What is PTFE Lined Butterfly Valve?

A PTFE Coated Butterfly Valve is a butterfly valve coated with a layer of PTFE (Polytetrafluoroethylene), FEP (Fluorinated Ethylene Propylene), or PFA (Perfluoroalkoxy) for higher chemical resistance. The lining guards the valve from corrosion, wear and chemicals under aggressive conditions, rendering it suitable for processing highly corrosive fluids in chemical processing, pharmaceuticals, and food processing industries. It provides consistent sealing and superior durability, providing effective fluid control in harsh environments.
