    FAQs

    What is a Lined ptfe pfa butterfly valve?

    A Lined PTFE (Polytetrafluoroethylene) PFA (Perfluoroalkoxy) butterfly valve is a high-performance control device engineered to provide superior resistance against corrosive media and extreme temperatures. Tailored for demanding applications, this type of valve is characterized by its robust construction where the internal components, particularly the disc and the body, are lined with PTFE or PFA. These fluoropolymers are praised for their excellent chemical stability and low friction properties, which result in minimal wear and longevity of service life under harsh operating conditions.

    In the architecture of a Lined PTFE PFA butterfly valve, the disc is designed to rotate within the lined valve body to regulate or halt fluid flow. The use of PTFE and PFA linings ensures a near-universal chemical compatibility, making these valves ideal for handling aggressive chemicals, solvents, and other substances that could degrade standard materials. Furthermore, the linings contribute to a tight seal, reducing the risk of leaks—a critical consideration in stringent process environments.
