Danfoss 067L5957 Expansion Valve

The Danfoss 067L5957 is a contractor-grade TR6 expansion valve kit engineered specifically for high-efficiency R410A refrigeration and air conditioning systems. This 5-ton thermostatic expansion valve features a robust stainless steel sensing bulb and power element, ensuring survival in corrosive environments while maintaining precise superheat regulation. Designed for versatile field replacement, the kit includes a straight-body TXV with 3/8" ODF sweat connections and is compatible with Aeroquip and Chatleff adapters to match most evaporator coil configurations. The externally equalized design, featuring a 24-inch equalization line and an adjustable superheat spindle, allows for fine-tuning based on specific load requirements, effectively preventing liquid slugging and compressor damage. An integrated internal check valve makes this unit fully compatible with heat pump applications, providing reliable bi-directional control. Whether you are performing a piston-to-TXV conversion or replacing an OEM part, this universal kit provides the balance port technology needed for stable operation across a wide range of ambient temperatures.

• Universal Compatibility: Includes adaptors for Aeroquip and Chatleff fittings, making it a drop-in replacement for most 5-ton R410A evaporator coils.
• Precision Control: The adjustable superheat spindle and externally equalized port allow for exact refrigerant metering to maximize system SEER.
• Heat Pump Ready: Features a built-in check valve that facilitates seamless operation in both cooling and heating modes.
• Corrosion Resistance: High-grade stainless steel capillary tube and sensing bulb prevent premature failure from moisture or oxidation.
• Balanced Port Design: Maintains consistent refrigerant flow even during significant head pressure fluctuations.

Can this valve be used on systems smaller than 5 tons?
The Danfoss 067L5957 is specifically rated for 4.5 to 5-ton capacities. Using this on significantly smaller systems can lead to hunting and unstable superheat control. Always verify the tonnage of the evaporator coil before installation.

Does this kit include the mounting hardware?
Yes, the kit comes complete with a copper bulb strap, 35-inch insulating foam tape, and the necessary evaporator fittings for a professional installation.

Is this TXV compatible with older R22 systems?
No, this model is designed strictly for R410A refrigeration systems. Nitrogen-charged elements are calibrated specifically for the pressure-temperature curve of R410A.
