Quarter-turn/ Multi-turn Electric Valve Rotary Actuator Structure
The actuator is made of the folling parts:
1. Enclosure: top cover and mounting base
2. Driving part: driven by highly efficient, hermetic, squirrel caged type motor
3. Rotating part: double worm gearing
4. Manual override: handwheel and clutch
5. Modulating part: separated with the actuator body, for modulating easily
6. Torque switch and limit switch
7. Travel testing and feedback
