Nordyne 669682R 3-Ton Thermal Expansion Valve R-410A TR6

The Nordyne 669682R 3-Ton Thermal Expansion Valve R-410A TR6 is a must-have for every air conditioning and heating system to manage the coolant going into the evaporator coil thus yielding either maximum cooling or heating. In addition, it adjusts the refrigerant flow depending on the surrounding temperatures about that of the evaporator coil. This prevents under or overcharging which may lead to freeze-up or compressor overheating thus contributing towards system efficiency. As such this valve also ensures the correct refrigerant level hence better efficiency of the system preventing dry-out or excessive evaporator coil temperature. R-410A is its compatible type and is majorly used in present-day HVAC systems.
