Teflon Lined Plug Valves (full lining type) and Bushing Stopcocks (semi-lining type) are designed primarily for medium flow shut-off and distribution (three-way stopcock). These valves are ideal for handling a wide range of corrosive media, including various concentrations of water, sulfuric acid, hydrochloric acid, hydrofluoric acid, and organic acids, as well as strong acids and oxidizing agents within the temperature range of -29°C to +180°C. The FEP lining is also suitable for strong alkaline organic solvents and other corrosive gas and liquid media.
