There are several types of electric actuators: angular-stroke electric actuators, straight-stroke electric actuators, fine-sized electric actuators, electric regulating valves, PID electric regulating actuators and solenoid valves.
Angle travel electric actuator: This type of electric actuator is suitable for butterfly valves, ball valves, plug valves, etc., which use 90-degree switches.
Straight-stroke electric actuator: The movement of the output shaft is linear, not a rotation. This type of electric actuator is suitable for single-seat control valves, double-seat control valves, etc. for linear motion.
Fine and small electric actuators: The rotation of the output shaft of the fine and small electric actuators is more than one turn, that is, more than 360 degrees. The multi-turn capability successfully achieves the valve's opening and closing process control capabilities. Such electric actuators are suitable for use with gate valves, shut-off valves, etc.
So what is the relationship between the actuator and the valve?
The small and precise electric actuator is installed on the valve pipeline, and the pipeline medium is controlled and adjusted mainly through some opening and closing functions. In addition, the actuator is installed on the valve, which is used to control or adjust the valve switch.
Should every valve be equipped with an actuator?
Generally, the ordinary manual explosion-proof electric does not have an actuator, such as an electric valve, it must be combined with the electric actuator to use. This demand is subdivided according to the valve model, caliber, torque, pressure, medium, etc. In theory, each valve can be worn with an actuator. The specific application of the explosion-proof electric valve depends on the needs of the user.
