Bard 5651-165 - Pressure Relief Valve

The Bard 5651-165 Pressure Relief Valve is an OEM safety valve used in Bard HVAC equipment to protect the sealed refrigeration system from abnormal pressure conditions by venting at its calibrated set point. When a system is exposed to an overpressure event, a properly functioning relief valve helps reduce the risk of component damage and refrigerant loss that can occur when pressures climb beyond safe limits. This part is a direct-fit Bard replacement intended to restore factory safety performance, so confirm the exact 5651-165 match to your unit model and service documentation before ordering, and replace any related seals or connections as required by your installation procedure.
