Fisher 1052 Rotary Actuators
Fisher 1052 spring-return diaphragm rotary actuators operate splined shaft rotary valves and are suitable for on/off or throttling service. Designed for easy installation of a broad range of options: limit switches, position indicating switches, positioners, and manual over-rides.
- Single joint linkage with splined and clamped lever minimizes lost motion and improves control accuracy.
- Includes an externally accessible spring adjuster to relieve spring compression. Actuator/valve linkage is completely enclosed, yet the valve packing adjustment remains accessible.
