Characteristic：
1, the valve uses three eccentric seal structure, the valve seat and the butterfly plate almost no wear, with more view of the tight sealing function.
2, the sealing ring is made of stainless steel, has the dual advantages of ametal sealandsealthe, both in low and high temperature conditions, both with excellent sealing performance, corrosion resistant, long service life etc..
3, the disc sealing surface using cobalt based alloy welding, sealing surface wear resistance, long service life
4, large formatdiscusinglatticestructure, high strength, large flow area, flow resistance is small.
5, the valve has a two-way sealing function, the installation is not limited by the flow of media, and is not affected by the location of space, can be installed in any direction.
6, the driver can be multi station (rotating 90 degrees or 180 degrees) installation, user-friendly.
