Amana-Goodman 0151R00178S 5-Ton Thermal Expansion Valve R410A

The Amana-Goodman 0151R00178S 5-ton thermal expansion valve is an essential part to work with R410A refrigerant in home and light-commercial air conditioning applications. TXVs are indispensable in air conditioning and refrigeration systems, it has an function of regulating refrigerator into the evaporator. This particular model a sensing bulb to measure the temperature of the superheated refrigerant which is leaving the evaporator. The TXV based on this temperature reading controls the amount of refrigerant flow to the desired level. If the refrigerant is very low, the TXV is pushed open and hence allows more flow of the refrigerant. if the refrigerant is too hot, the TXV throttles the flow so as not to allow an excessive temperature.
