The Young Regulator Model CVDxx is a round damper designed to deliver a pressure-independent, calibrated maximum airflow. The airflow setting is adjustable over a wide range of flows. Flow can be adjusted manually but not by end users. The asymmetrical blade positions itself to restrict free area as the flow increases thus providing pressure-independent control without the need for electrical connections.Â The unit is made of heavy-gauge steel. It is available in stainless steel. (Contact the factory for more details)
There are two ways to configure the CVDRs.Â By themselves they provide flow up to a preset airflow.Â Add a motor and now they can maintain one airflow when the motor is unenergized and a different higher set-point when the motor is energized.(Application Example: day/night â€” occupied/unoccupied
