Lennox 10W77 R-22 Expansion Valve

Lennox 10W77 Expansion Valve is an essential control element manufactured from durable brass for the older models of the Lennox HVAC systems, particularly air conditioners using R-22 refrigerant. This valve is crucial in providing efficiency in the system and cooling. The 10W77 checks the temperature of the evaporator coil. This information is used to control the amount of refrigerant that enters the coil. This ensures that the coil gets the right amount of refrigerant that it has to take to cool as much as possible output. Working, through the adjustment of the flow of the refrigerant, of optimizing the temperature inside the evaporator coil so that does not freeze while ensuring optimal cooling at the same time.
