Lennox 14K64 TXV
The Lennox 14K64 is a heavy-duty, 11-ton thermostatic expansion valve (TXV) engineered specifically for high-capacity R22 refrigerant systems. Designed for industrial and large-scale commercial cooling applications, this thermal expansion valve features 5/8" x 1 1/8" ODF sweat connections to ensure leak-free integration with various air handler and condenser configurations. As an essential HVAC replacement part, this metering device accurately modulates refrigerant flow based on heat load, maintaining precise evaporator superheat to prevent liquid slugging and protect the compressor from damage.
For contractors servicing older R22 HVAC systems, the 14K64 offers a direct OEM solution for restoring energy efficiency and cooling performance. This valve is built with a durable brass body and a stainless steel sensing bulb to withstand high-pressure environments and provide consistent refrigerant control. Whether you are performing a TXV valve replacement or overhauling an 11-ton split system, this component ensures stable operation across varying ambient temperatures, maximizing the capacity of the indoor coil.
Key Benefits
- Precise Refrigerant Metering: Specifically calibrated for R22 refrigerant to maintain optimal superheat and improve system efficiency.
- High-Capacity Performance: Optimized for 11-ton cooling loads, making it ideal for heavy commercial Lennox cooling units.
- Durable Construction: Features robust ODF sweat connections (5/8" inlet, 1-1/8" outlet) for secure, permanent brazing into the liquid line.
- Compressor Protection: Actively prevents liquid refrigerant from entering the suction line, extending the service life of the system's most expensive components.
- OEM Compatibility: A direct Lennox 14K64 replacement designed to meet or exceed original equipment technical specifications.
Common Questions
Can I use the Lennox 14K64 in an R410A system?
No. This valve is specifically charged and calibrated for R22 pressure-temperature characteristics. Using it with R410A will result in incorrect metering and potential system failure.
What is the best way to prevent damage to the valve during installation?
Always wrap the valve body in a wet rag or use a heat-sink paste during the brazing process to protect the internal diaphragm and seals from excess heat.
Does this valve include the sensing bulb and capillary tube?
Yes, the 14K64 is a complete thermal expansion assembly including the power head, capillary tube, and sensing bulb required for proper superheat regulation.
