About Product

A Variable Air Volume (VAV) system is a type of HVAC (Heating, Ventilation, and Air Conditioning) system that adjusts the airflow to different zones in a building based on the temperature requirements of each zone. The term "zonal valve box" could be a component within such a system.

In a VAV system, each zone typically has its own VAV box, which contains a damper and sometimes a heating or cooling coil. The damper regulates the airflow into the zone, and the system modulates the temperature to meet the setpoint for that zone. The term "zonal valve box" might refer to a box housing valves or dampers that control the airflow in a specific zone.
