Description
The Trane VAL 4471 Thermal Expansion Valve is produced for the HVAC systems that were manufactured before 2010 that used R 22 refrigerant making it obsolete because of environmental impact. This valve with a length of 5.5 inches is vital for raising the performance of the system and preserving the compressor. This is a heavy brass automatic flow control for R-22 refrigerant that can handle up to 250 degrees F. This accurately calculates the quantity of the refrigerant that enters the evaporator coil from fluctuation in temperature. It uses sweat connections for installation and has a maximum working pressure of 500 psi.
