Description
The York S1-022-12989-000 is an OEM thermostatic expansion valve (TXV) engineered specifically for R-410A refrigerant systems. Designed and manufactured to York’s exacting standards, this TXV precisely meters refrigerant flow into the evaporator coil, maintaining optimal superheat levels and maximizing system efficiency across a wide range of operating conditions.
Why the TXV Matters
A properly functioning thermostatic expansion valve is critical to the performance and longevity of any split or packaged HVAC system. By continuously modulating refrigerant flow in response to evaporator load changes, the TXV prevents both liquid slugging and excessive superheat — protecting the compressor and ensuring consistent comfort delivery.
Key Features

- OEM York replacement part — engineered to match original factory specifications
- Precise superheat control for optimized system efficiency and compressor protection
- Direct drop-in replacement for compatible York residential and light commercial equipment
- Durable construction built to withstand the elevated operating pressures of R-410A systems
- Helps maintain proper evaporator coil performance and system capacity
Application
- Compatible with York R-410A split system air conditioners and heat pumps
- Intended as a direct OEM replacement — consult your equipment model documentation to confirm fitment
Why Choose an OEM TXV?
Aftermarket valves may not match the calibrated superheat settings required by your specific York equipment. Using the genuine York S1-022-12989-000 ensures the valve is factory-calibrated for your system’s refrigerant charge, coil design, and operating pressures — reducing callbacks and ensuring warranty compliance.
