Fully lined fluorine butterfly valve is a type of valve that uses a disc type opening and closing element to rotate back and forth about 90 degrees to open, close, and regulate fluid channels. The structure is simple, the volume is small, the weight is light, the material consumption is low, the installation size is small, the driving torque is small, the operation is simple and fast, and it also has good flow control function and closing sealing characteristics,

Three eccentric hard seal butterfly valve clamped and flange type, sealing form more sealing structure, sealing material for rubber, PTFE and so on. The operation mode is manual, worm gear, electric and other operation modes. Three eccentric hard seal butterfly valve due to the limitation of structural characteristics, not adapt to high temperature, high pressure and corrosion resistance, anti-wear and other industries. It is suitable for pipeline system through and through and pipeline flow control, widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields.

The fully lined fluorine butterfly valve is suitable for use in pipelines with various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and various organic acids, strong acids, and strong oxidants. It is also suitable for use in pipelines with various concentrations of strong alkaline organic solvents, as well as other corrosive gases and liquid media. It is to place polytetrafluoroethylene resin on the inner wall of steel or iron valve pressure parts or the outer surface of valve internals by molding embedding method.
