PNEUMATIC ACTUATOR OPERATED “FEP LINED” & “PFA LINED” BUTTERFLY VALVE WAFER TYPE
“aline” Make Pneumatic Actuator Operated PFA Lined / FEP Lined Butterfly Valve – Wafer Type Class 150 is specially engineered for highly corrosive, aggressive, and high-purity chemical applications where conventional butterfly valves are unsuitable. The valve features a PFA (Perfluoroalkoxy) or FEP (Fluorinated Ethylene Propylene) lined body and disc, providing outstanding resistance to corrosive chemicals, acids, alkalis, solvents, and oxidizing media while ensuring excellent sealing performance and long service life.
The valve is equipped with a high-performance rack & pinion pneumatic actuator, delivering fast, reliable, and maintenance-free quarter-turn automation. The Wafer Type body is compact, lightweight, and designed for installation between ANSI Class 150 flanges, making it an ideal solution for chemical processing, pharmaceutical plants, fertilizer industries, water treatment, and other demanding industrial applications.
