Dampers & fabricated valves
Isolation and flow-control equipment for flue-gas paths, ducts and process lines — built for high temperature, dust loading and continuous plant duty.
Control the gas path with confidence
Dampers and fabricated valves protect people and equipment when you isolate boilers, WHRB trains, fans and process ducts. GrandeH fabricates heavy-duty assemblies sized to duct dimensions, temperature, leakage class and actuator preference — for OEMs and end users across steel, sugar, power and process industries.
Product range
- Guillotine / slide-gate dampers for tight isolation
- Louver and multi-louver dampers for modulation
- Butterfly dampers for round and rectangular ducts
- Fabricated process valves and custom isolation assemblies
- Diverter and blanking arrangements for maintenance shut-offs
Typical applications
- Boiler and WHRB flue-gas duct isolation
- Forced-draft / induced-draft fan isolation and bypass
- Hot-air and process-gas ducting
- Cement, steel, power and distillery exhaust systems
Design focus
- Temperature- and corrosion-appropriate materials
- Sealing options matched to leakage and duty
- Manual, electric or pneumatic actuation interfaces
- Integration with existing duct flanges and plant layouts
Share duct size, design temperature / pressure, leakage requirement and actuator preference — we will propose a practical damper or fabricated valve package.
