York S1-VLV-002-410 Expansion Valve
The York S1-VLV-002-410 Expansion Valve is a specialized HVAC OEM replacement part designed for precision refrigerant metering in high-efficiency systems. As a thermostatic expansion valve (TXV), it utilizes an Alco power assembly to modulate R-410A refrigerant flow, ensuring the evaporator maintains optimal superheat under varying thermal loads. This specific 3-ton TXV features 3/8 x 1/2 ODF connections (Outside Diameter Flare) for secure, brazed installation, preventing the common leaks associated with mechanical fittings in high-pressure cycles. By preventing liquid slugging and evaporator flooding, the York S1-VLV-002-410 preserves compressor longevity and stabilizes suction-line pressures across residential and light-commercial split systems. The integrated sensing bulb and 1/8-inch equalizer line work in tandem to provide reactive feedback, making this thermal expansion valve essential for maintaining SEER ratings and peak system capacity during extreme ambient temperatures.
Key Benefits for Technicians- Precise Superheat Control: Features a high-response sensing bulb to maintain exact refrigerant levels, preventing evaporator icing and compressor flooding.
- R-410A Optimization: Specifically calibrated for high-pressure R-410A systems to maximize heat transfer efficiency.
- Durable Alco Power Assembly: Utilizes a rugged Alco head design to resist diaphragm fatigue and ensure consistent modulation over the system lifetime.
- Streamlined Installation: The 3/8 x 1/2 ODF sweat connections provide a standard fit for consistent brazing in tight evaporator cabinets.
- OEM Compatibility: Guaranteed fit for York, Luxaire, and Coleman air handlers and heat pumps requiring the S1-VLV-002-410 spec.
Is the York S1-VLV-002-410 compatible with R-22 systems?
No, this valve is internally calibrated and valved specifically for R-410A refrigerant. Using it in R-22 equipment will result in improper superheat and potential system damage.
What are the signs of a failing S1-VLV-002-410 expansion valve?
Common indicators include frost formation on the evaporator coil, high superheat readings, or the compressor short-cycling due to low suction pressure caused by a "stuck closed" orifice.
Does this TXV include the sensing bulb and mounting hardware?
Yes, this genuine York TXV kit includes the valve body with an integrated sensing bulb and capillary tube for a complete field replacement.
