8620-111 OBSOLETE
- Direct Vent Check Valve
Bard part number 8620-111 is an OEM direct vent check valve used on select Bard wall mounted HVAC equipment to help maintain proper one way airflow through the unit’s venting path. A functioning check valve is important for stable ventilation performance and to reduce unwanted backdrafting, especially on systems equipped with factory vent options. This replacement is intended to restore correct vent operation and fit, but because Bard lists check valves across multiple model families, confirm compatibility by matching the part number to your unit’s specific parts list or service manual before ordering.
