Product Description

Product overview

Precision J-shaped elastic seal ring and three eccentric multi-level metal hard seal structure, is widely used in medium temperature ≤425ºC metallurgy, electric power, petrochemical, water supply and drainage and municipal construction and other industrial pipelines, for regulating flow and load body use. 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 mil-itary seal function, the product conforms to the national GB/T13927-92 valve pressure test standard.

Product 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, regardless of low temperature and high temperature, it has excellent sealing performance, corrosion resistance, long service life and other characteristics.
3. The sealing surface of the plate is surfacing cobalt-based cemented carbide, which is wear-resistant and has a long service life.
4, large specifications of the plate quilted structure, high strength, large flow area, small flow resistance.
5, 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.
6, the drive device can be multi-station (rotation 90° or 180°) installation, easy for users to use.
