PTFE Lined Butterfly Valve is a type of valve that has a disc that turns to allow or stop the flow of fluid, with PTFE (Polytetrafluoroethylene) lining inside the valve body and in the valve disc. The lining offers great chemical resistance, making it good for use within industrial processes and piping systems using very aggressive and corrosive fluids like many chemical and pharmaceutical processes. The PTFE lining allows for smoother operation by reducing friction reducing operating temperatures and allowing for a better seal leak proof to minimize leaks and improve durability by protecting the metal parts from corrosion and allowing the wear and for reliable and long-lasting repetitive use in harsh environments.
