DN25 Cast Iron wafer Type Lug Manual anti-corrosive Seal Butterfly Valves
The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. 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°, which can play a role in flow adjustment. When the butterfly plate rotates to 90°, the valve reaches the maximum Opening.
The wafer butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover,
it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid
