Overview

The electric single seat 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.

1control valveProduct Introduction：

ZAZP, ZAZN, and ZAZM electric control valves are composed of electric actuators and various valve bodies (single seat, double seat, sleeve), and have the characteristics of various valves. The electric control 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 adjustment in the production process. Widely used in automatic control of industries such as power, metallurgy, light industry, food, petroleum, and chemical.
