York 025-40666-000 Expansion Valve

Maintaining precise refrigerant metering is critical for system longevity and efficiency. The York 025-40666-000 is an OEM Thermostatic Expansion Valve (TEV) engineered specifically for high-capacity HVACR refrigeration services. Featuring a durable brass body and an adjustable differential, this valve provides technician-level control over superheat settings to prevent liquid slugging and evaporator icing. With a 1-1/8" inlet and 1-3/8" outlet, it is designed for seamless integration into commercial split and package systems, ensuring the evaporator coil receives the exact refrigerant flow required for optimal cooling capacity under varying thermal loads. As a genuine Johnson Controls part, this replacement expansion valve eliminates the compatibility risks associated with universal aftermarket components, maintaining the integrity of the original system design and protecting the compressor from premature failure due to erratic pressure fluctuations.

• Adjustable Superheat Control: Allows for field-tuning to match specific ambient conditions and load requirements.
• OEM Construction: High-grade brass housing ensures refrigerant pressure regulation and corrosion resistance in demanding environments.
• Optimized Flow Dynamics: Precision-machined 1-1/8" x 1-3/8" connections reduce pressure drop and improve HVAC system efficiency.
• Superior Reliability: Built to withstand the rigorous cycling of commercial refrigeration and air conditioning units.

• What are the symptoms of a failing York 025-40666-000 valve? Common failure signs include a frozen evaporator coil, erratic suction pressures, and high superheat readings.
• Is this expansion valve compatible with different refrigerants? This York expansion valve is a specific OEM replacement; always verify your unit's data plate and refrigerant type before installation to ensure performance.
• Does this part require a new filter drier? Best trade practices recommend replacing the liquid line filter drier whenever the refrigerant circuit is opened to prevent debris from clogging the new TEV valve.
