What Does This Ac Expansion Valve Do?

The thermostatic expansion valve (TXV) or orifice tube meters the flow of liquid refrigerant from the high-pressure side of the AC system into the evaporator, allowing it to expand and drop in pressure. This controlled pressure drop enables the refrigerant to absorb heat efficiently as it evaporates inside the cab evaporator.

Possible Ac Expansion Valve Problem Symptoms

If your machine is showing any of the following, a faulty ac expansion valve may be the cause:

  • AC system not cooling effectively despite refrigerant charge and compressor operation being confirmed correct
  • Ice forming on the evaporator or expansion valve body due to the valve opening too far
  • Warm air on one side of the evaporator and cold on the other, caused by an uneven flow restriction
  • High suction pressure and low superheat at the evaporator outlet, indicating an over-open valve
