Electric hard seal flange butterfly valve
Simple introduction
D941H electric hard sealing flange butterfly valve adopts three partial hardness seal structure design, through strict calculation, "U" type sealing ring and butterfly plate almost no friction, solve the traditional eccentric butterfly valve in 0 ~ 10 degrees for opening and closing the disadvantages of seal face is still in the sliding contact friction moment be opened instantly sealing surface namely butterfly plate in the separation of close contact with the sealing effect and prolong the service life, sealed performance is the best.
The sealing surface of disc plate is made of hard gold based surfacing and drilling, and the sealing surface is resistant to wear. The butterfly plate of large size is made of spinning frame structure, featuring high strength, large flow area and small flow resistance，"Switch" only needs to turn stem 90°to complete.
Therefore electric hard seal butterfly valve is widely used in the medium temperature≤425℃metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage and other corrosive media pipeline, as the best device to regulate flow and cut off the fluid. Products in line with national GB/ t13927-92 valve pressure test standards.
