D343H hard seal flange butterfly valve adopts precise J-shaped elastic sealing ring and three eccentric multi-layer metal hard seal structure, is widely used in the medium temperature ≤ 325 ℃ of the gold, electric power, petrochemical industry, as well as drainage and municipal construction and other industrial pipelines, for regulating the flow rate and cut off the fluid use.
Product Features
- This valve employs a triple-eccentric sealing structure, featuring virtually no wear between the seat and disc. It exhibits a self-tightening sealing function that becomes tighter over time.
- The sealing ring is made of stainless steel, combining the dual advantages of a metal hard seal and an elastic seal. It delivers excellent sealing performance under both low and high temperatures, featuring corrosion resistance and a long service life.
- The disc plate sealing surface is overlaid with cobalt-based hard alloy, ensuring wear resistance and extended service life.
- Large-sized butterfly valves feature a truss structure, offering high strength, large flow area, and low flow resistance.
