Lennox 25W23 Thermal Expansion Valve(TXV)

The Lennox 25W23 is a Thermal Expansion Valve that is used in HVAC systems. It controls the circulation of refrigerant which is a major factor for right cycling and maximum performance. The TXV works by feeling the evaporator temperature, and in turn, it controls the refrigerant circulation to avoid overfeeding the evaporator coil. The function of the cycle pump to cause the expansion valve to regulate refrigerant flow helps to keep cooling performance steady and prevent the compressor from suffering damage due to low levels of refrigerant. The characteristics as size 1/2”, TXVs do not control natural gas and work on much lesser voltage than 230V.
