  1. Overview:

Part of the rotary valve electric actuator mechanism is suitable for butterfly valves, ball valves, plug valves and other 90-degree angular stroke valves. It is used to control the opening and closing adjustment of the valve. With accessories, it can be controlled remotely or on-site. Electric valve products are widely used in the power industry, petrochemical industry, food industry, textile industry, paper industry, pharmaceutical industry, water plant and sewage treatment industries, with a wide range of applications.

  1. Type classification of actuator:

Part-turn electric actuators can be divided into: outdoor type, explosion-proof type (B), integral switch type (Z), integral adjustment type (T), explosion-proof integral type, explosion-proof integral adjustment type, etc.

  1. Production standard specifications:

The performance of the part-turn electric actuator meets the requirements of JB/T8528-1997 (technical conditions for ordinary valve electric devices) and has been verified by the National Electrical Product Quality Supervision and Testing Center.

  1. Introduction of model examples:

Q10-1B means that the electric actuator is part-turn, the output torque is 100N.m, the output speed is 1r/min, and the explosion-proof type.

Q120-0.5T means that the electric actuator is part-turn, the output torque is 1200N.m, the output speed is 0.5r/min, and the overall adjustment type

  1. Working environment and main technical parameters:

(1) Power supply:

Conventional: single-phase 220V, three-phase 380V

Special: single-phase 110V, three-phase 415V

(2) Working temperature:


  1. Working medium:

Outdoor type is used in places where there is no flammable, explosive and non-corrosive medium. Explosion-proof electric actuator products are dI and dIIBT4. dI is suitable for non-excavation working faces of coal mines. dIIBT4 is used in factories. The use environment is explosive gas.

  1. Anti-riot level:

IP55, IP65, IP67

  1. Structure:

The Q-type part-turn electric actuator mechanism is composed of a valve dedicated motor, reducer, stroke controller, torque controller, opening indicator, handwheel, mechanical limit mechanism, etc. The explosion-proof type is based on the outdoor type. The explosion-proof surface is increased, and an explosion-proof junction box and an explosion-proof motor are used.
