The lifting type fluorine-lined check valve is also called a non-return valve. The internal flow channel seal of the valve body is fully lined with PTFE, which has the characteristics of high strength and good corrosion resistance. It is suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, and strong oxidants at -50℃~150℃. FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive gases and liquid media on the pipeline to prevent the backflow of the medium.
