The Teflon Lined Plug Valves (full lining type) and Bushing Stopcock (semi-lining type) are designed for controlling the flow of medium and for medium distribution, such as in three-way stopcocks. These plug valves are primarily used for shutting off the flow of media. The fluorine lining is suitable for handling various concentrations of water, sulfuric acid, hydrochloric acid, hydrofluoric acid, and a wide range of organic acids, strong acids, and strong oxidizing agents at temperatures from -29°C to +180°C. FEP lining is also suitable for use with strong alkaline organic solvents and other corrosive gases and liquids.
