York S1-1TVM4H1 TXV
The York S1-1TVM4H1 TXV is a precise HVAC metering device engineered for 4-ton residential and light commercial cooling systems. This R-410A expansion valve features 5/8" x 5/8" sweat connections, designed to handle the high operating pressures of modern refrigerants while maintaining a leak-free seal. As a genuine York OEM replacement part, it ensures exact compatibility with existing evaporator coils, eliminating the mounting headaches often associated with universal aftermarket components. The 30" capillary tube provides ample length for proper sensing bulb placement on the suction line, which is critical for accurate superheat regulation. Installing this 4-ton thermostatic expansion valve allows for optimal evaporator flooding, protecting the compressor from liquid slugging and preventing evaporator freeze-ups. For service technicians, utilizing this factory-spec component is essential for restoring system SEER ratings and ensuring consistent refrigerant flow across varying thermal loads.

QUESTIONS & ANSWERS
Ask a Question-
I have york FC48C3XN1H unit with R22 or R410A refrigerant. I am planning to change old condenser to GOODMAN model # GSX140481. Can I use this TXV valve or do you have any TXV valve which I can use.
Since you are installing a new Goodman condenser to work with the old York furnace we suggest you let the contractor get the part they want locally and decide what they want to use so they can guarantee their work.
