Mechanical Constant Air Volume Valve

Product Specifications:

1. A constant air volume valve is a mechanical, self-operated device designed for use in ventilation and air conditioning systems that require a constant airflow.

2. The constant air volume valve does not require an external power source for airflow control; instead, it uses the force of the airflow within the duct to position the valve blades, thereby maintaining the airflow at a preset rate across the entire pressure differential range.

Product Features:

1. Airflow adjustment: Automatic mechanical mechanism requiring no external power source.

2. Operating temperature: 10–50°C.

3. Pressure range: 50–950 Pa.

4. The air bladder also serves as a vibration damper. An external pointer displays the flow rate scale, with a measurement error of ±8%. The air valve blade control mechanism is maintenance-free.
