Product Details

Butterfly Valve For Water



The soft sealing butterfly valve for water is composed of rubber seat, carbon steel or stainless steel valve plate and valve stem. It is suitable for regulating flow and intercepting media in water supply and drainage, gas pipelines such as food, medicine, chemical industry, petroleum, electric power, light textile, papermaking, etc. at temperatures ≤80~120℃. Here some feature as follows:

1. The water line design of the sealing valve seat and the plane design of the sealing surface of the valve plate completely avoid the jamming phenomenon of the pneumatic valve caused by a long time not opening.

2. At the upper and lower middle holes of the valve plate, the ball friction surface design is adopted, the torque is smaller, and the sealing performance is better.

3. The valve seat has no backrest design, the torque is lighter, and it is also convenient for users to replace the valve seat by themselves

4. A variety of standards are applicable to flange to clamp hole connection
