Wafer Type Hard Seal Butterfly Valve

The wave type hard seal butterfly valve produced by milestone Industrial Co. Ltd. adopts stainless steel sealing ring. The elastic sealing ring has three eccentric contact with the butterfly plate, which realizes the effect of separating the sealing surface at the moment of opening and sealing at the moment of closing, so as to prolong the service life and achieve the best sealing performance. Therefore, wave type hard seal butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive medium pipelines with medium temperature ≤ 550 ℃. Wafer Type Hard Seal Butterfly Valve is the best device to regulate flow and cut off fluid.
