York S1-025-47302-000 Expansion Valve

The York S1-025-47302-000 Expansion Valve is a critical metered flow control component engineered for high-performance 2-ton R410A systems. Built for precision refrigerant management, this thermostatic expansion valve (TXV) maintains the optimal superheat at the evaporator outlet, protecting the compressor from liquid slugging while maximizing heat transfer efficiency. Featuring 3/8-inch ODM x 3/8-inch ODF connections, this brass-body valve ensures a reliable, leak-resistant fit in residential and light commercial evaporator coils. As a genuine OEM York replacement part, the S1-025-47302-000 is designed to meet strict factory specifications, ensuring seamless compatibility and system balance without the need for field modifications. Whether you are performing a seasonal upgrade or a critical system repair, utilizing a factory-spec R410A thermal expansion valve is essential for maintaining SEER ratings and preventing premature component fatigue in modern high-pressure HVAC environments.

• Optimized Refrigerant Control: Regulates R410A flow precisely to match cooling demand, ensuring consistent evaporator performance.
• Compressor Protection: Maintains proper superheat levels to prevent liquid refrigerant from returning to the compressor.
• Direct OEM Fit: Specifically engineered for York, Luxaire, and Coleman equipment to ensure 3/8" ODM x 3/8" ODF line set compatibility.
• System Efficiency: Minimizes energy consumption by preventing over-metering and under-metering during varying thermal loads.

Is the S1-025-47302-000 compatible with older R22 systems?
No, this valve is strictly calibrated for R410A refrigerant and 2-ton capacities. Using it with R22 will result in improper superheat and potential system failure.

What are the connection sizes for this York TXV?
This model features 3/8-inch Outside Diameter Male (ODM) and 3/8-inch Outside Diameter Female (ODF) connections for specialized fitment in 2-ton coils.

Do I need to wrap the valve body during installation?
Yes, when brazing the 3/8-inch connections, always use a wet rag or heat-sink paste to protect the internal components and diaphragm from heat damage.
