Detailed Product Description

manual-operated wafer butterfly valve .

1, this valve use double eccentric structure, with the more tightly sealed off the more features, sealing and reliable performance.

2, Sealing materials, use stainless steel and nitrile rubber match, long service life.

3, rubber seals can be located on the valve body can also be located on butterfly board, applicable to the different characteristics of the medium for users to choose.

4, butterfly plate with frame structure, high strength, over-current area, a small flow resistance.

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

6, the valve has a bi-directional sealing capabilities, installation, without the control of media flows, but also from the impact of spatial location can be installed in any direction.

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