Three eccentric hard seal butterfly valve adopts three eccentric structure, the valve seat and disc plate sealing surface are made of different hardness and stainless steel, with two-way sealing function, the product conforms to the national GB/T13927-92 valve pressure test standard. Therefore, it is widely used in the medium Temperature≤425 ℃ gold, electric power, petrochemical, and water supply and drainage and municipal construction and other industrial pipelines, for regulating the flow and carrying off the fluid use.

Three eccentric butt clip hard seal butterfly valve closes, the sealing ratio pressure between the two sealing surfaces of the sealing vice not only eliminates the conventional eccentric butterfly valve sealing ratio pressure reduction and disappearance, but also change the external driving torque to realize the sealing ratio pressure of its arbitrary adjustment, so it is widely used in medium temperature ≤ 425 ° C in the treatment of gold, electric power, petrochemical industry, as well as drainage and municipal construction of the industrial pipeline.

Three eccentric hard seal butterfly valve clamped and flange type, sealing form more sealing structure, sealing material for rubber, PTFE and so on. The operation mode is manual, worm gear, electric and other operation modes. Three eccentric hard seal butterfly valve due to the limitation of structural characteristics, not adapt to high temperature, high pressure and corrosion resistance, anti-wear and other industries. It is suitable for pipeline system through and through and pipeline flow control, widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields.
