The Trane VAL8989 is a Thermal Expansion Valve specifically for applying R410A refrigerant to Trane HVAC systems. The small capacity of this valve can be essentialfor controlling the refrigerant flow throughout the system enough to cool properly. The TXV is an automatic valve that controls the volume of refrigerant getting into the evaporator coil. The TXV senses temperature and pressure in the coil and flows STW as required to achieve maximum performance. This controlled flow uses refrigerant efficiently and maintains consistent temperatures you seek in your home.
