Quarter Turn Electric Actuator/Rotary Electric Actuator
Summary
EQS valve actuators are the new generation product of our company and can be used for driving and controlling the butterfly valves, ball valves, plug valves (part-turn with 90° movement). The actuators can be either remotely controlled, or locally controlle.
They are widely used in the fields such as oil, chemistry, power generation, water treatment, paper making.
The protection class is IP67, and the explosion proof class is d II BT4 (with lessters of EX).
This operation manual is applied for general type. For special type actuators, the additional manual will be provide.
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
