Electric Control Valve Consisting of valve and actuator and connecting with pipeline, the electric control valve is the final control unit of pipeline through changing the technological parameters, such as media flow, pressure, temperature and liquid level, after receiving the DC4～20mA (DC1～5V) analog quantity signal and intermittent contact control signal transmitted by DCS control system, controller and computer. With the features of simple structure, high control accuracy, small pressure drop, long service life and easy maintenance, it is widely used in many industries, such as, electricity, metallurgy, cement, chemical industry, urban heating system, waste heat generating, water treatment, biomass power generation, desulfurization and others.
