How to Install the Wafer Type Manual Butterfly Valve

The butterfly plate of the wafer type manual butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 ° - 90 °. When it rotates to 90 °, the valve plate is fully open. The butterfly valve is simple in structure, small in size, light in weight and only composed of a few parts. It can be opened and closed quickly by rotating 90 °, and the operation is simple. At the same time, the valve has good fluid control characteristics.
