PFA Lined Plug Valve, API 6D, ASTM A351 CF8, DN50, PN16, RF

Key Specifications / Features

The PFA Lined Plug Valve is designed in accordance with API 6D standards. These valves feature a stainless steel body made from ASTM A351 CF8, ensuring durability and corrosion resistance. The valves have a size of 2 inches (DN50) and are rated for PN16 (Class 150 LB). They are equipped with RF flanged ends for secure and reliable connections. The PFA lining provides excellent chemical resistance, making these valves suitable for applications involving aggressive media.

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.
