Bard K401-81 - Motor actuator (0/2-10 VDC)

The Bard K401-81 motor actuator is an OEM modulating control component used to position an HVAC damper or valve in response to a 0 to 10 VDC or 2 to 10 VDC control signal, helping Bard wall-mount and packaged systems maintain accurate ventilation and airflow control. This actuator is designed to integrate with the unit’s factory controls for consistent, repeatable movement, which is critical when troubleshooting economizer or ventilation performance issues. For best results, verify the required control signal range and mounting style against the unit model and wiring diagram before ordering to ensure proper fit and operation.
