Carrier 331709-755 R410A Thermal Expansion Valve (TXV) Kit 3-Ton

The Carrier 331709-755 is a replacement kit that includes a 3-ton thermal expansion valve (TXV) for R410A refrigerant. The TXV is an essential part of your HVAC system because it controls the amount of refrigerant that passes through the system by sensing the temperature of the evaporator coil constructed of bi-metal, the TXV changes the flow of refrigerant depending on the temperature of the evaporator to avoid flooding and to achieve the correct superheat. This kit is suitable for fixing or swapping a defective TXV on suitable Carrier air conditioning systems, which are normally installed in 3-ton capacity.
