ProductName：Metal hard sealing ball valve 

ProductNumber：HL3D000

Metal hard sealing ball valve

 Metal hard sealing valve, adopting wholly metal proof structure with certain indurations technology on the surface of sealing, meets the special requirements of granular medium, long life, hard wearing, and zero leakage and so on, which is fit for high temperature and high pressure environment.

    I. Indurations treatment on the Surface of Sealing

    It is lacquered by the Tungsten Carbide, Chromium carbide or Stellite with the indurations treatment to the balls and seats according to certain working conditions, in order to make them meet the special requirements of high temperature and high pressure, granular medium, long life and hard wearing.

    II. High Sealing Level

    The level of sealing reaches the standard of ANSIⅥ, as the sealing performance is guaranteed by the spring-loaded pre-tensional structure and special grind process.

     It’s bi-directional sealing structure without require of flow direction.

    III. Long life

    with the treatment of indurations on the surface of sealing, it guarantees the long life of the sealing performance.
