Overflow valve ÜV 200 consisting of special cement pipe with inserted fire shut-off damper BAK 200 and cold smoke shut-off damper KAK 200. Used in buildings with smoke protection pressure systems, as overflow valve in walls between stairwell and airlock/anteroom/necessary corridor. This provides an air connection between these two rooms to achieve pressure equalisation. Flow only in one direction due to the KAK shut-off damper. Tight against smoke transmission in the opposite direction. Can be extended with a cover sleeve and a viewing panel as required accessories.
