First, the definition of electric valve actuator:


The electric valve actuator is an electric actuator that controls the valve to open and close the valve. It can be divided into upper and lower parts, the upper part is the electric actuator and the lower part is the industrial valve.


Second, electric valve actuator classification:


One is a quarter-turn electric valve: it is used by a quarter-turn electric actuator with a quarter-turn valve to realize 90 degree internal rotation control of pipe fluid continuity; the other is a linear stroke electric valve: electric actuator by straight stroke It is used with the valve of the straight stroke to realize the fluid on and off of the valve on the upper and lower sides of the valve. It is usually used on a highly automated device.


Third, the principle of electric valve


Electric valve actuator operating principle: The electric valve is usually connected by an electric actuator and a valve, and becomes an electric valve after installation and debugging. The electric valve uses electric energy as power to turn on the electric actuator to drive the valve to realize the switching and regulating action of the valve. Thereby achieving the switching or regulating purpose of the pipeline medium.


Fourth, the use of electric valve actuator:


Analog adjustment for pipe media flow in liquid, gas and wind systems is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control. There can be AI feedback signals, which can be controlled by DO or AO, and are found in large pipes and dampers.
