York S1-025-43228-000 Expansion Valve
The York S1-025-43228-000 Expansion Valve is a critical OEM replacement part engineered for precise refrigerant metering in R410A refrigeration systems. Designed specifically for BAUQ series heat pumps, this thermostatic expansion valve (TXV) modulates flow based on evaporator load to prevent liquid slugging and optimize superheat levels. Featuring 3/8x3/8 ODF connections, the S1-025-43228-000 ensures a secure, leak-resistant brazed fit within the liquid line. As a genuine York HVAC part, it maintains the structural integrity of the evaporator coil assembly, ensuring the system operates within manufacturer-specified pressure parameters. For technicians servicing 3-ton residential or commercial packaged units, utilizing this specific metering device is essential for restoring factory-standard cooling efficiency and maintaining proper subcooling. Its robust internal diaphragm and needle assembly are calibrated for the high-pressure demands of R410A systems, providing stable performance across varying ambient conditions.
Key Benefits- Specifically calibrated for York BAUQ series 3-ton heat pumps to ensure exact port sizing and flow rates.
- Features 3/8 inch ODF solder connections for standardized installation in common liquid line configurations.
- Optimized for R410A refrigerant to provide accurate superheat control and protect the compressor from liquid carryover.
- Direct OEM replacement ensures physical compatibility with existing evaporator coil mounting brackets and sensing bulb locations.
Is the S1-025-43228-000 compatible with older R22 systems?
No, this TXV is specifically designed and calibrated for the pressure-temperature characteristics of R410A refrigerant. Using it in an R22 system will result in improper metering and potential system failure.
What are the specific connection sizes for this York expansion valve?
This valve features 3/8" x 3/8" ODF (Outside Diameter Female) connections, which are designed for brazing directly onto 3/8" copper tubing.
Does this valve include the sensing bulb and mounting hardware?
This York S1-025-43228-000 is typically supplied with the integrated thermal sensing bulb required for monitoring evaporator outlet temperature.
