York S1-1TVM4J1 Expansion Valve

The York S1-1TVM4J1 Expansion Valve is a precision-engineered 5-ton thermostatic expansion valve (TXV) designed for R410A refrigerant applications. As an OEM York replacement part, this externally equalized TXV ensures optimal superheat control across varying load conditions, preventing liquid slugging and protecting the compressor. Featuring a 5/8" male x 5/8" female flare connection and a 30-inch capillary tube, the S1-1TVM4J1 provides the mechanical accuracy required to maintain the evaporator's efficiency in high-demand residential and commercial HVAC systems. For contractors performing a York TXV kit installation, this valve facilitates a direct fit, streamlining the R410A expansion valve replacement process and restoring the system’s engineered cooling capacity.

Key Benefits

• Precision Flow Control: Engineered for 5-ton capacity to maintain stable evaporator temperatures.
• Broad Compatibility: Direct OEM replacement for various York, Coleman, and Luxaire air handlers and evaporator coils.
• Durable Construction: Features a high-grade 30" capillary and sensing bulb for responsive pressure regulation.
• Installation Efficiency: Utilizes standard 5/8" flare connections to reduce field brazing and labor time.

Common Questions

Does this valve require an external equalizer line?
Yes, this is an externally equalized valve with a 1/4" connection, vital for accurate pressure sensing in larger 5-ton systems with high pressure drops.

Can I use this TXV with R-22 systems?
No, the S1-1TVM4J1 is specifically calibrated and charged for R410A systems and cannot be used with other refrigerants.

Is the sensing bulb hardware included?
The kit typically includes the mounting clamp and thermal insulation tape required to secure the 30" capillary bulb to the suction line.
