Diverter Dampers

General Information

Effox-Flextor has extensive experience in the design and supply of toggle-type and pivot-type diverter dampers for HRSG, Waste Heat recovery, natural gas turbine, and other systems that require diversion of the gas stream. We have designed and installed diverter dampers in systems ranging from small turbine units to the largest turbines in the world such as the GE Frame 7.

Drive Options

Effox-Flextor has a wide range of drive options from simple shaft mounted pneumatic actuation, to heavy-duty electric and hydraulic actuation with fail safe configurations.

  • Electric drives
  • Hydraulic and pneumatic drives

Seat Configurations

Depending on the application, seat configuration can play a major role in the operation of any damper. Effox-Flextor offers a full range of proven seat configurations including;

  • Metal to metal bar seat
  • Blade lip leaf seal
  • High-Flex metal seat for tight shut-off - high temp
  • Composite seals for tight shut-off - low temp

Stuffing Box / Bearings

Bearings make the difference. Our dampers are designed with bearings that meet the challenges of the operation, yielding high levels of efficiency and reliability.

  • Machined coupling gland
  • Compression gland
  • Roller bearing - maintenance free

Blade Designs

Effox-Flextor dampers are available with simple blades, structural blades, thermally compensating blades, and profiled blades. For applications where heat retention is necessary, blades can be insulated.
