Metal Seated Seal Butterfly Valves

     Metal Seated Seal Butterfly Valves 

The butterfly plate of the metal hard seal butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is in a fully open state.
