The expansion valve, also known as a metering device, plays a vital role in the air conditioning system. It controls the amount of refrigerant that enters the evaporator, allowing it to absorb heat from the cabin and provide cooling. 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, system over-pressurization, or ice formation. NISSENS is a reputable brand known for its quality automotive components.
