Chemoil Advance Technology supplies PFA / PTFE Lined Concentric Butterfly Valves from recognized manufacturers for reliable flow isolation and control in applications involving corrosive and chemically aggressive process media. The combination of a concentric butterfly valve design with PFA or PTFE lining provides a corrosion-resistant wetted surface when the selected lining is compatible with the process conditions.

The concentric butterfly design uses a centrally positioned disc and shaft arrangement to provide compact quarter-turn operation. The fluoropolymer lining creates a protective barrier between the process medium and the valve's pressure-containing components, helping reduce direct exposure of the body to corrosive chemicals.
