Product Description
The Fluorine lined straight lift check valve is also called a check 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 temperatures of -50℃～150℃. FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosion products. It is used to prevent the backflow of the medium on the pipeline of the inert gas and liquid medium.
