Circular volume damper

Round section air valves are used to regulate the air volume in circular ventilation ducts. Versions with manual control and electric actuators are available. Manual valves are adjusted manually to the required air volume and locked in place using a locking mechanism on the lever. Versions with actuators can be equipped with 24V or 230V servomotors upon request. The body, valve, and valve lever are made of galvanized metal.
