API DIN 2 Inch Wafer Butterfly Valve PN1.0/1.6Mpa Pinless Cast Iron
API/ DIN Standard/ Cast Iron Material/ PN1.0/ PN1.6Mpa Pinless Wafer Butterfly Valve
Introduce
The butterfly plate of the handle 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 with a rotation angle of 0 ° - 90 °. When it rotates to 90 °, the valve is fully open. This valve is generally installed horizontally
