Overflow valves ÜV 160 / ÜV 200
1.7 Product description
The overflow valves ÜV 160 / ÜV 200 consist of a duct sleeve made of steel sheet, in which the Helios in-duct fire
damper BAK 160 or BAK 200 and/or the Helios cold smoke shutter with magnetic closure KAK 160 or KAK 200 are
installed. Internal beading in the duct sleeve ensures the axial positioning of the mounting parts (BAK and/or KAK) and
prevents the components from slipping out during installation and inspection work. Screens and cover sleeves and/or
metal disc valves are available as accessories for both openings (see Chapter 5.2).
— In-duct fire damper BAK 160 / BAK 200
The ready-to-install in-duct fire damper BAK prevents the spread of fire and smoke. For installation in walls which serve
as fire sections with the required fire resistance class K 90-4102 or EI 90.
When an ambient temperature of +72°C is exceeded, the integrated fusible link releases the semi-circular damper
blades which close abruptly by spring force. Two safety brackets lock the shutters.
The in-duct fire damper is a construction product according to European Construction Products Regulation 325/2011
with a corresponding declaration of performance.
Details can be found in the BAK installation and operating instructions.
— Cold smoke shutter with magnetic closure KAK 160 / KAK 200
The ready-to-install cold smoke shutter with magnetic closure KAK is used to prevent cold smoke from entering other
fire sections. The cold smoke shutter with magnetic closure functions automatically and energy-independently as a
duct shutter. The double-sided plastic shutter frame (with metal insert) closes the supply air and extract air openings to
prevent the entry of cold smoke via a silicone membrane and the permanent magnets integrated in the frame.
Details can be found in the KAK installation and operating instructions.
