PTFE Lined Valve

PTFE Lined Valve

PTFE Lined Valve refers to the lined valve which has taken the advantage of the properties of the PTFE. PTFE is a thermoplastic Fluoropolymer devised from carbon and Fluorine. In terms of the PTFE Lined Valve, the manufacturing material named the PTFE has done a lot of help for the practical performance.

PTFE has exceptional chemical stability, exceeding noble metal (goal and platinum), glass, ceramic enamel, special steel and special alloy. It can resist to various strong acids, strong alkalis, oxidants and organic solvents even at high temperature. It also has excellent thermal and electrical insulation properties. Its mechanical properties are low compared to other engineering plastics, but it remains at useful levels over a great temperature range (-200 to 260 oC). As well as, it is well-known that it has a very low coefficient of friction.

PTFE Lined Valve is a one-piece valve body and has pure-modified(reinforced) PTFE trim parts, push-down-to-close action, and positive shutoff. With sophisticated PTFE replaced the previously used glass-filled or carbon-filled standard PTFE trim without any loss of mechanical or thermal properties and having improved the universal chemical resistance, it has excellent performance. This valve is mainly applied to involving severely corrosive and toxic flowing media and is well-suited for pure media applications as well.
