Fabricated Damper Butterfly Valve

ALIS Valves offers Fabricated Damper Butterfly Valves for industrial applications requiring efficient airflow regulation and control of gases in large ducts, ventilation networks and process systems. These valves feature a fabricated body and rotating butterfly disc designed to regulate the movement of air or compatible gases by adjusting the disc position. The fabricated construction allows the valve dimensions, body configuration, disc arrangement and material selection to be tailored to specific installation and process requirements. Depending on the application, suitable carbon steel, stainless steel or other compatible materials can be selected to accommodate the operating temperature, gas composition and environmental conditions. Manual, pneumatic or electric actuation options may be incorporated to support local operation, remote control or automated integration with industrial control systems.

Fabricated Damper Butterfly Valves are used in power plants, industrial furnaces, cement plants, steel manufacturing facilities, exhaust systems, dust collection equipment, HVAC installations and process gas handling applications. They are suitable for controlling airflow and compatible gases where the valve’s design ratings and sealing performance meet the system requirements. Important selection factors include duct dimensions, operating temperature, differential pressure, gas composition, flow capacity, body and disc materials, fabrication thickness, shaft arrangement, required leakage performance and actuator torque. Depending on the service, additional design considerations may include thermal expansion, structural support, corrosion protection, insulation clearance and access for maintenance. Buyers should confirm whether the application requires flow regulation, shut-off or low-leakage isolation, as damper designs differ in their sealing capabilities. Selecting the appropriate fabricated construction and actuation system helps support reliable airflow management, durable operation and consistent performance under the intended working conditions.
