What is Electric Butterfly Valve ?

Electric Butterfly Valve is a quarter-turn valve that rotates 90 degrees to open or close the media flow. It has a circular disc, also known as the butterfly, found at the center of the body that functions as the closing mechanism of the valve. The disc is connected to an actuator or handle through the shaft, which goes through from the disc to the top of the valve body.

The movement of the disc will determine the position of the butterfly valve.The resilient seated butterfly valve lug type can work as isolating valve if the disc rotates a full 90-degree turn, the valve is completely opened or closed.

Electric Butterfly Valve is also used as flow regulalting valve,if the disc does not rotate to a full quarter-turn, it means the valve is partially open,we can regulate the flow of fluids by various openning angle.
