Amana-Goodman 0151R00173 Thermal Expansion Valve R-410A

The Amana-Goodman 0151R00173 TXV is an essential part of light commercial air conditioning, residential and and heat pump HVAC system using R-410A refrigerant. This part regulates the vapor of the refrigerant flowing to the evaporator coil according to the cooling load of the system. When the load is on, the TXV opens wider to allow more refrigerant to flow to cool the system adequately. On the other hand, it regulates flow during lighter loads so that it does not over-cool and thus enhances efficiency.
