Product details

The ZAZP electric control valve is composed of an electric actuator and a single seat valve body, and has the characteristics of various valves. The electric control valve is powered by a single-phase AC 220V or 380V power supply and receives a unified standard electrical signal of 0-10mADC or 4-20mADC. It automatically controls the valve opening to achieve automatic control of parameters such as working flow rate, pressure, temperature, and liquid level. It is one of the components of automatic adjustment in the production process. Widely used in automatic control of industries such as power, metallurgy, light industry, food, petroleum, and chemical.
