Lennox 25W26 Thermal Expansion Valve(TXV) 3/8X1/2 ODF R22 4-Ton 30" Cap

The Lennox 25W26 is a Thermal Expansion Valve (TXV) used in HVAC systems, normally constructed of brass. It has the essential function of controlling the flow and pressure of the refrigerant in the closed loop. Through the detection of temperature in the evaporator coil, the TXV regulates the amount of refrigerant that gets into the coil. This helps to achieve the highest cooling levels and to avoid an icing up of the evaporator coil. In other words, it maintains exact working as an automatic valve that regulates refrigerant based on the temperature to supply consistent chilling performance in your Air conditioning system.
