Key Features
- OEM York replacement TXV — direct-fit for compatible York systems
- 3/8″ x 5/8″ ODF connections for straightforward field installation
- Rated for 3-ton (36,000 BTU/hr) system capacity
- 30″ sensing capillary tube for flexible bulb positioning
- Maintains consistent superheat to protect the compressor and maximize efficiency
- Precision-calibrated for stable refrigerant flow under varying load conditions
Why Use an OEM TXV?
Using a factory-specified TXV ensures the valve is matched to your system’s refrigerant type, operating pressures, and design superheat settings. Aftermarket substitutes may not deliver the same calibration accuracy, potentially leading to compressor slugging, poor efficiency, or premature component failure. The York S1-025-45287-000 is the correct OEM choice for maintaining system integrity and warranty compliance.
Application
- York residential and light commercial split-system air conditioners and heat pumps
