York S1-1TVM4K1 TXV

The York S1-1TVM4K1 is a proactive metering solution engineered for high-capacity 6-ton HVAC systems. Designed specifically for R410A refrigerant applications, this thermostatic expansion valve (TXV) optimizes the liquid refrigerant flow into the evaporator coil by maintaining precise superheat levels. It features 5/8" x 5/8" connections and is equipped with a 30-inch capillary tube, allowing for flexible bulb placement and accurate temperature sensing even in tight cabinet configurations. As a genuine OEM York replacement part, this 6-ton TXV kit ensures seamless integration with compatible York, Luxaire, and Coleman air handlers or indoor coils. The mechanical design prevents evaporator flooding and compressor slugging, making it a critical component for maintaining high SEER ratings and stable suction pressures during fluctuating load conditions. For technicians performing an AC expansion valve replacement, the S1-1TVM4K1 provides the reliability required for light commercial and large-scale residential split systems.

Key Benefits:

• Precision Refrigerant Control: Maintains exact superheat to maximize heat exchange efficiency across the evaporator.
• OEM Compatibility: Guaranteed fit for York S1-1TVM4K1 specifications, eliminating the need for field modifications.
• Heavy-Duty Capacity: Specifically rated for 6-ton R410A systems, providing the high flow rate needed for large tonnage units.
• System Protection: Actively prevents liquid refrigerant from returning to the compressor, extending the life of the primary cooling components.
• Extended Reach: The 30" capillary tube provides ample lead length for proper sensing bulb positioning on the suction line.

Common Questions:

What are the signs that a 6-ton TXV needs to be replaced?
Technicians typically look for hunting pressures, high superheat with low suction pressure, or frost formation on the expansion valve body, all of which indicate a restricted or failing York expansion valve.

Is the S1-1TVM4K1 compatible with R22 systems?
No, this valve is strictly calibrated for R410A refrigerant. Using it with R22 will result in improper refrigerant metering and potential system failure.

Does this kit include the sensing bulb clamps?
Yes, this professional-grade kit typically includes the necessary hardware for securing the sensing bulb to the vapor line to ensure accurate thermal feedback.
