Cast Steel Teflon Lined Diaphragm Valve

The KOSEN Cast Steel Teflon Lined Diaphragm Valves is a special type of truncation valve. Its opening and closing is a diaphragm made of soft material. The inner cavity of the valve body is separated from the inner cavity of the valve cover and the driving part. The valve is characterized by the diaphragm separating the inner cavity of the lower body from the inner cavity of the upper valve cover, so that the valve rod and valve disc above the diaphragm are not corroded by the medium, and the packing seal structure is omitted and the medium leakage will not be produced.
