Electric Wafer Hard Seal Butterfly Valves for three eccentric multi-level metal hard sealing structure, the use of a "U" shaped stainless steel ring, the precision of elastomeric seals in contact with the polished three-dimensional eccentric disc. Electric Butterfly Valve solve the traditional butterfly valve in the headstock 0 Ã?Â° ~ 10 Ã?Â° instant sealing surfaces in sliding contact friction still shortcomings and realize the disc sealing surface in the opening moments that separate the effect of close contact that is sealed, to prolong life, the best sealing performance purposes. Therefore, the German electric double seal butterfly valve is widely applied to the pipe medium temperature ≤550 ℃ metallurgy, electric power, petroleum, chemical, air, gas, flammable gas, and water supply and drainage and other corrosive media. Electric hard sealing butterfly valve regulating the flow of fluid and best device truncated.
