Bard 5651-198 - Expansion Valve 3/8 x 3/8

The Bard 5651-198 expansion valve is an OEM refrigerant metering component used in Bard wall-mount air conditioners to regulate the flow of refrigerant into the evaporator coil for stable superheat and consistent cooling performance. With 3/8 inch by 3/8 inch connections, this valve helps the system respond properly to changing load conditions, supporting efficient operation and protecting the compressor from improper refrigerant feed. Because expansion valves are application-specific, confirm compatibility by matching the part number 5651-198 to your Bard model and serial information before ordering, and have installation performed by a qualified HVAC technician who can properly evacuate and recharge the system.
