Working principle

The flue gas damper with single disc is operated by manual clutch or single pneumatic actuator (could be FC or FO position when power failure).

To close the damper, the damper disc touch the sealing rings (two malposed half rings) to get the plane sealing effect; the damper shaft and half rings are unique designed for surface sealing.
