Description
The Lennox 64W49 Thermal Expansion Valve (TXV) is the control element intended for the Lennox air conditioners with a 4-ton cooling capacity. This is a strong valve that is used to ensure that the system efficiency and cooling are attained. The TXV uses a long, thin capillary tube (30 Inches) to measure the temperature of the evaporator coil. On this basis, it accurately controls the amount of refrigerant that enters the coil through the 3/8-Inch diameter inlet. The outlet has a 1/2-Inch ODF connection that allows it to be fitted in compatible refrigerant lines perfectly.
