Double-Flanged ANSI 150lb Butterfly Valve with PTFE Seat for Chemical Service

The VESON Double-Flanged ANSI 150lb Butterfly Valve with PTFE seat is purpose-built for chemical processing applications requiring full corrosion resistance. The double-flanged body design enables easy installation and removal from the pipeline, while the PTFE seat and PFA-lined disc provide universal chemical compatibility for aggressive acids, solvents, and corrosive media.
