York S1-4190 Expansion Valve

York S1-4190 Expansion Valve

For service technicians maintaining older R22 infrastructure, the York S1-4190 Expansion Valve provides critical metering precision for 2 to 3.5 ton HVAC systems. This thermostatic expansion valve (TXV) is engineered specifically for R22 refrigerant, ensuring high-efficiency heat transfer by maintaining consistent superheat across the evaporator coil. As a non-bleed expansion valve, the S1-4190 prevents refrigerant bypass during the off-cycle, which preserves system pressure differentials and aids in more efficient compressor startups. This OEM York replacement part features a brass body construction and a high-accuracy sensing bulb designed to respond rapidly to suction line temperature fluctuations, protecting the compressor from liquid slugging while maximizing cooling capacity.

Key Benefits:

  • Precise Refrigerant Metering: Optimized for 2-ton to 3.5-ton R22 systems to ensure peak evaporator efficiency.
  • Enhanced System Efficiency: The non-bleed design eliminates refrigerant migration during dwell periods, improving energy performance.
  • OEM Reliability: Direct York S1-4190 replacement ensures exact fitment and factory-standard performance characteristics.
  • Compressor Protection: Maintains optimal superheat levels to prevent liquid refrigerant from returning to the suction line.

Common Questions:

Is this TXV compatible with R410A systems?
No, this valve is specifically calibrated for the pressure/temperature relationship of R22 refrigerant. Using it with R410A will lead to improper metering and potential system failure.

What is the advantage of a non-bleed valve over a bleed-type TXV?
A non-bleed TXV like the S1-4190 provides a positive shut-off when the system is off, which prevents high-side and low-side pressures from equalizing. This is ideal for systems using hard-start kits to achieve maximum efficiency faster.

Will this valve fit a 3-ton evaporator coil?
Yes, the York S1-4190 is rated for a capacity range of 2 to 3.5 tons, making it a perfect match for 3-ton residential or light commercial air handlers and coils.
