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.
