A fluoropolymer-lined plug valve is a valve that opens and closes by rotating a plug with a through hole. Its structure includes a fluoropolymer-lined steel valve body and plug, with the parts in contact with the medium lined with corrosion-resistant materials such as PFA or F46. This valve features rapid opening and closing, low fluid resistance, and can be operated manually, pneumatically, or electrically. It is suitable for pipelines carrying strong acids, strong alkalis, and corrosive media, and can withstand temperatures from -50℃ to 150℃.
According to design standards, it is divided into bushed type and fully lined type. The former uses a stainless steel plug with a polymer bushing for sealing, while the latter has all flow-through components lined.

Fluorine-Lined Plug Valve Features
- Corrosion Resistance: PTFE-lined plug valves are particularly suitable for corrosive media, such as aqua regia of various concentrations, sulfuric acid, hydrochloric acid, hydrofluoric acid, organic acids, strong alkalis, and other corrosive gases and liquids. This is due to the high-molecular materials used in the internal lining, such as F46 and F3, which effectively resist corrosion.
- Good Sealing Performance: Some models of PTFE-lined plug valves, such as the X43F/P, XD63F/R, and XC63F/R types, use a specially designed valve seat bushing (such as PTFE or para-polystyrene) and a steel plug body to form a sealing pair, resulting in good sealing performance and a long service life.
- Self-Lubricating and Flexible Rotation: Due to the excellent properties of the sealing material, PTFE-lined plug valves are self-lubricating during rotation, ensuring flexible rotation and reducing friction and wear.
