What is a TXV valve?
TXV valves are components of a refrigeration device comprised of a valve and a sensor. These parts work in unison to feed the rest of the system the appropriate amounts of refrigerant. The sensor gets a read on the pressure and temperature of the refrigerant within the system and then tells the valve how much of that refrigerant should pass through.
