The most common definition of an actuator is: a drive device that can provide linear or rotary motion, which uses a certain driving energy source and works under a certain control signal. The actuator uses liquid, gas, electricity or other energy and converts it into a driving action through a motor, cylinder or other device. Its basic types are part-turn, multi-turn and linear-turn.
Part-turn electric actuator is suitable for butterfly valve, ball valve, plug valve, damper valve etc.
Multi-turn electric actuator is suitable for gate valve, globe valve, throttle valve etc.
Linear-turn electric actuator is suitable for control valve etc.
