Electric Control Valve is an important actuator instrument in industrial automation process control. It employs advanced electric drive technology and receives signals from industrial automation control systems to drive the valve, changing the cross-sectional area between the valve core and valve seat to control the flow, temperature, pressure and other process parameters of the medium in the pipeline, achieving automatic regulation. Electric control valves feature compact structure, high precision, and fast response speed, and are widely used in automatic control systems in industries such as power, chemical, metallurgy, and environmental protection.
