So, here we go. A TXV valve, or a thermostatic expansion valve, is a very precise valve that regulates the rate of flow of refrigerant to the evaporator on an air conditioning system. It’s purpose is to maintain an efficient flow of refrigerant while also protecting the compressor. These features of the TXV valve are explained below. 5). If the valve head becomes colder than the bulb, malfunction of the expansion valve occurs (i.e. erratic low pressure or excessive superheat). Factory settings: The table below provides the factory setting position of superheat adjusting stem and shows the number of turns (360°) clockwise when adjusting stem fully open counterclockwise The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling and superheat inside and outside. The goal is to look for the temperature differences between the inside and outside measurements.allow the pushrods to drop out of the valve body during assembly. 4. Install new adjustable bottom cap assembly furnished with kit. 5. With the system operating, check the superheat, (see enclosed Temperature-Pressure card), and adjust the valve if necessary. Install and tighten seal cap, this cap is the primary seal. Thermostatic Expansion ValveBased on which one it is, the AC expansion valve will either restrict the flow of refrigerant to the evaporator or increase the flow. This ensures the air conditioning system keeps running smoothly without any setbacks. 5 Bad Symptoms. If the AC expansion valve ever malfunctions, certain symptoms will present themselves.

With both the temperature and pressure readings in hand, refer to a superheat chart to find out the existing superheat level. This step is essential in understanding how much adjustment is needed.
