Nordyne 669772 Thermal Expansion Valve R-410A

The Nordyne 669772 Thermal Expansion Valve is an essential part of HVAC systems which are utilizing R-410A refrigerant. The unit regulates the quantity of refrigerant that enters the evaporator, enabling it to achieve optimal cooling efficiency. The valve modifies the amount of coolent in order to keep adequate pressure and avoid freezing or excessive heating by means of monitoring temperature in the evaporator. Frequently this device would be employed in air conditioning units and heat pump systems for increased energy-saving and comfort levels. Accurate control translates into longer equipment lifetime as well as reduced costs on maintenance services.
