The internal cavity surface of the EG6B41J normally closed British standard rubber-lined pneumatic diaphragm valve has a variety of rubbers to choose from. Therefore, it has superior corrosion resistance. Because the flow path of the diaphragm valve is smooth and the flow resistance is small, a larger flow rate can be obtained.

Structural features:

Diaphragm valve is a special form of shut-off valve:
1. The opening and closing parts with elastic sealing 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.

EG6B41J pneumatic normally closed rubber-lined diaphragm valve, EG6B41J-10, EG6B41J-6 type rubber-lined valve is used to change the passage section and the flow direction of the medium, with diversion, cut-off, adjustment, throttling, check, diversion or overflow And other functions. Valves can be used to control the flow of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals, and radioactive fluids.
