Flange lined fluorine butterfly valve
D341F4 flange lined fluorine butterfly valve is a valve designed specifically for corrosive media. It is made of cast steel or stainless steel shell lined with polytetrafluoroethylene (F4/F46) material, and has characteristics such as acid and alkali resistance and high temperature resistance.
Structural Design
Worm gear transmission or manual operation, flange connection method, valve body and butterfly plate fully lined with fluorine to ensure zero medium leakage.
Using spherical sealing surface lined with fluorine butterfly plate, combined with silicone rubber gasket to adjust the sealing performance.
Applicable scenarios
Regulating or cutting off pipelines for highly corrosive media such as sulfuric acid, hydrofluoric acid, chlorine gas, etc.
Chemical, petroleum, sewage treatment and other industries.
