MANUAL DAMPER BUTTERFLY VALVEWAFER TYPE
“aline” Make Manual Damper Butterfly Valve – Wafer Type is specifically designed for air handling, ventilation, dust collection, flue gas, and low-pressure industrial applications where smooth flow regulation and reliable shut-off are required. Engineered with a lightweight wafer-type body and precision damper disc, this valve provides excellent airflow control, low operating torque, and long service life.
The wafer-type construction allows easy installation between standard flanges while minimizing space requirements and overall system weight. Operated through a manual lever handle with locking mechanism, the valve provides quick 90° quarter-turn operation for accurate flow balancing and isolation.
Manufactured using premium-quality materials such as Carbon Steel, Stainless Steel, Mild Steel, Ductile Iron, and Aluminum, the ALINE Damper Butterfly Valve offers excellent durability and corrosion resistance for air, gases, smoke, dust-laden air, and non-corrosive industrial media.
This valve is widely used in HVAC Systems, Cement Plants, Power Plants, Steel Industries, Boiler Systems, Dust Collection Units, Fume Extraction Systems, Ventilation Ducts, Pollution Control Equipment, Chemical Plants, and General Industrial Air Handling Applications.
Designed for dependable performance, easy maintenance, and long operational life, ALINE Manual Damper Butterfly Valves deliver efficient airflow control in demanding industrial environments.
