Source1 2538739070 Thermal Expansion Valve Txv R410A 5 Ton 3/8 Inches Odm X 3/8 Inches Odf 90.0 Psig

Product Description

The SOURCE1 2538739070 is a thermal expansion valve, also called a TXV, designed for use with R410A refrigerant systems at a 5-ton capacity. This valve controls the flow of refrigerant into the evaporator coil by responding to changes in suction line temperature and pressure. When refrigerant enters the evaporator at the correct rate, the system maintains proper superheat and delivers consistent cooling performance. HVAC technicians rely on TXVs like this one to keep refrigerant-side efficiency at peak levels across a wide range of operating conditions. The 2538739070 features a 3/8 inches ODM inlet connection and a 3/8 inches ODF outlet connection, which match the factory specifications required for compatible York and Source1 equipment. The valve is rated to 90.0 PSIG, making it suited for the higher operating pressures common in R410A systems. Because this is a genuine OEM replacement part, it meets the exact design tolerances and material standards set during original equipment manufacturing. Using OEM components helps preserve full warranty coverage on the host unit, since aftermarket substitutes may not satisfy the factory installation criteria required for warranty eligibility. This valve is confirmed to fit popular models including J20L4EUA, HL8B060F4C, and HL5B060F3C. HVAC service professionals replacing a failed or underperforming TXV on compatible York split systems or heat pumps will find this part a direct, code-compliant solution. Proper TXV function prevents evaporator flooding, protects the compressor from liquid slugging, and ensures the system runs at rated efficiency. Installing the correct OEM valve reduces callback risk and keeps the system within designed operating parameters from the first startup after service.
