The electric butterfly valve is composed of an electric actuator and a valve. The electric actuator rotates at 90 degrees, and there are two control methods: power switch and control type. According to the rotation of the electric actuator, the butterfly valve is activated and closed. It has a manual control function, which switches the butterfly valve on and off according to manual control when turning off the power.

Electric butterfly valves are available in standard and fully intelligent versions.

(1) Universal motorized butterfly valve - When connected to its motor, the gate valve opens or closes, depending on the forward and reverse motor;

(2) Intelligent type - such as AC380V, when supplied with AC380V, the motor does not move and the internal structure control circuit board can work. When inputting 4-20mA current for it, make the corresponding posture. Turn off at 4mA and turn on at 20mA. And there is a 4-20mA analog input control signal to reflect the opening size of its gate valve.
