The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
The expansion valve is usually in the evaporator and simply opens or closes to allow the appropriate flow of refrigerant into the coil. The theory is that the expansion valve makes your AC run more efficiently.
