Overview

The electric control valve is composed of a 3810L series electronic electric actuator and a straight through double seat valve. The electric actuator has a servo system inside, which does not require a separate servo amplifier. By inputting a 220V (AC) power supply and a 4-20mA (DC) signal, the valve opening can be controlled, thereby achieving continuous adjustment of process parameters such as pressure, temperature, flow rate, and liquid level of the medium. This product has the characteristics of sensitive action, convenient energy access, rapid signal transmission, as well as small unbalanced force, large allowable pressure difference, and large flow coefficient. It is widely used in industries such as power, metallurgy, chemical, and textile
