Structural features

Diaphragm valve is a special type of stop valve:

1. The opening and closing parts with elastic seal ensure no internal leakage;

2. Streamlined flow channel, making the pressure loss small;

3. There is no stuffing box, so there is no leakage;

4. The valve body and cover are separated by the middle diaphragm, so that the valve cover, valve rod and other parts above the diaphragm are not eroded by the medium;

5. The diaphragm can be replaced and the maintenance cost is low;

6. The diversity of lining materials can be applied to various media, and has the characteristics of high strength and good corrosion resistance.

Eg6b41j pneumatic normally closed rubber lined diaphragm valve, eg6b41j-10 and eg6b41j-6 rubber lined valves are used to change the channel section and medium flow direction, and have the functions of diversion, cut-off, regulation, throttling, check, diversion or overflow. Valves can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluids.
