Fluorine-lined Valves Have Both The Strength Of Metal And The Corrosion Resistance

Lined Valve, also known as fluoroplastic lined corrosion-resistant valve, is a valve that uses a molding or inlay method to place polytetrafluoroethylene resin on the inner wall of a steel or iron valve pressure-bearing part or the outer surface of a valve trim, and uses its performance in resisting strong corrosive media to make various valves and pressure vessels.
Fluorine-lined valves are a lining process for all places in the valve body that the medium can reach. The lining material generally uses fluoroplastics such as FEP and PCTFE. It can be used for pipelines of various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, strong oxidants and other corrosive media, but fluorine-lined valves are relatively limited by temperature and cannot be used in high-temperature environments. There are many types of fluorine-lined valves, including fluorine-lined diaphragm valves, fluorine-lined stop valves, fluorine-lined ball valves, etc. Its manufacturing technology includes the formula of adhesives and their production process. The adhesive can make the lining glue have a strong affinity with the pipe wall, and has the advantages of superior corrosion resistance and anti-scaling performance and long service life. Therefore, fluorine-lined valves have both metal strength and corrosion resistance.
