PTFE Double Flanged Butterfly Valve

flow control, corrosion resistance and dependable isolation in chemically demanding environments. These valves feature a rotating butterfly disc and a PTFE (Polytetrafluoroethylene) seat or liner, depending on the design, to provide a chemically resistant sealing surface for compatible process media. The double-flanged body incorporates flanges at both ends, allowing secure bolted connections to matching pipeline flanges and supporting stable installation in industrial piping systems. The PTFE seating arrangement helps reduce direct contact between the process media and selected valve components, while the disc rotation enables the flow passage to be opened, closed or regulated. Depending on the specified configuration, these valves can be supplied with manual, pneumatic or electric actuators to suit different operating and automation requirements.

PTFE Double Flanged Butterfly Valves are used in chemical processing plants, pharmaceutical facilities, acid and alkali handling systems, water treatment installations and other industries involving corrosive fluids. They can be specified for compatible acids, alkalis, chemical solutions and other process media within the pressure and temperature limits of the selected PTFE components and valve construction. Important selection factors include valve size, flange standard, pressure rating, operating temperature, chemical compatibility, body and disc materials, seat design, leakage requirements and actuator specifications. PTFE offers broad chemical resistance, but its pressure and temperature capabilities must be evaluated for the actual service conditions. Buyers should also confirm the required flange dimensions and installation standards before selection. Choosing the appropriate valve configuration helps support reliable sealing, corrosion resistance and consistent performance throughout the intended operating range.
