York S1-025-27155-000 Expansion Valve

The York S1-025-27155-000 is an OEM thermal expansion valve (TXV) engineered to maintain precise refrigerant metering for residential and light commercial evaporator coils. Specifically designed for R-410A refrigeration systems, this valve utilizes a 3/8" ODM inlet and a 3/8" ODF outlet to ensure reliable sweat connections within the liquid line. As a veteran technician knows, accurate superheat control is critical for preventing compressor slugging and ensuring the evaporator operates at peak thermal efficiency. The S1-025-27155-000 York expansion valve balances pressure drops effectively, adapting to varying load conditions to keep the system within manufacturer-specified operating parameters.

• OEM Compatibility: Guaranteed fit for specific York, Luxaire, and Coleman air handlers and R-410A evaporator coils.
• Precise Flow Regulation: Maintains consistent evaporator superheat, protecting the compressor from liquid floodback.
• Durable Construction: Built with high-grade materials to withstand high-pressure 410A systems without premature bellows failure.
• Professional Grade: Features a 3/8" sweat connection (ODM/ODF) for leak-free brazed integration into the refrigerant line.

• What are the symptoms of a failing York TXV? Common indicators include frost on the evaporator, high superheat readings, or the AC system's inability to maintain setpoint temperatures despite proper airflow.
• Can this valve be used with R-22 systems? No, the York S1-025-27155-000 is calibrated exclusively for R-410A refrigerant and cannot be used in R-22 retrofits.
• Does this include the sensing bulb? Yes, this thermal expansion valve is supplied as a complete assembly, including the sensing bulb essential for monitoring suction line temperature.
