MANUAL CENTRIC DISC TYPE “PFA LINED & FEP LINED” BUTTERFLY VALVE WAFER TYPE
“aline” Make Manual Centric Disc Type “PFA Lined & FEP Lined” Butterfly Valve – Wafer Type is specially engineered for handling highly corrosive chemicals, acids, alkalis, solvents, and aggressive process media where superior chemical resistance and leak-free performance are essential. Designed with a centric disc configuration and PFA/FEP lined wetted parts, this butterfly valve provides exceptional corrosion resistance, bubble-tight sealing, low operating torque, and long-lasting performance even in the most demanding chemical processing environments.
The wafer-type body offers a compact and lightweight design, allowing easy installation between standard flanges while reducing piping space and installation costs. Operated through a manual lever handle with locking mechanism, the valve provides smooth 90° quarter-turn operation for reliable flow isolation and control.
Manufactured using high-quality Cast Iron, Ductile Iron, Carbon Steel, Stainless Steel, with PFA (Perfluoroalkoxy) and FEP (Fluorinated Ethylene Propylene) lining, the valve delivers outstanding resistance to corrosive fluids, ensuring long service life with minimal maintenance.
This valve is widely used in Chemical Industries, Pharmaceutical Plants, Petrochemical Industries, Fertilizer Plants, Acid & Alkali Handling Systems, Water Treatment Plants, Dye & Pigment Industries, Paper Mills, Food Processing Industries, and General Corrosive Process Applications.
Designed to meet demanding industrial requirements, ALINE PFA & FEP Lined Butterfly Valves ensure safe operation, excellent sealing performance, and dependable service in highly corrosive environments.
