Composition of electric control valve:

Composed of a regulating valve and an electric actuator, it is a commonly used regulating instrument in automatic control systems;

The actuator is the driving device of the regulating valve, which acts according to the received signal. The force of the action is determined by the mechanical thrust/tension or torque of the actuator itself. The speed of the action is determined by the PID tuning circuit calculation of the control system, and commands are issued. The control of the controlled target is achieved through the matching of the valve core, valve port and medium, and the control of the controlled target is achieved through flow rate changes. Quality control is achieved through quantity adjustment.

The valve body component is the regulating part of the regulating valve, which directly contacts the medium and changes the throttling area of the regulating valve through the action of the valve core, achieving the purpose of regulation.
