Amana-Goodman 0151M00066 Thermal Expansion Valve R-410A

The Amana-Goodman 0151M00066 Thermal Expansion Valve is an essential component of air conditioning and refrigeration systems widely to control the amount of refrigerant allowed into the evaporator. It works based on the monitoring the temperature and pressure inside the evaporator, and adjusting the refrigerant circuits the to provide the performance. When the evaporator gets cooler the refrigerant in the bulb and so the valve opens slightly to allow more fluids to move through. On the other hand as the evaporator gets warm the bulb gets large reducing flow of refrigerant. This control makes the evaporator to work at the right temperature that can allow for maximum cooling capacity before a back pressure that leads to refrigerant flooding to the compressor.
