The expansion valve, also known as a metering device, plays a vital role in the refrigeration cycle of your car's air conditioning. It controls the flow of refrigerant into the evaporator, allowing it to expand and absorb heat from the cabin. Proper functioning of the expansion valve is essential for maintaining the desired cabin temperature and preventing damage to other AC components. A faulty valve can lead to insufficient cooling, excessive system pressure, or even compressor failure.
