The AXV is a constant pressure regulator. It is designed and constructed to maintain a constant evaporating pressure. The flow of the refrigerant into the evaporator is based on the pressure of the refrigerant in the evaporator.

What is the function of the Txv?

How thermostatic expansion valves work. A thermostatic expansion valve (TXV) (see Figure 1) is a refrigeration and air conditioning throttling device that controls the amount of refrigerant liquid injected into a system’s evaporator—based on the evaporator outlet temperature and pressure—called the superheat.
