Depending on the characteristics of a particular Automotive Engine Expansion Valves, this thermostatic valve can have a different design. However, at its core, it is a special thermal tube that is located in the evaporator and connects to the diaphragm, and through it to the valve. It is installed in the section of the pipeline through which the refrigerant is directed to the evaporator.

If the temperature at the outlet of the device increases, the valve opens, letting in more special liquid inside. With a decrease in the temperature regime, it closes, reducing this flow.

In the event of a malfunction of the expansion valve, the spontaneous shutdown of the entire system is possible, interruptions in air cooling, freezing of the evaporator pipes occurs. The reason why the thermostatic expansion valve fails is an incorrect adjustment, dirt or moisture inside the system, as well as mechanical damage to this unit. In this case, cleaning, restoration or replacement of the valve is required.

The most common problem is a stuck needle that opens and closes the refrigerant flow. To fix this problem, certain repair actions are carried out, requiring the dismantling of the valve, as well as the removal and subsequent filling of Freon or other gaseous substance.
