D373H, D373Y type butterfly valve adopts precise J-shaped elastic sealing ring and three eccentric multi-level metal hard sealing structure, is widely used in the medium temperature ≤425℃ gold, electric power, petrochemical industry, and water supply and drainage and municipal construction and other industrial pipelines, for regulating flow and load cut-off body use.

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

2. The sealing ring is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. Regardless of low temperature and high temperature, it has excellent sealing performance, corrosion resistance, long service life and so on.

3, the sealing face of the butterfly plate is surfacing cobalt-based carbide, the sealing face is resistant to wear and has long service life;

4, large size butterfly plate adopts quilted structure, high strength, large flow area, small flow resistance;

5, the clip-type hard seal butterfly valve has a two-way sealing function, installation is not restricted by the medium flow direction, is not affected by the spatial location, can be installed in any direction;

6, the drive device can be installed in multiple stations (rotation 90° or 180°), easy to use.
