Structure features and applications: on the basis of introduction of foreign advanced technology, our factory adopt precision J shape seal and triple eccentric metal hard seal structure, widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction and other industrial pipelines, used to adjust flow and cut off fluid. It adopts three eccentric structures, valve seat and disc plate sealing surface made of different hardness and stainless steel, it has good corrosion resistance, long service life, the products comply with the national GB/T13927-92 valve pressure test standard. 

1, the valve adopts triple eccentric sealing structure, the seat and disc almost have no wear and tear, with the function of more and more tight seal.

2, sealing ring made of stainless steel, has the dual advantages of metal hard seal and elastic sealing, no matter in the case of low or high temperature, has excellent sealing performance, corrosion resistance, long service life,etc.

3, butterfly plate sealing surface uses cobalt-based cemented carbide, sealing surface with wear resistance, long service life.

4, large size butterfly plate adopts the structure of supporting structure, with high intensity, large flow area, and small flow resistance.

5, drive device can transfer (rotated 90 ° or 180 °) in installation, making it easy for users to use.
