Bard part 804-0407 is a factory OEM cooling TXV with external equalizer used in Bard wall mounted air conditioners to meter refrigerant flow to the evaporator and maintain stable superheat under changing load and airflow conditions. A properly sized, correct TXV helps prevent coil floodback and hunting while supporting consistent suction pressure and reliable cooling performance. Because TXVs and equalized connections are application specific, confirm the unit model and serial number, refrigerant type, and the exact piping configuration before ordering so the valve matches the original Bard design and installs without modification.
* Orders less than $50 may incure a minimum order fee.
