Electric ball valve is a modern control equipment, usually used for pipeline media remote opening and closing (connecting, cutting off the medium) control, but also industrial automation process control in an important pipeline pressure components, widely used in industrial automation control field. It can accurately control the opening and closing of the ball valve through the electric actuator to realize the precise adjustment of the flow and pressure of liquid, gas and corrosive media. In an electric ball valve, the ball can be rotated within the seat to control the on-off and flow of fluid. The electric actuator is connected to the ball to realize the on/off operation through the electric signal. The control system is responsible for receiving the signal and controlling the movement of the actuator to adjust the status of the valve.
