Self-Powered Airflow Regulator for Perfect Balance
The constant air volume valve, also called a CAV valve, is a mechanical device that requires no external power. It uses an internal spring and balancing mechanism to automatically adjust its opening. This keeps the airflow through the valve steady at the preset volume, even when duct pressure changes. That is why the product is an excellent solution for precise airflow control. Once set, the product ensures that every outlet receives exactly the air it needs.
Solves Balancing Problems and Saves Time
The product solves several common HVAC challenges. First, it guarantees the designed airflow to each room, which is vital for proper ventilation, temperature control, and pressure balance. Second, it automatically compensates for pressure fluctuations when other dampers move or filters become clogged. This prevents the "airflow competition" effect. Third, it significantly reduces commissioning time. Instead of manual trial-and-error adjustments, you simply set the constant air volume valve, and it balances itself. This results in lower labor costs and long-term accuracy. Fourth, it improves system stability and saves energy by preventing oversupply to certain areas.
Where to Use This product
The product is ideal for critical environments where airflow must remain constant. Common applications include hospital operating rooms, ICUs, negative pressure isolation rooms, and biological laboratories. It is also well suited for chemical laboratories and animal facilities that require precise air change rates. In industrial cleanrooms, the product maintains correct supply airflow and positive pressure. Below are the key specifications:
