The Bard 800-0151 Expansion Valve Assembly is an OEM refrigerant metering component used in Bard wall mounted package air conditioner systems to regulate refrigerant flow into the evaporator based on operating conditions, helping maintain proper superheat, stable cooling performance, and compressor protection. If your unit is showing symptoms like erratic suction pressure, icing, poor cooling, or flooding back after other airflow and charge issues have been ruled out, replacing the expansion valve assembly with the correct Bard part number is a practical way to restore the factory engineered refrigerant control and fitment for your specific model series.
Please call for available options or find replacement parts.
