Product Usage
D373H, D373Y-type high-performance butterfly valve butterfly valve with precision J-shaped elastic ring and three eccentric multi-layer metal hard seal structure, is widely used in medium temperature ≤ 425 ℃ metallurgy, power, petrochemical, as well as water supply and municipal Construction and other industrial pipes, for regulating the flow and breaking the use of fluids.
Features
1. High-performance butterfly valve butterfly valve with three eccentric seal structure, valve seat and disc almost no wear, with the more the more tight sealing function
2. The seal ring made of stainless steel, with a metal seal and the advantages of flexible double seal, both in the case of low temperature and high temperature, have excellent sealing performance, corrosion resistance, long service life
3. The sealing surface of the disc welding cobalt-based hard alloy, wear-resistant sealing surface, long life
4. Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance
5. The folder-type hard-sealed butterfly valve with two-way sealing function, the installation is not limited by the flow of media, but also the location of space, can be installed in any direction
6. The drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly
