Description
The Amana-Goodman 0151R00195S Thermal Expansion Valve (TXV) R-410A is a refrigerant metering valve that controls liquid flow into the evaporator coil according to cooling demand in air conditioning and heat pump equipment. It is used in split systems and packaged units where stable regulation is required for proper heat transfer. It works through a sensing bulb and diaphragm that react to fluctuations and pressure changes, adjusting opening position to maintain correct superheat and prevent liquid return to the compressor. Placed within HVAC systems, it connects between the liquid line and vaporizer section to regulate chilled air.
