York 025-40900-003 TXV

The York 025-40900-003 TXV is a heavy-duty 31-ton thermal expansion valve engineered for critical refrigerant metering in large-scale commercial and industrial R410A HVAC systems. As a veteran technician knows, maintaining precise superheat is vital for evaporator coil efficiency and protecting the compressor from liquid slugging. This OEM York replacement part features a 1-1/8" ODF sweat connection, ensuring a secure, leak-free braze into high-capacity liquid lines. Designed specifically for the high-pressure environment of R410A systems, the 025-40900-003 provides the responsive flow regulation needed for multi-circuit chillers and rooftop units. Whether performing a TXV replacement or a system overhaul, utilizing this original equipment manufacturer component ensures the HVAC expansion valve matches the factory-specified performance curves for York cooling equipment. Its robust construction is built to handle the rigorous duty cycles of 31-ton nominal capacity units, maintaining system stability across varying load conditions without the hunting issues common in generic alternatives.

• Precise Superheat Control: Optimizes refrigerant flow to maximize heat transfer across the evaporator coil.
• Industrial Capacity: Rated for 31-ton cooling applications, making it ideal for large tonnage York chillers and commercial RTUs.
• Secure ODF Connections: Standard 1-1/8" ODF sweat fittings facilitate professional-grade installation in the field.
• OEM Compatibility: Precision-matched for York HVAC systems to eliminate compatibility errors during HVAC refrigeration parts sourcing.
• R410A Optimized: Built to withstand the specific pressure and temperature requirements of modern air conditioning refrigerants.

Is the York 025-40900-003 compatible with R22 systems?
No, this valve is specifically calibrated for R410A refrigerant and its associated high-pressure operating ranges. Using it with R22 will lead to incorrect metering and potential equipment damage.

What is the connection type for this 31-ton TXV?
The valve utilizes a 1-1/8" ODF (Open Diameter Female) sweat connection, requiring standard copper brazing techniques for installation.

Should I replace the filter drier when installing this new expansion valve?
Yes, it is standard professional practice to replace the liquid line filter drier whenever the refrigerant circuit is opened to prevent moisture and debris from clogging the TXV orifice.
