Flange sealing butterfly valve features: 1 the design is novel, the full size is small, light weight. 2 disc adopts double eccentric, opening and closing fast. 3 operating light energy saving no sliding friction between the butterfly plate and the sealing ring. Sealing surface wear resistance, long service life. Sealing is reliable, easy to adjust the four applicable medium water, sewage, urban water supply, heating, steam, gas, oil, acid and alkali, pipes, etc. Is widely used in metallurgy, light industry, electric power, petrochemical industry system of gas and water pipe flange hard of butterfly valve features: 1 disc and seal for the hard and soft cascading sheet metal, has the dual advantages of metal hard seal and elastic sealing, no matter in the case of low and high temperature, has excellent sealing performance. 2 adopts three-dimensional eccentric structure, the seat and disc almost no friction, with the more and more tightly seal function 3 valve sealing surface of surfacing welding stainless steel, cobalt base carbide, sealing surface and wear and long service life. 4 unique structure, flexible operation, energy saving, convenient and not affected by medium pressure high, low, sealed performance is reliable. 5 suitable medium water, sewage, urban water supply, heating, steam, gas, oil, acid and alkali, pipes, etc. Widely used in petroleum, petrochemical, metallurgy, electric power and other fields, is a good alternative for gate valve, globe valve products
