York S1-025-31988-000 TXV

For technicians servicing legacy R-22 equipment, the York S1-025-31988-000 TXV is a precise OEM replacement designed to restore optimal superheat control. This 2-ton thermostatic expansion valve is engineered specifically for R-22 systems, featuring a 30-inch capillary tube and a 52# pressure rating to ensure accurate refrigerant metering and evaporator efficiency. As a genuine York replacement part, it eliminates the guesswork associated with universal valves, maintaining the equipment's original performance parameters and internal pressure balance.

Installation requires a professional focus on bulb placement and insulation to prevent hunting or slugging. The S1-025-31988-000 is an externally adjusted valve, allowing for fine-tuning of the superheat during the startup process to match specific field conditions. Whether you are performing a liquid line repair or a full coil restoration, using this OEM R-22 expansion valve ensures the HVAC system operates within its designated design envelope, protecting the compressor from liquid floodback while maximizing heat transfer across the evaporator fins.

• Precise Refrigerant Control: Specifically calibrated for R-22 2-ton systems to maintain consistent evaporator superheat.
• Extended Reach: Includes a 30-inch capillary tube for flexible remote bulb mounting and secure positioning.
• Durable Construction: Built for high-pressure HVAC applications with a 52# rating, ensuring long-term reliability in demanding environments.
• OEM Compatibility: Guaranteed fit for York technical specifications, reducing installation time and eliminating the need for complex field modifications.

Is the York S1-025-31988-000 compatible with R-410A systems?
No, this valve is specifically designed and calibrated for R-22 refrigerant only. Using it with R-410A will lead to improper metering and potential system failure.

How do I adjust the superheat on this York TXV?
This model features an adjustment stem. Increase superheat by turning the stem clockwise (reducing flow) or decrease it by turning counter-clockwise, allowing 15 minutes between adjustments for system stabilization.

What is the purpose of the 30-inch capillary on this expansion valve?
The capillary tube connects the sensing bulb to the valve body. Its 30-inch length provides the necessary reach to mount the bulb on the suction line outside of the cabinet or in tight evaporator configurations.
