The expansion/throttle valve represents the interface between the high-pressure and low-pressure sections in the refrigerant circuit and is installed upstream from the evaporator. The liquid refrigerant is injected into the evaporator via the expansion/throttle valve. The refrigerant expands and evaporates, releasing evaporation cooling. The refrigerant flow through the expansion/throttle valve is regulated to achieve optimum cooling output in the evaporator. Humidity and soiling in the air-conditioning system can severely impact the functional capability of expansion/throttle valves and lead to malfunctions.
In terms of technology, air-conditioning systems are becoming more and more complex. As a result, all Behr Hella Service components and their function have to be perfectly matched to the driver's demand for comfort to ensure properly functioning vehicle air-conditioning. The comprehensive system range offers your customers outstanding service.
