York S1-025-30209-700 TXV

The York S1-025-30209-700 TXV is a precision-engineered thermal expansion valve designed for high-capacity 5.5-ton residential and light commercial evaporator coils. This OEM thermostatic controller utilizes a 1/2" x 5/8" sweat connection to ensure leak-free integration within high-pressure R-410A systems. Featuring a 60-inch capillary tube, the unit provides extensive reach for remote sensing bulb placement, allowing for accurate superheat adjustments and optimal refrigerant metering across varying load conditions. For technicians servicing York, Luxaire, or Coleman equipment, this 5.5-ton TXV is essential for maintaining system efficiency and protecting the compressor from liquid slugging. The robust brass body and stainless steel power element are built to handle the rigorous demands of HVAC refrigeration cycles, ensuring stable evaporator pressures and consistent cooling performance in demanding climates.

Key Benefits:

• Compatible with high-tonnage 5.5-ton HVAC systems requiring precise refrigerant flow control.
• Features 1/2" inlet and 5/8" outlet sweat fittings for standard copper line set brazing.
• Integrated 60-inch capillary lead for flexible sensing bulb mounting on the suction line.
• Maintains optimal superheat to maximize evaporator efficiency and prevent compressor damage.
• Genuine York replacement part ensures exact fitment and OEM-level performance for York-family brands.

Common Questions:

What refrigerant is the S1-025-30209-700 compatible with?
This valve is specifically calibrated for use in R-410A systems, managing the higher operating pressures associated with modern high-efficiency cooling units.

Can I use this TXV on a 5-ton system?
While sized for 5.5 tons, HVAC technicians must verify the specific coil match and orifice requirements. It is generally used in systems rated up to 5.5 tons to ensure the evaporator is not starved during peak loads.

Does this include the sensing bulb mounting hardware?
The assembly typically includes the valve body and the attached 60" capillary with sensing bulb; however, field technicians often use standard copper straps for the most secure thermal contact on the suction line.
