Description
The Sporlan Controls 125417 is a 20-ton thermostatic expansion valve (TXV) intended for use in air conditioning, refrigeration, and other HVAC systems that use R410A refrigerant. It is a crucial component that regulates the amount of liquid refrigerant that gets into the evaporator coil. By determining the temperature of the refrigerant vapor that is leaving the evaporator, the TXV controls the flow of liquid refrigerant. This keeps the superheat the difference between the refrigerant vapor’s actual temperature and its saturation temperature at the current pressure at a constant level. The TXV controls superheat to maintain ideal evaporator performance and avoid issues like loss efficiency and liquid flooding. This device is frequently used in industrial and commercial HVAC applications, including cold storage facilities, chillers, and big air conditioners.
