2. Product features
Diaphragm valve is a special form of shut-off valve:
1. The opening and closing parts of the elastic seal ensure that there is no internal leakage;
2. The streamlined flow channel makes the pressure loss small;
3. There is 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, valve stem and other parts above the diaphragm are not corroded by the medium;
5. The diaphragm can be replaced and the maintenance cost is low;
6. The variety of lining materials can be applied to various media, and has the characteristics of high strength and good corrosion resistance.
