Nordyne 664275R 5-Ton Thermal Expansion Valve (TXV) R410A

The Nordyne 664275R 5-ton Thermal Expansion Valve (TXV) should only be used with R410A refrigerant. TXVs have the prime responsibility of moderating refrigerant circulation in HVAC systems so that their performance enhances. This valve incorporates a thermostatic bulb which measures the temperature of the evaporator output then regulates the refrigerant flow into the evaporator. The TXV prevents the evaporator from both overloading and underloading, thereby enhancing energy efficiency and comfort. The Nordyne 664275R is fit for most of the 5-ton HVAC units such as the air conditioner and heat pump.
