Description

The IGI Round Volume Control Damper (RVCD) delivers a simple, reliable, and costeffective solution for manual or motorized airflow control in standard HVAC round ductwork. The RVCD features a single butterfly blade inside a cylindrical casing, providing smooth proportional flow regulation and positive shutoff. The IGI RVCD can be supplied with a PVC or galvanized steel hand quadrant for manual balancing, or with 24V/230V motorized ON/OFF actuators for BMS-integrated zone control. Galvanized steel is the standard construction; stainless steel (SS304/SS316) and aluminium are available for corrosive or food-industry environments.
