A constant air volume valve is a mechanical self operated device suitable for ventilation and air conditioning systems that require a constant air volume. The air volume control of the constant air volume valve does not require external power. It relies on the airflow force inside the air duct to position the control valve, thereby maintaining the airflow at a predetermined flow rate throughout the entire pressure difference range.

Classification of constant air volume valves

One type is to use silicone airbags in the balancer to sense the airflow flowing through the air duct, and automatically contract and expand according to different static pressures to achieve a constant air volume. When the air static pressure at the inlet and outlet is low, the airbag is in a contracted state. When the static pressure at the inlet and outlet increases, the airbag begins to expand, thereby reducing the gap around the airbag. Maintain a constant flow rate within a certain range of wind pressure.

Another type is a mechanical self operated device that relies on the air pressure inside the duct to position the control valve, thereby maintaining the airflow at a predetermined flow rate within a certain pressure difference range. It does not require external power and can be equipped with an electric actuator to change the flow setting through remote control signals.
