MANUAL LEVER OPERATED OFFSET DISC BUTTERFLY VALVE WAFER TYPE
“aline” Make Manual Lever Operated Offset Disc Butterfly Valve – Wafer Type is designed for reliable shut-off and flow control in demanding industrial applications. Featuring an offset disc design, the valve minimizes seat wear by reducing friction between the disc and seat during operation, resulting in longer service life, lower operating torque, and superior sealing performance.
The wafer-type body is compact and lightweight, allowing easy installation between standard flanges while reducing pipeline weight and installation costs. Operated through a manual lever handle with locking mechanism, the valve offers quick 90° quarter-turn operation and precise flow control.
Manufactured from premium materials such as Carbon Steel, Stainless Steel, Duplex Stainless Steel, and high-performance sealing materials, the ALINE Offset Disc Butterfly Valve is suitable for handling steam, gases, water, chemicals, oils, hydrocarbons, and various industrial process media under high-temperature and high-pressure conditions.
This valve is widely used in Chemical Plants, Petrochemical Industries, Oil & Gas, Power Plants, Water Treatment Systems, HVAC, Steel Plants, Cement Industries, Marine Applications, Food Processing, Pharmaceutical Industries, and General Industrial Process Pipelines.
Designed for durability, leak-tight sealing, and minimal maintenance, ALINE Offset Disc Butterfly Valves provide outstanding performance in both isolation and throttling applications.
