York S1-022-09092-000 Expansion Valve

The York S1-022-09092-000 Expansion Valve is a critical OEM replacement part engineered for high-performance HVAC refrigerant metering in 4 to 5-ton heat pump systems. Designed specifically for R-22 refrigerant, this thermostatic expansion valve (TXV) maintains precise superheat throughout varying load conditions, ensuring optimal evaporator efficiency. This valve features 3/8 inch ODM x 3/8 inch ODF connections and a 30-inch capillary tube for flexible sensing bulb placement. For technicians servicing York E1RD series units, hardware matching is straightforward as this component is the factory-specified solution for models like the E1RD048S25A and E1RD048S46A. Utilizing a genuine York 4-5 ton TXV prevents the common issues of liquid slugging or evaporator starving often seen with generic universal valves. By regulating flow with technical precision, this valve protects the compressor and stabilizes system pressures in legacy R-22 equipment.

• Direct OEM Compatibility: Ensures a perfect fit for York E1RD heat pumps, eliminating the need for field modifications or secondary adapters.
• Precise Superheat Control: The 30-inch sensing lead provides accurate thermal feedback across a 4 to 5-ton range for consistent cooling.
• System Reliability: Protects against compressor failure by maintaining strict refrigerant flow rates in R-22 residential systems.
• Optimized Heat Transfer: Prevents evaporator flood-back, maximizing the efficiency of the heat exchange process in older high-capacity units.

What are the connection sizes for the S1-022-09092-000?
This TXV uses 3/8-inch inlet and 3/8-inch outlet connections, specifically designed for a sweat-in installation on standard liquid lines.

Can this valve be used with R-410A systems?
No, this expansion valve is calibrated specifically for the pressure-temperature characteristics of R-22 refrigerant and is not cross-compatible with R-410A.

Is the sensing bulb hardware included?
The valve includes the integrated 30-inch capillary sensing tube required for monitoring suction line temperature to regulate the internal diaphragm.
