This diagram shows the forces of the TXV’s flexible diaphragm. Courtesy, Sporlan Division, Parker Hannifin Corp. January 26, 2021. The thermostatic expansion valve (TXV or TEV) is a metering device located between the refrigeration system’s liquid line and the evaporator. It is a rather complex valve with a remote bulb feedback …There are several metering devices in a typical system, including the thermostatic expansion valve (TEV or TXV), automatic expansion valves, electronically-governed expansion valves, balanced port TEVs, superheat and multi-circuited TEVs, and evaporators. The two basic functions of a metering device include: Feeding refrigerant to the evaporator.These features of the TXV valve are explained below. Another name for the TXV valve is the thermal expansion valve. By controlling the flow of the liquid refrigerant with the TXV valve, the evaporator on your air conditioning unit or heat pump will run more efficiently. The TXV valve also serves to protect the mechanical reliability of the unit.As a world leader in refrigerant flow controls, Sporlan Division of Parker Hannifin continues to meet the challenges of the future.

Adjusting the superheat setting may only serve to mask your problem and should not be undertaken lightly. You should really be sure of your the air volume across the evap and the load its generating. Does the unit have a sight glass, whats the liquid temp, is the TXV bulb secure and placed properly. select a Sporlan Thermostatic Expansion Valve (TEV) with correct capacity, selective charge, external or internal equalizer, etc. See Bulletins 10-9 and 10-10 for complete application information. Equally important is the proper installation, which can determine the success or failure of the entire system. n Valve LocationQ: What is the correct way to diagnose a TXV? A: First, take all of your refrigerant readings and your liquid line and suction temperature at both ends (on a split system). This means superheat, subcooling, suction saturation (evaporator coil temp), and liquid saturation (condensing temp). For a TXV to do what it is supposed to, you need a full ...For example, the same size orifice that feeds 0.96 tons of capacity for R-22 will only feed 0.63 tons for HFC-404A, or 0.56 tons for HFC-422D on a 20° evaporator. As you can see, the capacity of the nozzle’s orifice is greatly affected when switching to or from R-22. Be very careful when working with those so-called drop-in refrigerants for ...TXV FUNCTIONALITY: 1+2: The thermostatic expansion valve (TXV) sensing bulb senses the temperature at the evaporator outlet. Based on that temperature, pressure in the sensing bulb increases or decreases. 3: The increased or decreased pressure is transmitted through the capillary tube to the top half of the power element. 4: …Bryan explains why and how to adjust a TXV and what to consider before doing it.
