York S1-025-32798-036 TXV

The York S1-025-32798-036 is a professional-grade 5-ton R-22 thermostatic expansion valve designed for precision refrigerant metering in residential and light commercial evaporator coils. Engineered with a 3/8” ODF inlet and a 1/2” ODF outlet, this TXV replacement ensures optimized superheat control across varying load conditions. It features a 30-inch capillary tube for flexible sensing bulb placement, allowing for accurate feedback into the power assembly. This OEM York HVAC part is a direct replacement for aging or restricted expansion valves in R-22 systems, preventing liquid slugging and ensuring the compressor operates within design parameters. For technicians performing a York AC repair, this valve provides the reliability needed to restore system efficiency and Delta T performance. The balanced port design compensates for pressure drops, making it a critical component for maintaining the seasonal energy efficiency ratio of legacy cooling units.

Key Benefits

• Direct OEM Fit: Drop-in compatibility for 5-ton York, Luxaire, and Coleman R-22 evaporator coils.
• Precision Superheat Control: Maintains consistent refrigerant flow to maximize heat transfer across the coil.
• Durable Construction: High-grade brass body and stainless steel power element resist corrosion and provide long-term reliability.
• Extended Capillary: The 30-inch lead allows for optimal sensing bulb positioning on the suction line.

Common Questions

How do I know if this TXV is failing?
Common indicators include high superheat, low suction pressure, or frost formation on the expansion valve inlet while the system is undercharged or showing normal head pressure.

Is this valve compatible with R-410A systems?
No, the York S1-025-32798-036 is specifically calibrated for R-22 refrigerant pressures and flow characteristics. Using this on an R-410A system will result in improper metering and potential compressor damage.

Does this valve include the sensing bulb insulation?
Standard installations require the sensing bulb to be insulated against ambient air to ensure accurate temperature readings from the suction line; always verify bulb contact before securing.
