Lennox 33F38 TXV
The Lennox 33F38 TXV is a high-performance 4-ton thermostatic expansion valve engineered for precise refrigerant metering in residential and light commercial evaporator coils. Featuring a 3/8" x 5/8" ODF (Outside Diameter Female) connection, this OEM Lennox replacement part ensures a secure, leak-resistant fit during brazing. The integrated 30-inch capillary tube provides the necessary reach for optimal sensing bulb placement on the suction line, allowing for rapid response to load changes and accurate superheat control. Designed for R-410A refrigeration systems, the 33F38 regulates flow to prevent evaporator flooding while protecting the compressor from liquid slugging. This HVAC expansion valve is a direct drop-in for specified Lennox outdoor units and indoor coils, maintaining system efficiency and seasonal energy ratings. For field technicians, the 33F38 Lennox TXV represents a reliable solution for correcting common issues like high superheat or starved coils, ensuring the balance between sensible and latent cooling remains within manufacturer specifications.
Key Benefits:- Precise Refrigerant Metering: Maintains consistent superheat between 7 to 14 degrees F to optimize heat transfer across the 4-ton evaporator coil.
- OEM Compatibility: Genuine Lennox 33F38 part eliminates the sizing and performance risks associated with universal aftermarket valves.
- Durable Construction: Built to withstand high-pressure environments typical of modern R-410A air conditioning systems.
- Extended Reach: The 30-inch capillary allows for flexible mounting of the sensing bulb in restricted cabinet spaces.
- What are the signs of a failing Lennox 33F38 TXV? Common symptoms include the AC blowing warm air, frost forming on the evaporator coil, or inconsistent suction pressures.
- Is this valve compatible with R-22? This specific model is primarily designed for high-pressure R-410A systems; always verify the refrigerant type on the unit nameplate before installation.
- Does this include the sensing bulb? Yes, the Lennox 33F38 is a complete assembly including the 30-inch capillary and the thermostatic sensing bulb.
