What is PTFE Lined Butterfly Valve?

A PTFE Coated Butterfly Valve is a butterfly valve that has a lining of a layer of PTFE (Polytetrafluoroethylene), FEP (Fluorinated Ethylene Propylene), or PFA (Perfluoroalkoxy) for increased chemical resistance. The lining shields the valve from corrosion, wear, and chemicals in harsh environments, thus suitable for handling highly corrosive fluids in chemical processing, pharmaceuticals, and food processing industries. It provides consistent sealing and increased durability, providing efficient fluid control in harsh environments.
