Description
The Amana-Goodman 0151R00231S is a Thermal Expansion Valve (TXV) for use with R‑410A refrigerant in air‑conditioning and heat pump systems. It meters liquid refrigerant into the evaporator coil while responding to temperature and pressure at the coil outlet, maintaining a stable superheat level across varying cooling loads. Mounted between the condenser and evaporator circuits, the valve connects to a sensing bulb and adjusts its opening to regulate refrigerant feed, supporting maximum heat-transfer efficiency and protecting the compressor from return. Within the system, it operates as the primary metering part, enabling coordinated operation between the outdoor units.
