QUADRO. The right version for every application.
QUADRO is available in several versions, but the functional principle is always the same.
The butterfly valve controls the flow of air in a ventilation duct. The damper operation is controlled manually, pneumatically or electrically.
When the flap is closed, the line is sealed 100% gastight. The gasket attached to the damper disc ensures that no pressure can escape.
QUADRO with hand pump
In the version with the PERFEKT tightness test, you can check the 100 % tightness at any time by means of a hand pump with pressure gauge. Test pressure is built up via a test groove milled into the housing.
