Wafer butterfly butterfly plate installed on the diameter of the pipe direction. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation Angle for 0 ° and 90 °, can have the effect of flow control, when the butterfly plate rotation to 90 °, the maximum opening of the valve. The wafer butterfly valve has simple structure, small volume, light weight, only by a few parts. And only need to rotate 90 ° can rapid opening and closing, simple operation, at the same time, the valve has good flow control characteristics.
