Diaphragm valve is a special form of cut-off valve;
1, elastic seal open and close parts, ensure no internal leakage;
2, streamlined runner, making the pressure loss small;
3, no stuffing, so no leakage;
4, the valve body and the cover is separated by the middle diaphragm, so that the diaphragm above the valve cover, stem and other parts from medium erosion;
5, diaphragm can be replaced, low maintenance costs;
6, lining material diversity, can be applied to various media, and has good corrosion resistance.
