Lined ball valve is a type of fluorine plastic lined corrosion-resistant ball valve, which lined fluorine resin (or by special processing) in steel or iron valve pressure bearing inner wall or the surface of inner parts bt the molding or injection process for strong corrosion medium. Simply put, the lining material needs to be filled in the valve body where the medium can reach. Fluorine lined ball valve can be used in all concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia and various organic acids, strong acids, strong oxidants, and other solid media, but is limited to temperature (for medium-range form -50℃to150℃). There are many fluorinated materials that can be used for lined ball valve. The most commonly used materials are FEP (F46) and PCTFE (F3). Today, we will introduce the characteristics and applications of these materials for you, if interested in, please read on!
