Lennox 26K49 TXV
The Lennox 26K49 Thermostatic Expansion Valve (TXV) is a critical metering component engineered specifically for 3-ton R22 refrigerant systems utilizing a B10 flowrater configuration. Designed to optimize evaporator efficiency, this internally equalized expansion valve maintains precise superheat levels across varying thermal loads, preventing liquid slugging and protecting the compressor from premature failure. As a direct OEM Lennox replacement part, it ensures seamless integration with legacy R22 air conditioning units and heat pumps, restoring factory-spec refrigerant flow dynamics. The mechanical sensing bulb provides rapid response to suction line temperature fluctuations, ensuring the evaporator coil remains fully active without overfeeding. For contractors performing system repairs or retrofits, this non-adjustable TXV eliminates the guesswork of manual calibration while maintaining consistent subcooling and pressure drops required for high-performance cooling cycles. Durable brass construction and precision-machined internal orifices ensure long-term reliability in demanding residential and light commercial HVACR applications.
Key Benefits for Technicians
- Precise Refrigerant Metering: Specifically tuned for 3-ton R22 systems to ensure optimal saturation temperatures within the coil.
- Optimized System Efficiency: Maintains consistent superheat control, reducing energy consumption and operational wear on the compressor.
- Application Versatility: Compatible with various Lennox evaporator coils requiring a B10 flowrater interface.
- Robust Construction: Built to withstand high-pressure spikes and thermal cycling common in legacy R22 hardware.
Common Technical Questions
Is this TXV compatible with R410A systems?
No, the Lennox 26K49 is calibrated strictly for R22 refrigerant pressures and flow rates. Installing this on an R410A system will cause immediate metering failure and potential compressor damage.
Does this valve require an external equalizer line?
This specific model is an internally equalized TXV, meaning it senses pressure directly at the valve outlet rather than requiring a separate tap on the suction line.
Can this replace a standard fixed orifice or piston?
Yes, this expansion valve kit can be used to upgrade a fixed orifice system to improve seasonal energy efficiency, provided the coil header allows for the bolt-on or sweat-in installation of the TXV assembly.
