The working principle of electric actuator:

The basic operation of the electric actuator is as follows: When the rotor rotates, the motor also rotates. This causes the spindle ball screw to move back and forth. The piston rod connected to the ball nut screw uses this action to produce a linear motion.

Types of electric actuators:

By rotation angle option:
Right angle rotary (90 degrees) electric actuator for ball/butterfly valves,
Multi-turn type (360 degrees) for gate/globe valves.
By characteristics:
Open/close type electric actuators,
Modulating electric actuators,
Intelligent electric actuators,
Multi-turn electric actuator,
Explosion-proof electric actuator,
Underwater type electric actuators,
Fail-safe/fail-open type.
