The typical shape of electric control valve, which consists of two separable actuators and control valve (regulating mechanism) parts. The upper part is the actuator, which receives the 0-10madc or 4-20madc signal from the regulator and converts it into the corresponding linear displacement to push the lower regulating valve to act and directly regulate the flow of fluid. The actuators of all kinds of electric regulating valves are basically the same, but there are many types of regulating valve (regulating mechanism) structures due to different use conditions, the most commonly used are straight single seat and straight double seat.

Electric control valve is an industrial field executive instrument composed of regulating valve body and different electric actuators. It receives 4-20mA or pulse signal from the regulator to carry out closed-loop control and realize automatic control of flow, pressure, temperature, liquid level and other parameters. It can also select intelligent electric actuator to realize digital transmission with DCS, PLC and other devices to form a more intelligent control Manufacturing system. The power supply voltage of electric control valve is 220V and 380V. The flow characteristics of electric control valve, electric single seat control valve and electric small flow control valve are equal percentage, linear and fast.
