Butterfly valve simple structure, small size, light weight, only by a few parts. And only need to rotate 90° Can quickly open and close, simple operation, while the valve has good fluid control characteristics. Butterfly valve disc is installed in the pipe diameter direction. In the butterfly valve body cylindrical channel, disc disc around the axis of rotation, rotation Angle between 0° ~90° , rotation to 90° , the valve is fully open state. When the flanged butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop produced by the valve is very small, so it has good flow control characteristics.
