Structural characteristics of
1, the valve adopts double eccentric structure, with more and more tight sealing function, sealing performance is reliable.
2. The sealing materials are matched with stainless steel and nitrile oil-resistant rubber for long service life.
3, rubber sealing ring can be located on the valve body, can also be located on the butterfly board, can be suitable for different characteristics of the media, for the user to choose.
4. Butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.
5, the overall baking paint, can effectively prevent corrosion and as long as the replacement of sealing seat sealing material, can be used in different media.
6, the valve has a two-way sealing function, installation is not subject to the direction of control of the medium, nor affected by the space position, can be installed in any direction.
7, the valve unique structure, flexible operation, labor-saving, convenient
