Lennox 59W19 TXV
The Lennox 59W19 TXV is a precision-engineered 3-ton thermostatic expansion valve designed to maintain precise superheat at the evaporator coil, ensuring optimal refrigerant flow under varying load conditions. Featuring 3/8" x 1/2" ODF connections, this valve utilizes a balanced port design to compensate for pressure drops, preventing slugging and protecting the compressor. The 30-inch capillary tube provides sufficient length for flexible sensing bulb placement on the suction line, which is critical for accurate thermal feedback. This OEM Lennox expansion valve is a direct replacement for R-410A systems, engineered to withstand the high-pressure demands of modern HVACR equipment. For contractors performing a Lennox evaporator coil repair, verifying the internal check valve functionality and bulb insulation is essential to maximize SEER efficiency. Installing the 59W19 thermal expansion valve ensures consistent cooling performance and long-term system reliability in residential split systems and heat pump applications.
Key Technical Benefits- Precise Superheat Control: Maintains exact refrigerant metering to prevent liquid floodback and maximize heat transfer.
- OEM Compatibility: Specifically designed as a Lennox 59W19 replacement for seamless fitment in 3-ton evaporator coils.
- ODF Solder Connections: Features 3/8" inlet and 1/2" outlet copper connections for reliable, leak-free brazing in the field.
- R-410A Optimized: Built to handle the specific thermophysical properties and higher operating pressures of R-410A refrigerant.
- Balanced Port Construction: Negates the influence of inlet pressure variations, providing stable operation across a wide range of ambient temperatures.
What are the specific connection sizes for the 59W19?
This TXV features a 3/8" ODF inlet and a 1/2" ODF outlet, making it compatible with standard 3-ton Lennox liquid and suction line configurations.
Does this valve include the sensing bulb mounting hardware?
Yes, the Lennox 59W19 is typically supplied with the necessary clamps to ensure tight thermal contact between the sensing bulb and the suction line.
Can this TXV be used on 2.5-ton systems?
While sized for 3-ton nominal capacity, compatibility depends on the specific evaporator coil match-up and refrigerant requirements. Always verify the Lennox parts list for your specific model number.
