1, the valve adopts three eccentric sealing structure, seat and disc almost no wear, the concept of having more tight sealing function .
2, ring made of stainless steel production, with a metal seal and elastomeric seal the dual advantages, both in the case of low and high temperatures, has excellent sealing performance, corrosion resistance, long life and other characteristics .
3, the disc plate sealing surface using cobalt-based alloy welding, sealing surface wear resistance and long service life .
4, large-sized disc using lattice structure, high strength, flow area, flow resistance .
5, the valve has a two-way sealing function, the installation of unrestricted flow of medium, is not affected by spatial location can be installed in any direction.
6, the drive means may be multi-position (rotated 90 ° or 180 ° ) To install, easy to use.
