Bard 5651-167 - 450 PSIG Pressure Relief Valve

Bard part 5651-167 is an OEM pressure relief valve with a 450 psig setting used to protect the sealed refrigerant circuit in Bard wall mount HVAC equipment by venting safely if system pressure rises beyond its design limit. In the field, a properly matched relief valve is a critical safety component that helps prevent damage to high side components during abnormal conditions such as overheating, severe airflow restriction, or overcharge. Replace this valve only with the correct Bard-specified part number to maintain proper pressure protection and system reliability, and confirm the exact model and serial range for compatibility before ordering.
