GTL-D371X Wafer Soft Sealing Butterfly Valve

Our company developed the soft seal middle line wafer butterfly valve, double eccentric flange butterfly valve compact structure, 90° rotary switch easy, reliable seal, long service life, is widely used in water plants, power plants, steel mills, paper making, chemical, food and other systems in water supply and drainage, as regulation and cut-off use.

Characteristics:

1. The valve adopts double eccentric structure, with more close more tight sealing function, reliable sealing performance.

2. The sealing deputy material selection of stainless steel and nitrile oil resistant rubber pair, long service life.

3. Rubber sealing ring can be located on the valve body, can also be located on the butterfly plate, can be applied to different characteristics of the medium, for users to choose.

4. Butterfly plate adopts frame structure, high strength, large flow area, small flow resistance.

5. The whole 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 media, is not affected by the space position, can be installed in any direction.

7. The valve has unique structure, flexible operation, labor-saving and convenient.
