Smart Air Control Valve
Product Description
The Distech Controls' Smart Air Control Valve is a highly accurate, fully dynamic, pre-assembled air control valve solution. It has a superior turndown
ratio and measures airflows as low as a few CFM. With this low airflow design, the same Smart Air Control Valve model can be used to control the
airflow required for various applications and at a much wider range of space occupancy levels. It offers a breakthrough air flow measurement technology
that results in energy efficiency and low EUI (Energy Use Intensity), superior IEQ (Indoor Environmental Quality) and IAQ (Indoor Air Quality).
The Smart Air Control Valve is designed for low-pressure and low-velocity operation under 2"WC of inlet static pressure. Appropriate
measures should be taken to reduce the operating static pressure when this is above 2"WC.
