G45j direct flow rubber lined diaphragm valve product overview

Applicable temperature of direct flow rubber lined diaphragm valve: ≤ 85 ℃ applicable medium: corrosive sealing ring material selection: natural rubber, neoprene rubber, nitrile rubber, butyl rubber, fluoroplastic, EPDM rubber. G45j DC rubber lined diaphragm valve is mainly used to change the channel section and medium flow direction, and has 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. G45j rubber lined diaphragm valve is a special type of valve with cut-off function. Its closing part is composed of a diaphragm made of steel valve disc and soft materials (rubber and fluoroplastic composite), and separates the inner cavity of the valve body from the inner cavity of the bonnet, so as to achieve the purpose of cutting off the medium in the pipe.

Structural characteristics of g45j direct flow rubber lined diaphragm valve

DC rubber lined 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.
