Damper Double Flanged Butterfly Valve

ALIS Valves offers Damper Double Flanged Butterfly Valves designed for flow regulation and isolation in industrial air, gas and ventilation systems. These valves feature a rotating disc or damper blade mounted on a shaft that turns to regulate or shut off the flow passage. The double-flanged body provides bolted connections at both ends, allowing secure installation between compatible pipeline or ducting flanges. Depending on the design, these valves can be used for controlling airflow, exhaust gases and other compatible gaseous media in industrial processes. Body materials, disc construction, shaft arrangements, sealing options and operating mechanisms can be selected according to the required temperature, pressure, flow characteristics and installation conditions. Manual, gear-operated, pneumatic or electric actuation options may be available depending on the application and control requirements.

Damper Double Flanged Butterfly Valves are used in industrial ventilation, HVAC systems, power plants, dust collection equipment, exhaust lines, furnaces and other applications requiring controlled movement of air or gases. Their suitability depends on the operating temperature, pressure differential, gas composition, flow rate and required leakage performance. Important selection factors include valve size, flange standard, body and disc materials, shaft design, sealing arrangement and actuator torque. Buyers should also determine whether the valve is intended for simple isolation, airflow regulation or high-temperature gas service, as these duties may require different construction and sealing arrangements. For automated installations, actuator sizing and compatibility with the control system should be verified. Selecting the appropriate damper double flanged butterfly valve helps provide reliable flow regulation, secure installation and dependable operation in compatible industrial air and gas handling systems.
