Summary
Â
EQS valve actuators are a new generation of products from our company, designed for driving and controlling butterfly valves, ball valves, and plug valves (with 90° part-turn movement). These actuators can be operated remotely or locally.
Â
They are widely used in industries such as oil, chemical, power generation, water treatment, and paper manufacturing.
Â
The protection class is IP67, and the explosion-proof class is d II BT4 (with EX certificates).
Â
This operation manual applies to general types. For special types, an additional manual will be provided.
Â
Structure
Â
The actuator consists of the following parts:
Â
1. Enclosure: top cover and mounting base
2. Driving part: highly efficient, hermetic, squirrel-cage motor
3. Rotating part: double worm gearing
4. Manual override: handwheel and clutch
5. Modulating part: separated from the actuator body for easy adjustment
6. Torque switch and limit switch
7. Travel testing and feedback system
