York S1-025-41339-000 TXV

The York S1-025-41339-000 is an OEM-grade 1.5 Ton Thermostatic Expansion Valve (TXV) engineered for precision refrigerant metering in residential and light commercial HVAC systems. Designed as a direct replacement part, this York thermal expansion valve features a 3/8x3/8 inch ODF connection and includes a 60-inch capillary tube, providing the necessary lead length for clean routing even in compact evaporator cabinets. By modulating the flow based on superheat, this valve ensures the evaporator maintains peak thermal exchange without risking liquid slugging to the compressor.

Field-verified for compatibility with specific York and Guardian air handlers and coils, including model CHGD42S41Q1, this 1.5-ton metering device is critical for maintaining system subcooling and overall SEER efficiency. Whether you are performing a liquid line repair or an evaporator coil overhaul, using a genuine York replacement TXV guarantees that the internal orifice and spring tension match the original manufacturer’s pressure drops and flow curves, preventing the hunting and uneven cooling often associated with universal aftermarket valves.

Key Benefits

• Optimized Refrigerant Control: Precisely manages the flow to the evaporator, maximizing efficiency across varying load conditions.
• OEM Fitment: Eliminates piping rework with a standard 3/8" x 3/8" connection and an ample 60-inch capillary line.
• System Reliability: Protects the compressor from liquid floodback by maintaining stable superheat levels.
• Broad Compatibility: Matches factory specifications for 1.5-ton York heating and cooling configurations.

Common Questions

How do I know if this TXV is failing?
Technicians typically look for signs of a "hunting" valve, where suction pressure fluctuates wildly, or a total blockage leading to extremely low suction pressure and high superheat. If the sensing bulb has lost its charge or the internal needle is stuck, replacing it with a York S1-025-41339-000 is the standard solution.

What is the purpose of the 60-inch capillary tube?
The extended length allows for flexible mounting of the sensing bulb on the suction line, ensuring it can be positioned at the proper "clock" location (usually 10 or 2 o'clock) even in tight plenum spaces.

Can this 1.5-ton TXV be used on a 2-ton system?
No. Metering devices must be matched to the system's tonnage and refrigerant type to ensure the evaporator is correctly flooded without overloading the compressor.
