Classification Of Valve Electric Actuators
Jan 07, 2020

The valve electric actuator can be divided into three types according to the movement mode of the output shaft.

1. Partial rotary electric actuator

The opening and closing process of the valve can be realized when the output shaft of the partial rotary electric actuator rotates less than one circle, the rotation angle is less than 360 degrees, and the output shaft rotates 90 degrees. Some rotary electric actuators are used together with butterfly valves, ball valves and plug valves.

2. Multi turn electric actuator

The output shaft of the multi rotation electric actuator rotates more than 360 degrees, and it generally needs to rotate several turns to realize the opening and closing action of the valve. The multi rotation electric actuator is mainly used with gate valve and stop valve.

3. Direct stroke electric actuator

The motion track of the output shaft of the direct stroke electric actuator is linear motion, not rotary motion.
