Welded Butterfly Valve Pneumatic/Electric Welded Butterfly Valve
Pneumatic/electric welded butterfly valve
D961H electric welding butterfly valve and pneumatic welding butterfly valve are suitable for use as opening and closing or regulating media on pipelines with high temperature, high pressure, fire resistance, insulation, etc. The use of precision J-shaped elastic sealing rings and three-layer metal hard sealing structures is widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃, for regulating flow and carrying fluids. The valve adopts a three component structure, and the sealing surfaces of the valve seat and disc plate are made of different hardness and stainless steel, which has good corrosion resistance and long service life. This valve has bidirectional sealing function.
