New chemically resistant Type 567 and 568 butterfly valves are available in large diameter sizes up to 8 or 12 in., depending on the model. The valves feature a disc and liner made of polyvinylidene fluoride (PVDF) and polytetrafluorethylene (PTFE) seals to provide superior chemical resistance and performance capabilities across a wide temperature range. By combing the two high-performance plastics of PVDF and PTFE, the valves provide low permeability and high chemical resistance for conveying extremely aggressive media.
