Structural characteristics:

1, hard seal butterfly valve uses three eccentric hard seal structure, seat and disc almost no wear, with more tightening of the sealing function concept.

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 size disc using lattice structure, high strength, large flow area, flow resistance is small.

5, according to the user demand, hard seal butterfly valves supply network can be designed with two-way sealing function, the installation media flows from the restrictions, it is not affected by the spatial location, can be installed in any direction.

6, the driving device can multi-station (rotated 90 ° or 180 °) installation, user-friendly
