Fluorine lined valve, also known as fluorine plastic lined corrosion resistant valve, is the polytetrafluoroethylene resin PTFE or PFA(or profiles processed) by molding (or inlay) method placed on the inner wall of steel or iron valve pressure parts (the same method is suitable for all kinds of pressure vessels and pipeline accessories inside Liner) or the outer surface of the valve internals, using its unique performance in resistance to strong corrosive media to make all kinds of valves and pressure vessels.
Fluorine-lined valves can be used to reach the medium in the valve body all the lining process, the lining material is generally used FEP(F46) and PCTFE(F3) and other fluorine plastics, can be applied to various concentrations of hydrophobic acid, hydrochloric acid, hydrogen acid, aqua royal and various organic acids, strong acids, strong oxidants and other corrosive media pipelines. However, the fluorine lined valve is limited by temperature and is only suitable for medium between -50℃and 150℃.
