Nordyne 664344R 3-Ton Check Thermal Expansion Valve R-410A

The Nordyne 664344R 3-Ton Check Thermal Expansion Valve is a must have spare part for air conditioning and refrigeration systems which operate using R-410A refrigerant. Its main function is to control the flow of the refrigerant and thus ensure that cooling works at its optimum levels. The way it works involves sensing temperature changes in an evaporator coil and adjusting the passage of refrigerants accordingly. This prevents the coils from freezing while allowing sufficient heat transfer. In addition, 664344R fits into any cooling device like air conditioning machines, fan heaters or even heat pumps. Benefits include improved energy efficiency, greater cooling capacity and extended life of the equipment.
