PRODUCT OVERVIEW
Lift-down fluorine-lined check valve is also called check valve. The internal flow channel seal of the valve body is fully lined with tetrafluoride, which has high strength and good corrosion resistance. It is suitable for Aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidizers in various concentrations from -50 ~150 C. FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive gases and liquids.On the pipeline of a medium, used to prevent backflow of the medium.
