York S1-025-41020-000 Expansion Valve

The York S1-025-41020-000 is an essential OEM 5 Ton Thermal Expansion Valve engineered for heavy-duty residential and commercial HVAC applications. Designed specifically for R-22 refrigerant systems, this thermostatic expansion valve (TXV) provides the precision metering required to optimize evaporator efficiency. Featuring 3/8" x 3/8" inlet and outlet connections, the S1-025-41020-000 utilizes a 31" capillary tube and a remote sensing bulb to monitor suction line temperature, ensuring a constant superheat and preventing liquid floodback—a critical factor in extending compressor life. Whether performing a drop-in replacement on a York BCUP-F060A model or troubleshooting low-side pressure issues, this HVAC expansion valve 5 ton assembly offers the mechanical reliability needed for high-demand environments. Its robust construction ensures stable refrigerant flow regulation under varying load conditions, maintaining systemic balance and peak cooling performance across the entire evaporator coil surface.

• Precise Refrigerant Metering: Delivers exact R-22 dosing for 5 ton HVAC systems, maximizing heat transfer and efficiency.
• System Protection: Actively manages superheat to prevent liquid slugging from damaging the compressor.
• Direct OEM Fit: Guaranteed compatibility with specific York and Johnson Controls equipment, including the BCUP-F060A series.
• Extended Capillary Reach: The 31-inch capillary tube allows for versatile bulb placement on the suction line.
• Durable Connection Points: Standard 3/8" x 3/8" fittings facilitate a secure, leak-resistant installation.

Is the York S1-025-41020-000 compatible with R-410A?
No, this valve is strictly engineered for R-22 refrigerant. Using it with R-410A will result in incorrect pressure regulation and potential system failure.

What are the symptoms of a failing expansion valve?
Common signs include frost on the evaporator coil, high superheat readings, and the compressor running constantly without reaching the set temperature.

Does this TXV include the sensing bulb?
Yes, the York S1-025-41020-000 features a factory-integrated 31" capillary and sensing bulb for immediate installation.
