York S1-025-39910-000 Expansion Valve

The York S1-025-39910-000 is an OEM 6 Ton TXV (Thermostatic Expansion Valve) specifically engineered for equipment operating with R-22 refrigerant. This critical metering device maintains precise superheat levels by regulating the liquid refrigerant flow into the evaporator, preventing compressor slugging while maximizing cooling efficiency. Designed with 3/8 x 3/8 connections (ODM x ODF), it facilitates a secure, leak-resistant integration into existing line sets. The inclusion of a 30-inch capillary tube allows for flexible sensing bulb placement, ensuring accurate thermal feedback even in tight cabinet configurations. Rated for a nominal pressure of 80.6 PSI, this valve is a standard requirement for maintaining optimal evaporator saturation in large-scale residential or light commercial split systems. For technicians performing HVAC R-22 valve replacement, utilizing this genuine York expansion valve ensures matched port sizing and pressure drops, maintaining the original system performance curve without the risks associated with universal aftermarket components.

• OEM Compatibility: Exact drop-in replacement for York, Luxaire, and Coleman 6-ton cooling systems.
• Precise Superheat Control: Regulates refrigerant flow to protect the compressor and optimize coil surface utilization.
• Durable Construction: Built with corrosion-resistant materials to withstand high-pressure R-22 environments.
• Installation Flexibility: The 30" capillary length simplifies bulb positioning for accurate suction line temperature sensing.

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

What are the connection sizes?
The valve features a 3/8" inlet and a 3/8" outlet, utilizing standard ODM x ODF connection types for secure brazing.

Does this fit all 6-ton units?
While designed for 6-ton capacities, always verify the specific part number and connection requirements of your evaporator coil before installation.
