Description
The single-seat fluorine lined control valve features a full ptfe lined body and trim structure to effectively combat the corrosion caused by aggressive media. The metal body cavity receives serrated machining to allow lining materials to bond perfectly with the metal which extends both the lifespan and operational effectiveness of the lining. The stem seal consists of an F46 bellows seal combined with V type PTFE packing which provides complete protection against external environment leakage. The unbalanced full lined control valve serves as the best option for extremely corrosive media applications under low-pressure and ambient temperature conditions.

FAQs
What is PTFE lined control valves?
PTFE lined control valves serve as specialized valve systems which control the flow of highly corrosive or aggressive fluids in industrial processes. The synthetic fluoropolymer polytetrafluoroethylene (PTFE) demonstrates outstanding chemical resistance together with low friction properties and non-reactive behavior. The demanding operational requirements of control valves in chemical processing plants and pharmaceutical manufacturing and petrochemical industries make PTFE an ideal lining material because of its exceptional properties.
What industries are fluorine-lined control valves used in?
PTFE lined control valves are industrial valves that are specifically designed to handle extremely corrosive substances such as sulfuric acid, salt sulfur, and alkali. These fluorine-lined control valves are essential for industries dealing with chemical processing, petrochemicals, oil refining, and other similar fields where the handling of aggressive media is necessary.
