Description
The Amana-Goodman 0151R00193S Thermal Expansion Valve (TXV) R-410A is a refrigerant control valve that regulates liquid flow into the evaporator coil according to cooling demand in air conditioning and heat pump systems. It is mounted in split systems and packaged units where accurate metering is required for stable operation. It works through a sensing bulb and internal diaphragm that respond to temperature and pressure changes, adjusting flow to maintain correct superheat and prevent liquid return to the compressor. Located within HVAC systems, it connects between the liquid line and evaporator assembly to manage distribution and support heat exchange efficiency.
