Functional description
Supply air valves direct the air from air conditioning systems into the room. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.
Type Z-LVS disc valves have a valve disc that can be turned. Horizontal air discharge is radial.
This valve disc facilitates volume flow rate balancing for commissioning.
Nominal sizes | 100, 125, 160, 200 mm |
Minimum volume flow rate | 10 – 30 l/s or 36 – 108 m³/h |
Maximum volume flow rate | 25 – 90 l/s or 90 – 324 m³/h |
Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

Circular disc valves as supply air devices, preferably for small rooms. For installation into walls and suspended ceilings.
Ready-to-install component which consists of a valve casing with cross bar, a valve disc with threaded spindle, and an installation subframe.
The valve disc can be turned for volume flow rate balancing. The valve setting can be fixed with a lock nut.
Spigot suitable for ducts to EN 1506 or EN 13180.
Sound power level of the air-regenerated noise measured according to EN ISO 5135.
