PNEUMATIC ACTUATOR OPERATED DAMPER BUTTERFLY VALVE DOUBLE FLANGED END
“aline” Make Pneumatic Actuator Operated Fabricated Damper Butterfly Valve – Double Flanged End is specifically designed for airflow control, isolation, and regulation in industrial ducting systems, ventilation lines, and low-pressure process applications. Manufactured from heavy-duty fabricated steel construction, this valve offers excellent mechanical strength, lightweight design for large diameters, and superior durability in demanding operating environments.
Equipped with a high-performance rack & pinion pneumatic actuator, the valve provides fast, smooth, and reliable quarter-turn operation with minimal maintenance. The Double Flanged End design ensures rigid installation, accurate alignment, and secure sealing in large pipeline and ducting systems. It is widely used for controlling air, flue gas, exhaust gas, hot gas, dust-laden air, smoke, and other non-corrosive process media.
