York S1-022-06844-052 Metering Device

The York S1-022-06844-052 is a precision-engineered refrigerant metering device designed specifically for integration with OEM York and Johnson Controls evaporator coils. This HVAC replacement part facilitates accurate flow control, ensuring the pressure drop across the liquid line and evaporator remains within strict factory tolerances. Built to withstand the high-pressure environment of R-410A systems, this component eliminates the variability often found in universal orifices, preventing common issues such as liquid slugging or uneven coil loading. For technicians performing a system restoration or coil repair, installing this genuine metering device is critical for maintaining engineered superheat levels and optimizing system delta-T. Its robust construction ensures long-term resistance to flash-gas erosion, providing the mechanical reliability required for commercial and residential applications where precise thermal regulation is non-negotiable. Using this specific part ensures the air handler or coil assembly operates at its rated SEER efficiency without the risk of localized hotspots.

Key Benefits for Technicians

• OEM Precision: Guaranteed compatibility with York and Johnson Controls equipment, eliminating the guesswork of universal sizing.
• Optimized Flow Control: Maintains exact refrigerant distribution across all coil circuits for uniform heat absorption.
• R-410A Rated: Designed to handle the thermal and pressure demands of modern high-efficiency refrigerants.
• Thermal Stability: Critical for achieving precise superheat and subcooling measurements during system commissioning.

Common Technical Questions

Is the S1-022-06844-052 compatible with older R-22 systems?
This component is specifically calibrated for the flow characteristics and pressure requirements of R-410A systems; always verify the orifice size against the equipment nameplate data before installation.

What are the symptoms of a failing metering device in a York system?
Technicians typically observe abnormal suction pressures, evaporator icing, or hunting behavior during the cooling cycle, indicating that the refrigerant flow is no longer meeting factory specifications.

Does this part require specific orientation during brazing?
While the device itself is bi-directional in some distributor assemblies, it is vital to ensure it is seated correctly within the distributor body to prevent bypass leaks or turbulence.
