Pneumatic FEP/PFA Lug Type Butterfly Valve

ALIS Valves offers Pneumatic FEP/PFA Lug Type Butterfly Valves for industrial applications requiring automated flow control, corrosion resistance and reliable isolation of chemically aggressive media. These valves combine a butterfly disc mechanism with an FEP (Fluorinated Ethylene Propylene) or PFA (Perfluoroalkoxy Alkane) lining, depending on the specified design, to provide a chemically resistant barrier between the process media and the valve body. The lug-style body incorporates threaded lugs that allow secure bolting to compatible pipeline flanges. A pneumatic actuator uses compressed air to rotate the disc, enabling remote operation and integration with industrial automation systems. Depending on the valve configuration, the lining, disc, shaft seals and other wetted components can be selected to suit the chemical compatibility, pressure and temperature requirements of the application.

Pneumatic FEP/PFA Lug Type Butterfly Valves are suitable for chemical processing plants, acid and alkali handling systems, pharmaceutical facilities, specialty chemical production and water treatment installations involving compatible corrosive fluids. They can be specified for suitable chemical solutions and other process media within the pressure and temperature limits of the selected lining and valve construction. Important selection factors include chemical compatibility, valve size, pressure rating, operating temperature, lug and flange compatibility, lining material, actuator sizing, air supply pressure and required control function. FEP and PFA have different performance characteristics, so the appropriate lining should be selected according to the actual process conditions. Buyers should also confirm the required shut-off performance, actuator action and whether the valve is suitable for end-of-line service if needed. Selecting the correct valve and pneumatic actuator configuration helps support dependable automated operation, corrosion protection and consistent performance under specified working conditions.
