontonon-spline shafts, such as Square and Double D. Thisallows the Actuator , with its enhanced control, tomount on a wider range of valves conforming to Control-Diskt Valve with 2052 Actuator andFIELDVUE DVC6200 Digital Valve Controllern Adjustable travel stops standard-- Provides theability to adjust or change the travel range by 30degrees in either direction without removing theactuator or the addition of extra Fail-safe mechanism contains no aluminum-- Allparts in the fail-safe mechanism (made of steel, castiron, and ductile iron)
