York S1-025-40988-000 Valve
The York S1-025-40988-000 Thermal Expansion Valve (TXV) is a critical metering component engineered for precise refrigerant management in R-22 systems. Designed with a 55.0 PSIG pressure rating and 1/2 x 7/8 ODF sweat connections, this valve ensures stable superheat across a broad operating range, typically rated for temperatures between -40°F and 50°F. By dynamically modulating flow based on evaporator load, the S1-025-40988-000 prevents liquid floodback, protecting your compressor from mechanical failure while maximizing heat transfer efficiency in the evaporator coil. This OEM York replacement part features a durable brass body and reliable sensing bulb assembly, making it a standard choice for technicians servicing residential and light commercial split systems where maintaining tight pressure tolerances is essential for system longevity and thermal performance.
Key Benefits
- Precise Refrigerant Metering: Maintains consistent superheat to optimize evaporator coil efficiency and prevent slugging.
- OEM Standards: Genuine York HVAC part ensures exact fitment and pressure compatibility without the need for field modifications.
- Durable Construction: High-grade brass housing and robust internal components designed to withstand high-pressure HVACR environments.
- System Protection: Actively regulates flow to mitigate the risk of compressor damage caused by improper refrigerant distribution.
Common Questions
What are the symptoms of a failing York TXV?
Common indicators include high superheat, frosted evaporator coils, or erratic suction pressures, often leading to poor cooling capacity and increased compressor wear.
Is the S1-025-40988-000 compatible with R-410A?
No, this specific thermostatic expansion valve is calibrated for R-22 refrigerant applications. Using it with R-410A could lead to improper metering due to different pressure-temperature characteristics.
Does this valve require an external equalizer?
This model typically utilizes an internal sensing mechanism or specific external connection depending on the residential coil configuration; always verify your specific evaporator manifold requirements against the ODF sizing.
