【Product Usage】

【Features】

1. The high-performance wafer butterfly valve adopts a three-eccentric sealing 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 dual advantages of metal hard seal and elastic seal. 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, and the sealing surface is wear-resistant and has a long service life.

4. Large size butterfly board adopts quilt structure, high strength, large flow area and small flow resistance

5. Wafer type hard-sealed butterfly valve has a bidirectional 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.

6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °), which is convenient for users to use
