York S1-025-41178-000 Expansion Valve

The York S1-025-41178-000 Expansion Valve is a critical OEM replacement component engineered for 3-ton residential and light commercial condensing units. This thermostatic expansion valve (TXV) is specifically calibrated for R-22 refrigerant, utilizing a 3/8" x 3/8" connection size to ensure precise metering and optimal superheat control. For contractors managing R-22 legacy systems, this valve provides the exact pressure drop required to maintain evaporator efficiency and prevent liquid slugging, which is vital for the longevity of the compressor.

Built for compatibility with York and Source 1 equipment, including model BBUP-F036A, the York S1-025-41178-000 features a robust design that manages fluctuating heat loads effectively. As a genuine HVAC replacement part, it eliminates the sizing risks associated with universal aftermarket valves. Integrating this 3 ton TXV into your service workflow ensures that the system operates within peak thermal parameters, preserving cooling capacity in high-ambient conditions. Expert installation is required to ensure proper bulb placement and capillary line routing for accurate sensing.

• OEM Precision: Guaranteed compatibility with 3-ton York condensing units to maintain factory specifications.
• R-22 Optimization: Specifically designed for legacy R-22 refrigerant systems requiring precise flow regulation.
• Durable Construction: High-grade materials resist corrosion and mechanical wear in demanding HVACR environments.
• Standardized Fit: 3/8x3/8 TXV connections allow for straightforward integration into existing liquid lines.
• Enhanced Efficiency: Precise superheat management prevents evaporator flood-back and maximizes system performance.

What are the symptoms of a failing S1-025-41178-000 valve?
Technicians typically observe high superheat, low suction pressure, or frost on the evaporator coil, indicating restricted refrigerant flow or a lost power element charge.

Is this valve compatible with R-410A systems?
No, this specific thermostatic expansion valve is calibrated for the pressure-temperature characteristics of R-22 and should not be used in R-410A applications.

Does this TXV include the sensing bulb?
Yes, this is a complete York S1-025-41178-000 assembly designed for proper thermal feedback from the suction line.
