1. Product overview

Flange soft seal butterfly valve compact structure, easy 90° rotary switch, reliable sealing, long service life, is widely used in water plants, power plants, steel mills, paper, chemical, food and other systems in the water supply and drainage, as the regulation and cut-off use.

2. Product features

1, the valve adopts double eccentric structure, with more closed more tight sealing function, sealing performance is reliable.

2. The sealing pair is made of stainless steel and nitrile oil-resistant rubber for long service life.

3, rubber seal ring can be located on the valve body, can also be located on the butterfly plate, can be applied to different characteristics of the media, for the user to choose.

4. The butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.

5, the overall paint, can effectively prevent corrosion and as long as the replacement of sealing valve seat sealing material, can be used in different media.

6, the valve has a two-way sealing function, installation is not controlled by the flow of the medium, nor by the impact of the space position, can be installed in any direction.

7, the unique structure of the valve, flexible operation, labor saving, convenient.
