York S1-1TVM702 TXV Kit
The York S1-1TVM702 R22 TXV Kit is an essential OEM replacement component designed to restore precise refrigerant metering in legacy R-22 residential and light commercial systems. Engineered for high-side installation on indoor flex coils, this thermal expansion valve (TXV) utilizes an internal check valve, making it suitable for both straight-cool and heat pump applications. By modulating the flow of R-22 refrigerant based on evaporator load, the S1-1TVM702 ensures optimal superheat and prevents liquid slugging, which is critical for protecting the compressor on older equipment. This bolt-on kit simplifies field repairs and includes a calibrated sensing bulb, mounting straps, and thermal insulation to ensure accurate temperature sensing. This kit is compatible with specific York and Johnson Controls models, including the AC2A036 and HC2A042 series. Using genuine York HVAC parts ensures that the system maintains original factory performance ratings and oil return reliability.
Key Benefits- Optimized Refrigerant Control: Maintains consistent superheat to maximize evaporator efficiency across varying load conditions.
- Dual-Mode Functionality: Integrated check valve allows for seamless operation in both heating and cooling cycles.
- Field-Serviceable Design: Bolt-on configuration minimizes downtime and simplifies the replacement process compared to sweat-in alternatives.
- System Protection: Precisely regulates R22 refrigerant flow to prevent evaporator icing and potential compressor damage.
- Complete Installation Package: Includes necessary mounting hardware and 2.5 feet of thermal insulation for immediate field deployment.
Is the York S1-1TVM702 compatible with R-410A systems?
No, this specific kit is calibrated strictly for R-22 refrigerant. Using it with R-410A will lead to improper metering and potential system failure due to different pressure-temperature relationships.
What are the symptoms of a failing TXV on a York unit?
Common indicators include inconsistent evaporator temperatures, high superheat, frost buildup on the indoor coil, or the system frequently "hunting" for stable operating pressures.
Where should the sensing bulb be mounted?
The sensing bulb should be secured to a horizontal run of the suction line at the 10 o'clock or 2 o'clock position to ensure it reads vapor temperature rather than oil or liquid lying at the bottom of the pipe.
