Fisher 1051 and 1052 Diaphragm Rotary Actuators

Both designed for on-off service or for throttling service, Fisher® 1051 and 1052 actuators control splined shaft rotary valves, like eccentric disc, for example, (Fisher® 8510B and 8560), 8532 and 9500, CV500 and V500 and Vee-Ball™ (V150, V200 and V300) valves.

These spring-return diaphragm rotary actuators exhibit a single major difference between them. While the 1051 generally includes a valve positioner in throttling service, the 1052 can perform with or without a positioner – contingent upon servicing needs. The 1052’s included spring adjuster makes this possible.
