Structural characteristics
Diaphragm valve is a special form of globe valve:
1. Elastic sealed opening and closing components to ensure no internal leakage;
2. The streamlined flow channel reduces pressure loss;
3. There is no stuffing box, so there is no leakage;
4. The valve body and cover are separated by a middle diaphragm, so that the valve cover, valve stem and other parts above the diaphragm are not corroded by the medium;
5. The diaphragm is replaceable and has low maintenance costs;
6. The diversity of lining materials can be applied to various media and has the characteristics of high strength and good corrosion resistance.
