Product Description

Product characteristics

1, the valve adopts double eccentric structure, with the sealing function of the closer and tighter, the sealing performance is reliable.
2, the sealing auxiliary material selection of stainless steel and nitrile oil resistant rubber pairing, long service life.
3, the rubber sealing ring can be located on the valve body, can also be located on the butterfly plate, can be applicable to different characteristics of the media, for the user to choose.
4, the butterfly plate adopts the frame structure, high strength, large flow area, small flow resistance.
5, the whole paint, can effectively prevent rust and as long as the replacement of the sealing valve seat sealing material, you can be used in different media.
6, the valve has a two-way sealing function, the installation is not controlled by the flow of the medium, is not affected by the spatial position, can be installed in any direction.
7. The valve has unique structure, flexible operation, labor-saving and convenient.
