Customized Dn 100mm 125mm 150mm Cast Iron Rubber Lined Flanged Butterfly Valve
The closing part is a disc-shaped butterfly plate, and the valve
that rotates around a fixed shaft in the valve body to open, close
and regulate fluid is called butterfly valve.
The butterfly plate of rubber-lined 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 of the valve stem, and the rotation angle
is between 0 and 90 degrees. When it rotates to 90 degrees, the
valve is fully open.
The rubber lined flange batterfly valve should generally be
installed horizontally in the pipeline.

The use of rubber seat seal makes it suitable for lower temperature
and pressure, generally not more than 80℃ and not more than PN10,
but also makes it have very excellent sealing performance.
Therefore the rubber lined flange butterfly valve is most
suitable for normal temperature liquid.
