The introduction of foreign advanced technology can be based on the J elastic precision ring and three eccentric multi-level metal seal structure, is widely used in medium temperature less than 425 DEG C, petroleum chemical industry, metallurgy, electric power and water supply and drainage and municipal construction and other industrial pipelines, for adjusting the flow and set off fluid. The three eccentric valve structure, valve seat and disc sealing surface are made of stainless steel with different hardness, good corrosion resistance, long service life, the two-way valve seal military postal function, valve product line with national GB/T13927-92 pressure test standard.
1, this valve adopts three eccentric sealing structure, seat and butterfly plate almost no wear, with sealing function.
2, the seal ring is made of stainless steel, with the dual advantages of metal hard seal and elastic seal, in the case of low and high temperature, have excellent sealing performance, corrosion resistance, long service life and other characteristics.
3. The sealing surface of the plate is hardfaced with cobalt-based carbide, which is resistant to wear and has a long service life.
4. Large size butterfly plate adopts the structure of quilting, with high strength, large flow area and small flow resistance.
5, the valve has a two-way sealing function, installation is not limited by the flow of the medium, nor by the impact of the space position, can be installed in any direction.
6. The driving device can be installed in multiple stations (rotating 90° or 180°), which is convenient for users to use.
