Bard part number 1806-0878 is an OEM expansion valve to quick connect used in Bard wall-mounted air conditioners and heat pumps to meter refrigerant into the evaporator and maintain proper superheat under changing loads. Replacing a restricted, leaking, or unstable expansion valve helps restore normal suction pressure control, prevents coil floodback, and improves cooling performance. Because this component interfaces directly with the refrigerant circuit, confirm the unit model and refrigerant type in the Bard service literature before ordering, and have installation performed by a qualified technician who can properly evacuate, recharge, and check system operation after replacement.
* Orders less than $50 may incure a minimum order fee.
