Air Conditioning Expansion Valve
Mitsubishi FUSO®

The Air Conditioning Expansion Valve, also known as the AC expansion valve or thermal expansion valve, is a crucial component of a truck's air conditioning system. It is responsible for regulating the flow of refrigerant into the evaporator coil by controlling the pressure and temperature of the system. The ME733309 model is a specific part number for an AC expansion valve that may be used in various truck models. As refrigerant flows through the valve, it undergoes a dramatic pressure drop and becomes much colder, allowing it to absorb heat from inside the truck cab more efficiently. This process ultimately results in cooler air blowing through the vents. Proper maintenance and replacement of faulty valves can help ensure optimal performance of a truck's air conditioning system.
