OBD valve

OBD valve (Opposed Blade Damper) is an air flow adjustment valve that uses symmetrically moving valve blades (opposed blades), helping to distribute and control air flow more evenly and accurately than conventional valves. The valve can be controlled by hand or motor, allowing integration into the automatic control system (BMS/SCADA), ensuring optimal operating performance for the HVAC system.

OBD valve is used in ventilation and air conditioning systems in buildings and shopping centers commercial, factory, clean room and technical works, where precise and stable air flow control is required.
