Nordyne 920672A 4-Ton Thermal Expansion Valve (TXV) Kit R410A

The Nordyne 920672A 4-Ton Thermal Expansion Valve kit weighing 4 tons is a necessary device for air conditioning and heating systems. This is how the valve controls the refrigerant of flow into the evaporator coil, hence achieving maximum cooling/heating performance. To measure the temperature of the evaporator coil, the TXV employs a sensor bulb. It adjusts refrigerant flow in order to maintain the desired superheat depending on the above value. This exact control avoids overcooling or under-cooling, thus ensuring efficiency and comfort altogether. The TXV kit specifically designed for 4-ton A/C and heating units using R410A refrigerants is highly utilized in various residences and businesses such as: private houses, apartments, little companies etc.
