Structural features

Three-way diaphragm valve is a special form of stop valve;
1, the opening and closing parts of the elastic seal to ensure that there is no internal leakage;
2, streamlined flow path, so that the pressure loss is small;
3, no stuffing box, so there is no leakage;
4, the valve body and the cover are separated by the middle diaphragm, so that the valve cover above the diaphragm and the stem parts are not eroded by the medium;
5, the diaphragm can be replaced, low maintenance costs;
6, the diversity of lining materials, can be applied to a variety of media, and has good corrosion resistance.
