6、 Structural characteristics of DC lined rubber diaphragm valve:

Diaphragm valve is a special form of globe valve;

1. Elastic sealed opening and closing components 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 and stem 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 have good corrosion resistance.
