York S1-025-43272-000 Expansion Valve

The York S1-025-43272-000 is a field-adjustable thermal expansion valve (TXV) designed for precise refrigerant metering in York, Coleman, and Luxaire residential and light commercial systems. Featuring a 3/8 x 5/8 ODF connection, this unit facilitates a secure solder fit for high-pressure HVACR applications. As the direct replacement for S1-025-45297-000, it maintains consistent evaporator superheat, preventing liquid slugging and ensuring optimal compressor performance over the life of the system. The adjustable expansion valve design allows technicians to fine-tune refrigerant flow based on specific heat load demands, making it a critical component for stabilizing cooling cycles in split systems and package units. This HVAC refrigerant metering device is engineered for high-durability performance, ensuring thermal stability across varying ambient conditions. For contractors performing an OEM swap, this valve integrates directly into the liquid line, providing a reliable professional solution for restoring system efficiency and suction pressure stability without requiring extensive piping modifications.

• OEM Compatibility: Serves as the verified direct replacement for S1-025-45297-000 to ensure proper fitment.
• Adjustable Superheat: Allows for field calibration to meet exact manufacturer specifications for suction line temperature.
• ODF Solder Ports: Features a 3/8 x 5/8 ODF connection for standard brazing, reducing the risk of leaks compared to flare fittings.
• Reliable Metering: Prevents evaporator flooding and compressor damage by maintaining a precise refrigerant charge.
• Application Versatility: Suitable for use in a wide range of York-manufactured air handlers and evaporator coils.

What equipment is compatible with the York S1-025-43272-000?
This adjustable expansion valve is a certified service part for York, Coleman, and Luxaire evaporator coils. It is specifically designed to replace the legacy S1-025-45297-000 part number.

Is this a solder or flare connection TXV?
The valve utilizes a 3/8 x 5/8 ODF connection, meaning it is designed for a sweat/solder installation. Always use a wet rag on the valve body during brazing to protect internal components.

How do I set the superheat on this valve?
As an adjustable expansion valve, you can modify the superheat by removing the bottom cap and turning the adjustment stem. Clockwise turns increase superheat (reduces flow), while counter-clockwise turns decrease superheat (increases flow).
