Performance:

1. The 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 frame structure, high strength, large flow area, small flow resistance

5. The wafer-type hard-sealed butterfly valve has 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 to use
