High Temperature Damper Butterfly Valve

ALIS Valves offers High Temperature Damper Butterfly Valves for industrial applications requiring reliable airflow regulation and gas control under elevated temperature conditions. These valves feature a rotating butterfly disc that adjusts the flow passage to regulate or restrict the movement of hot air and compatible process gases. Depending on the application, the valve can incorporate heat-resistant body and disc materials, suitable shaft arrangements and high-temperature sealing components designed for the specified thermal conditions. The valve construction can be adapted to suit different duct sizes, installation layouts and process requirements. Manual, pneumatic or electric actuation options may be available to support local operation, remote control or integration with industrial automation systems. Proper material selection and thermal design are important for maintaining mechanical stability and dependable operation during repeated temperature changes.

High Temperature Damper Butterfly Valves are used in power generation plants, steel manufacturing facilities, cement plants, industrial furnaces, incineration systems, hot gas ducts and exhaust handling installations. They are suitable for regulating airflow and compatible gases where the valve’s materials, operating temperature and pressure ratings meet the process requirements. Important selection factors include maximum operating temperature, differential pressure, duct dimensions, gas composition, flow capacity, body and disc materials, shaft and bearing design, sealing performance and actuator torque. Thermal expansion, heat transfer to the actuator, insulation clearance and access for maintenance should also be evaluated during system design. Buyers should confirm whether the application requires airflow regulation, isolation or low-leakage shut-off, as damper valves vary in their sealing capabilities. Selecting the appropriate valve construction and actuation system helps support reliable flow control, resistance to thermal stress and consistent performance under specified high-temperature operating conditions.
