The HVAC TXV, which stands for Thermal Expansion Valve, is a precision-machined refrigeration component used in HVAC systems to control the amount of refrigerant that flows through the evaporator coil. The TXV is constantly making fine-tuned adjustments to control the temperature of your air conditioner coil.Dec 15, 2017 · TXVs are available with either internal or external pressure equalization (see Figure 5). Externally equalized valves are recommended for multi-circuit systems because they account for excessive pressure drops coming from distributors and through the evaporator—externally equalized valves sense the evaporator pressure from the equalizer line connected to the evaporator outlet.

The valve controls the refrigerant flow to the adjusted superheat in a continuous modulation, ensuring that the evaporator operates at its best. The TXV makes it possible for the enclosure air conditioner to run at its peak efficiency to handle the heat load. For a greater heat load, it can operate at higher capacities. A TXV is a device that regulates the flow of refrigerant into the evaporator based on real-time temperature feedback. It works by using a sensing bulb to detect the refrigerant temperature and adjust the valve opening, maintaining optimal superheat for efficient heat absorption. For satisfactory expansion valve control, good thermal contact between the bulb and suction line is essential. The bulb should be securely fastened with two bulb straps, supplied with each expansion valve, to a clean straight section of the suction line. Recommended suction line piping usually includes a horizontal line leaving the The thermostatic expansion valve performs the following functions: 1) Reduce the pressure of the refrigerant: The first and foremost function of the thermostatic expansion valve is to reduce the pressure of the refrigerant from the condenser pressure to the evaporator pressure.
