The Features of Hard Sealing Butterfly Valve

1. Hard sealing butterfly valve uses three-eccentric sealing structure. There’s no wear and tear for sanitary valve seat and butterfly plate, which have the sealing function of “the further it is closed, tighter”.

2. The sealing ring is made of stainless steel. It has the dual advantage of metal hard sealing and elastic sealing. Whether in low temperature or high temperature conditions, it has excellent sealing performance. It also has corrosion resistance, long service life and other features.

3. The sealing surface of the butterfly plate uses cobalt-welded hard alloy. The sealing surface has wear resistance and a long service life.

4. Large-format butterfly plate uses a frame structure, which has a high strength, a large flow area and a small flow resistance.

5. Hard sealing butterfly valve has a two-way sealing function. Its installation is not subject to the restrictions of the flow direction of the medium. Nor is it subject to the location. It can be installed in any direction.

6. The actuating device can be installed in various positions, which is easy for use.
