Product Description

Product Description

The disc of the Wafer Butterfly Valve is installed in the diameter direction of the pipe. In the butterfly valve body cylindrical channel, disc shaped butterfly plate around the axis of rotation, rotation Angle between 0°-90°,can play the role of flow regulation, when the butterfly plate rotation to 90°, the valve to reach the maximum opening.Wafer butterfly valve is with simple structure, small size, light weight, only by a few parts. And only need to rotate 90° canquickly open and close, simple operation, and the valve has good fluid control characteristics.
