KNT air supply valves can be installed in the ceiling, on the wall or directly in the mouth of a ventilation duct using a dedicated RML mounting frame. They allow smooth adjustment of the air exhaust flow rate by rotating the disk closure in the centre.
KNT air supply valves can be installed in the ceiling, on the wall or directly in the mouth of a ventilation duct using a dedicated RML mounting frame. They allow smooth adjustment of the air exhaust flow rate by rotating the disk closure in the centre.
The air flow rate depends on the opening ratio, i.e. the distance between the disk closure distance and the round
bezel, and it is set with a locknut. The carefully designed geometry of the valve guarantees low noise level as well as quick and easy installation.
