Product Description

D373H Clamp metal hard seal butterfly valve overview

On the basis of the introduction of foreign advanced technology, the company adopts precision J-shaped elastic sealing ring and three-eccentric multi-level metal hard seal structure, which is widely used in the medium temperature ≤425ºC gold, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines to adjust the flow and load stopper body. The valve adopts three eccentric structure, the valve seat and plate sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the valve mili-tary seal function, the product conforms to the national GB/T13927-92 valve pressure test standard.

D373H clamp type metal hard seal butterfly valve features

1, the valve adopts three eccentric sealing structure, the valve seat and the butterfly plate almost no wear, with more and more tight sealing function.
2, the sealing ring is made of stainless steel, with the double advantages of metal hard seal and elastic seal, no matter in the case of low temperature and high temperature, has excellent
3, the sealing performance, with corrosion resistance, long service life and other characteristics.
4. The sealing surface of the plate is surfacing cobalt-based cemented carbide, which is wear-resistant and has long service life.
5, large specifications of the plate quilted structure, high strength, large flow area, small flow resistance.
6, the valve has a two-way sealing function, the installation is not limited by the flow of the medium, is not affected by the spatial position, can be installed in any direction.
7, the dynamic device can be installed in multiple stations (rotation 90° or 180°), which is easy for users to use.
