Trane 4AYTXVH3G4248A 3-4Ton Thermal Expansion Valve (TXV) R410A

The Trane 4AYTXVH3G4248A Thermal Expansion Valve is compatible with air conditioning and heat pump systems, which use R410A refrigerant and have a cooling capacity of 3-4 tons. As an expansion valve, it is involved with the feeling of the temperature and pressure of the refrigerant then regulating the flow of the refrigerant to achieve a correct superheat. This check ensures the refrigerant goes fully to the coil to enhance the cooling performance and ensure that the compressor does not receive damaging liquid refrigerant. This particular TXV is applied in residential and light commercial HVAC equipment including split systems and packaged units.
