Definition of expansion valve. : a valve through which liquid or gas under pressure is allowed to expand to a lower pressure and greater volume.
The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm.This may be verified by feeling the liquid line at its connection to the expansion valve.The liquid refrigerant leaving the expansion valve is quite cold. The orifice within the valve does not remove heat, but only reduces presÂ­sure.Heat molecules contained in the liquid refrigerant are thus allowed to spread as the refrigerant moves out of the orifice.he liquid refrigerant leaving the expansion valve is quite cold.
