Description
The Trane VAL9573 is a Thermal Expansion Valve (TXV) used exclusively in Trane HVAC equipment and is responsible for controlling the refrigerant. This valve is fundamentally a pressure-controlled switch. The Trane operates based on the temperature of the refrigerant leaving the evaporator coil and responding to it. During the cold season, the valve opens a little to allow more refrigerant to flow and to take heat from your home. On the other hand, if the temperature rises, the valve narrows cutting down refrigerant circulation to avoid freezing. This precise control of refrigerant is essentialfor the efficiency and the temperature setting of your Trane HVAC system.
