First of all, what is an electric actuator valve?

An electric valve actuator consists of an electric device and a valve, serving as the mechanism for opening and closing the valve.

These electric actuators are connected to valves, forming electric actuator valves post-installation. Electric valves utilize electrical energy to power the actuator, aiding in the valve's on-off and regulatory functions, thus controlling the flow within pipelines.

Important considerations when choosing electric actuator valves:

1. Output speed: The opening and closing speed must be moderate to avoid water hammering, thus the speed must be selected according to the usage conditions.

2. Control torque: After defining specifications, ascertain the control torque to avoid motor overload.

3. Control form: Electric actuators can be divided into on-off and regulating types, with the latter further divided into current signals and voltage signals.

4. Control voltage: Standard voltages for electric actuators include AC220V, AC380V, and DC24V.

5. Operating torque: This is a key parameter, where the output torque should ideally be 1.2 to 1.5 times the maximum operating torque of the valve.

6. Electric device: Options vary between those without thrust plates and others that convert torque into thrust via a stem nut.

7. Output shaft turns number: This relates to the nominal diameter of the valve and valve stem pitch, calculated using M=H/ZS.

8. Valve stem diameter: For multi-turn valves, ensure that the diameter of the electric actuator's hollow output shaft exceeds that of the valve's stem for proper assembly.
