- Product Description
- Technical parameters
-
Technical Characteristics:
A constant air volume valve is a mechanical, self-acting device suitable for ventilation and air conditioning systems requiring a constant air volume. It doesn't require external power for air volume control; instead, it relies on airflow within the duct to position the valve blades, maintaining airflow at a preset rate across the entire pressure differential range.
Product Features:
Airflow Adjustment: Automatic mechanical mechanism, requiring no external power.
Operating Temperature: 10-50℃
Pressure Range: 50-950Pa
The air bag also acts as an oscillation damper.
External pointer displays airflow scale, with a scale error of ±8%.
Valve body thickness: 400mm
The air valve blade control mechanism is maintenance-free
