MANUAL FABRICATED DAMPER BUTTERFLY VALVE DOUBLE FLANGED END
“aline” Make Manual Fabricated Damper Butterfly Valve – Double Flanged End is specially engineered for reliable flow isolation and regulation in air, flue gas, exhaust gas, dust collection, ventilation, and low-pressure industrial process applications. Fabricated from high-quality steel plates and precision-machined components, this valve offers excellent strength, lightweight construction, and dependable performance in large-diameter pipeline systems.
The double flanged end design provides secure and leak-resistant installation between pipeline flanges while ensuring excellent structural stability. Operated through a robust manual lever or gear mechanism (as per application), the fabricated damper valve allows smooth opening and closing with low operating torque. Its rugged fabricated construction makes it ideal for handling high-temperature gases, dusty media, and corrosive industrial environments.
Designed for durability and easy maintenance, the ALINE Fabricated Damper Butterfly Valve is widely used in Power Plants, Cement Plants, Steel Industries, Chemical Plants, Boilers, HVAC Systems, Dust Collection Systems, Pollution Control Equipment, FGD Systems, Mining, Paper Mills, and Process Industries where reliable airflow and gas control are essential.
Manufactured with precision engineering and quality materials, ALINE Fabricated Damper Butterfly Valves ensure long service life, low maintenance, and efficient flow control even under demanding operating conditions.
