Structural features
1.The hard seal butterfly valve adopts a three-eccentric pure metal seal structure, the valve seat and the butterfly plate have almost no wear, and have a tighter sealing function.
2. The sealing ring is made of stainless steel, which has the advantages of metal hard sealing. It has excellent sealing performance under low and high temperature conditions, has the characteristics of corrosion resistance and long service life.
3. The sealing surface of the butterfly plate adopts surfacing cobalt-based hard alloy. The sealing surface is wear-resistant and has a long service life.
4. Large size butterfly board adopts quilt frame structure, high strength, large flow area and small flow resistance.
5. According to user needs, the hard sealing butterfly valve of the valve supply network can be designed to have a two-way sealing function. It is not restricted by the flow direction of the medium during installation, nor is it affected by the position of the space. It can be installed in any direction.
6. The driving device can be installed in multiple stations (rotation 90 ° or 180 °), which is convenient for users.
