Perfect tightness ensured by the silicone membrane, is the main advantage of this non-return valve, the Dalap GBV for square ducts. In the resting state, stable closing of the membrane is ensured by a magnet. This eliminates the possibility of unintended momentary opening of the flap itself (e.g. during gusts of wind). The intensity of the magnet can be adjusted and easily set by tightening or loosening the screw as required.
