Product features
- Customer-specific round, rectangular or special construction → Fits the actual duct geometry and installation constraints.
- DN50–DN2000 size range → Covers both compact process lines and very large gas ducts.
- Operating pressure up to 500 mbar → Supports demanding air and flue-gas isolation duties.
- Temperature up to +650 °C → Suitable for high-temperature exhaust and hot-gas service.
- Higher-temperature versions on request → Extends application coverage beyond the standard range.
- Electric or pneumatic actuation → Enables integration into automated plant operation.
- Optional position switches and sensors → Provides reliable open/closed or intermediate position feedback.
- Broad material selection → Helps match temperature, corrosion and gas-composition requirements.
- Application-specific engineering → Reduces the risk of unsuitable leakage, torque or thermal behaviour.
- AxFlow selection and service support → Simplifies specification, spare-parts planning and lifecycle maintenance.
Noval Dampers are intended for air and flue-gas handling duties where standard liquid-service valves are not the right solution. Typical applications include fume exhaust, flue-gas ducts, hot-gas generators, gas purification and other process-gas systems that require a large flow area, defined shut-off behaviour and construction adapted to the duct arrangement.
The dampers are manufactured to customer-specific technical requirements and can be supplied in round, rectangular or special constructions. AxFlow lists nominal sizes from DN50 to DN2000, operating pressure up to 500 mbar and temperature capability up to +650 °C, with higher-temperature versions available on request. Electric or pneumatic actuators and external position switches or sensors can be added when remote operation and position feedback are required.
A broad choice of construction materials allows the damper to be matched to gas composition, temperature and corrosion conditions. Selection should also consider differential pressure, required leakage class, duct geometry, actuation time and the thermal expansion of the surrounding installation.
For lifecycle cost, correct sizing and materials are more important than simply selecting the largest damper. A well-matched construction can reduce operating problems caused by distortion, leakage or unsuitable actuation, while service access and replaceable wear components support planned maintenance. AxFlow can help specify the correct Noval damper and support spare parts and service requirements.
