905-0539 OBSOLETE
- Expansion Valve Assembly
The Bard 905-0539 is an OEM expansion valve assembly used in Bard wall mounted air conditioner and heat pump systems to meter refrigerant into the evaporator coil and maintain proper superheat under changing load conditions. A properly operating expansion valve helps prevent coil flooding or starvation, supporting stable capacity, humidity control, and compressor protection. Because this is a refrigerant circuit component, correct identification by unit model and serial number is important, and installation should be performed by a qualified technician following Bard service procedures for evacuation, charging, and leak checking.
