    Manual wafer soft seal butterfly valve This product consists of rubber seal butterfly valve, carbon steel or stainless steel valve plate and valve stem. Suitable for temperature ≤ 80~120 ℃, such as food, medicine, chemical industry, petroleum, electric power, textile, paper and other water supply and drainage, gas pipeline for regulating flow and intercepting medium. Its main features are: novel design, reasonable, unique structure, light weight, open and close quickly. Operating torque is small, easy to operate, labor-saving dexterity. Can be installed in any position, easy maintenance. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing and zero leakage. The sealing material has the characteristics of aging resistance, weak corrosion resistance and long service life.

    Manual wafer soft seal butterfly valve structure characteristics description;

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

    2, Sealing vice 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 or on the butterfly plate, which can be applied to media with different characteristics for users to choose.

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

    5, the overall paint, can effectively prevent corrosion and as long as the replacement of the sealing seat sealing material, 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, nor is it affected by the space position, can be installed in any direction.
