Description
The York S1-025-45300-000 is a genuine OEM Thermostatic Expansion Valve (TXV) engineered for precise refrigerant flow control in York residential and light commercial HVAC systems. Featuring 3/8″ liquid line and 5/8″ suction line ODF (Outside Diameter Flare) connections, this valve is designed as a direct factory replacement to restore peak system efficiency and maintain proper superheat control.
Why Thermostatic Expansion Valves Matter
The TXV is the heart of refrigerant metering in a split or packaged system. By modulating refrigerant flow in response to evaporator load, it maintains consistent superheat, protects the compressor from liquid slugging, and maximizes system efficiency across varying operating conditions. Replacing a worn or failed TXV with a genuine York part ensures the system performs exactly as designed.
