A wafer PTFE seat butterfly valve is a type of butterfly valve that uses a wafer-style body design with a polytetrafluoroethylene (PTFE) seat. This valve is used to regulate or control the flow of various types of liquids, gases, and slurries in a variety of industries, including chemical processing, water treatment, and food and beverage production. The PTFE seat provides excellent chemical resistance, high-temperature tolerance, and low friction, making it an ideal material for use in harsh environments with corrosive or abrasive substances. The wafer design allows for easy installation and removal of the valve, and the butterfly disc provides a low-profile design that minimizes turbulence and pressure drop in the pipeline.
