product description
Constant air volume valve is a mechanical self-supporting device, suitable for ventilation and air conditioning systems that require constant air volume. Constant air volume valve Air volume control does not require external power. It relies on the air flow force in the duct to position the control valve, so that the air flow is maintained at a preset flow rate within the entire pressure difference range.
Features of constant air volume
Constant air volume valve is an automatic mechanical mechanism, no external power is needed, and an electric actuator can be added to change the flow setting through a remote control signal. Constant air volume valve can be used in both air supply and exhaust systems. The working temperature is generally 10 ~ 50 ℃, and the pressure difference range is 50 ~ 1000Pa. That is, at least 50Pa pressure difference should be applied after the valve before the valve. This point should be noted, because the wind pressure value of the fresh air unit of the fresh air system is generally not large. The fixed air volume valve is not restricted by position when installed, but the valve shaft should be level. Generally, a linear inlet duct with a distance of 1.5 times the long side of the valve and a linear outlet duct with a distance of 0.5 times are generally required.
Constant air volume valve has high control accuracy, external pointer shows flow scale, adjustment accuracy is about ± 4%, no need for maintenance of the current limiting mechanism. In order to match the system, the constant air volume valve can be selected from rectangular, circular, heat preservation and noise reduction types. Just as the balancing valve is more and more used by the majority of designers in air-conditioning water systems, the fixed air volume valve will be widely used in the supply and exhaust systems due to its precise and adjustable and automatic balancing characteristics.
