York S1-025-39911-000 Expansion Valve
The York S1-025-39911-000 Expansion Valve is a precise OEM thermostatic metering device designed for 3-ton R-22 refrigeration systems. This thermostatic expansion valve (TXV) utilizes a 3/8" x 3/8" connection and features a 30-inch capillary tube to ensure accurate superheat regulation across varying thermal loads. As a direct OEM replacement part, it maintains factory-spec refrigerant flow, preventing liquid slugging and evaporator starving. For technicians servicing legacy York or Luxaire equipment, this R-22 expansion valve is a critical component for restoring system efficiency and protecting the compressor from premature failure. The bolt-on TXV design allows for a cleaner integration into the distributor assembly, and its 3-ton capacity is specifically calibrated for residential and light commercial evaporator coils. High-grade brass construction and a durable sensing bulb assembly provide the reliability required for HVACR system maintenance and high-pressure R-22 environments. Use this genuine York HVAC part to ensure optimal saturation temperatures and consistent cooling performance.
Key Benefits:- Precise Refrigerant Metering: Optimized for 3-ton R-22 systems to maintain consistent superheat and prevent evaporator frosting.
- OEM Compatibility: Genuine York S1-025-39911-000 replacement ensures exact fitment and factory-standard performance.
- Durable Construction: Features a robust brass body and a 30” capillary sensing bulb for longevity in demanding HVAC environments.
- Compressor Protection: Effectively manages refrigerant flow to eliminate high discharge temperatures and technical failures.
- Technical Specifications: Standard 3/8" x 3/8" inlet and outlet connections for straightforward field installation.
Can I use this TXV on a 4-ton R-22 system?
No, this valve is fixed for 3-ton capacity. Using an undersized expansion valve will starve the evaporator, resulting in high superheat and reduced cooling capacity.
Is this compatible with R-410A refrigerant?
This specific model is calibrated for R-22 refrigerant only. The internal spring tension and orifice sizing are not designed for the higher operating pressures of R-410A.
Where should the sensing bulb be mounted?
The sensing bulb should be securely clamped to a horizontal run of the suction line, ideally at the 2 o'clock or 10 o'clock position, and fully insulated to ensure accurate temperature readings.
