                D943H electric flange hard-sealed butterfly valve adopts precise J-shaped elastic seal ring and three-eccentric multi-layer metal hard-sealed structure. It is widely used in gold treatment, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines with medium temperature < 425 C for regulating flow and carrying and breaking off fluid. The valve is made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has two-way sealing function. The product meets the national GB / T13927-92 valve pressure test standard.


                Characteristic


                1. The valve adopts a three-eccentric sealing structure, the seat and butterfly plate almost no wear and tear, with the tighter sealing function.


                2. The sealing ring is made of stainless steel. It has the double advantages of hard metal sealing and elastic sealing. It has excellent sealing performance, corrosion resistance and long service life, no matter at low and high temperature.


                The 3. disc sealing surface is made of cobalt base cemented carbide, the sealing surface is wear resistant and has long service life.


                4. large size butterfly plates are made of quilted structure with high strength, large flow area and small flow resistance.


                5. The valve has two-way sealing function. It can be installed in any direction without the restriction of medium flow direction or the influence of space position.


                The 6. driving device can be installed at multiple stations (rotating 90 degrees or 180 degrees) for user convenience.
