Description
The Trane VAL09963 Expansion Valve Assembly is a thermal component used in R410A systems to regulate refrigerant flow into the evaporator coil. It regulates the pressure & temperature of refrigerant entering the indoor coil, ensuring stable heat exchange during cooling or heating operations. This component is typically placed at the inlet of the evaporator section in split and packaged HVAC systems. It is used in air conditioning & heat pump systems to maintain correct superheat levels and protect the compressor from liquid refrigerant return supporting consistent system performance under varying load conditions.
