PTFE Wafer Type Butterfly Valve

ALIS Valves offers PTFE Wafer Type Butterfly Valves for industrial applications requiring reliable flow isolation, corrosion resistance and compact installation in pipeline systems. These valves feature a rotating butterfly disc and a PTFE (Polytetrafluoroethylene) seat or lining, depending on the design, to provide a chemically resistant sealing surface for compatible process media. The wafer-style body is designed to fit between matching pipeline flanges and is secured using the specified bolting arrangement, making it suitable for installations where space efficiency is important. The PTFE components help protect selected valve surfaces from corrosive fluids and support dependable sealing within the valve’s rated operating limits. Depending on the application, these valves can be supplied with manual, pneumatic or electric actuation to meet different operational and automation requirements.

PTFE Wafer Type Butterfly Valves are used in chemical processing plants, pharmaceutical facilities, acid and alkali handling systems, water treatment installations and other industries involving compatible corrosive fluids. They can be specified for suitable 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 compatibility, pressure rating, operating temperature, chemical compatibility, body and disc materials, seat design, required leakage performance and actuator specifications. PTFE offers broad chemical resistance, but its pressure-temperature limitations and compatibility with the actual process media must be evaluated carefully. Buyers should also verify the required flange dimensions and installation standards before selection. Choosing the appropriate valve configuration helps support dependable sealing, corrosion resistance and reliable performance under the intended operating conditions.
