Round Duct Valves RDR

RDR air dampers are designed to close air ducts and/or regulate air flow. The body and damper are made of galvanized steel sheet. The damper of the RDR-…M dampers is equipped with a rubber seal, ensuring tight closure of the channel. The damper body is equipped with rubber seals for connecting air ducts or other elements of the ventilation system.

The air dampers are controlled manually using a handle that allows you to fix the damper in the desired position or using an electric drive.
The dampers remain operational and can be used regardless of their spatial orientation.
