Triple Eccentric Flange Hard Seal Butterfly Valve
Triple eccentric flange hard seal butterfly valve adopts precision J elastic sealing ring and triple eccentric metal hard seal structure, multi-level is widely used in medium temperature of 400 ºC or less metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction and other industrial pipelines, used to adjust flow cutoff and body.
Characteristics:
1, The metal hard seal butterfly valve USES three eccentric sealing structure, the seat and the butterfly plate almost no wear, with the more tight sealing function.
2, The sealing ring is made of stainless steel, with metal hard seal and elastic seal double advantages, whether in low temperature and high temperature, have excellent sealing performance, corrosion resistance, long service life and other characteristics.
3. The sealing surface of butterfly plate is surfacing with cobalt-based hard alloy, which is resistant to wear and has a long service life.
4. Large size butterfly plate adopts quilted structure, with high strength, large flow area and small flow resistance.
5, The metal hard seal butterfly valve has a two-way sealing function, installation is not limited by the flow of the medium, nor affected by the space position, can be installed in any direction.
6, Driving device can transfer (rotate 90 ° or 180 °) installation, making it easy for users to use.
