York S1-022-08912-000 Expansion Valve

The York S1-022-08912-000 Expansion Valve is a 10-ton capacity thermostatic expansion valve (TXV) engineered for R22 refrigerant systems. Designed with a straight body configuration and 5/8" x 1 1/8" ODF sweat connections, this component ensures precise refrigerant metering across varying evaporator loads. The inclusion of a 1/4" external equalizer allows the valve to compensate for pressure drops within the evaporator coil, maintaining optimal superheat and protecting the compressor from liquid slugging. Built with a 60-inch capillary tube, it provides necessary flexibility for bulb placement in large-scale light commercial or heavy residential York, Luxor, and Coleman air handling units. This HVAC replacement TXV is a direct OEM match for specific multi-stage cooling systems, ensuring that system modulation remains stable under high-demand cycles. Utilizing an external sensing bulb, the York S1-022-08912-000 provides the responsive thermal feedback required to maintain high system efficiency and consistent discharge air temperatures.

• Precise Superheat Control: Externally equalized design prevents hunting and maintains stable evaporator performance in high-tonnage applications.
• 10-Ton R22 Capacity: Specifically calibrated for high-capacity cooling systems requiring 120,000 BTU/h nominal ratings.
• OEM Compatibility: Exact drop-in replacement for York S1-022-08912-000, ensuring matched port sizing and pressure profiles.
• Extended Reach: The 60-inch capillary lead allows for proper sensing bulb positioning on the suction line, even in cramped cabinet configurations.
• Durable Construction: High-grade brass body and stainless steel power element designed for long-term vibration resistance.

What are the connection sizes for this York TXV?
This valve features a 5/8" ODF inlet and a 1 1/8" ODF outlet, both designed for sweat/solder installation. It also includes a 1/4" external equalizer line.

Can I use this valve on an R410A system?
No, the York S1-022-08912-000 is specifically charged and calibrated for R22 refrigerant. Using it with R410A will result in incorrect superheat levels and potential system failure.

Where should the sensing bulb be mounted?
The bulb should be securely fastened to a horizontal section of the suction line, ideally at the 4 or 8 o'clock position, and properly insulated to ensure accurate temperature readings for the thermal expansion valve.
