Brief introduction
The ZAZM electric sleeve regulating valve is powered by a single-phase AC 220V 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 regulation in the production process. ZAZM sleeve valves are widely used in automatic control of industries such as power, metallurgy, light industry, food, petroleum, and chemical. The ZAZ (P, N, M) electric control valve is composed of an electric actuator and various valve bodies (single seat, double seat, sleeve), and has the characteristics of various valves.
