Electronic electric control valve, consisting of an electric actuator and a control mechanism. Built-in servo amplifier allows valve opening to be controlled by inputting a 4-20mA control signal, enabling precise regulation of pressure, flow rate, liquid level, temperature and other parameters. Widely used in industries such as petroleum, chemical, power generation, and water treatment.
