Danfoss 067L5859 TXV

The Danfoss 067L5859 TR6 TXV provides professional-grade refrigerant metering for high-capacity air conditioning and refrigeration systems. Engineered specifically for R-22 and R-407C refrigerants, this thermostatic expansion valve handles a nominal capacity of 5 to 6 tons (6.7 TR / 23.6 kW). The #7 orifice and balanced port design ensure stable operation and precise superheat control even under fluctuating load conditions or varying head pressures. Designed with 3/8" ODF solder inlet and outlet connections, the valve features a 31.5-inch capillary tube for flexible bulb placement. This kit includes essential hardware for a complete field installation, featuring an Aeroquip 5/8" female connector, a Chatleff 3/4" female connector, a 3/8" flare connector, a bulb strap, and insulation tape. The brass body construction is rated for a maximum working pressure of 711 psig, making it a reliable choice for commercial HVAC system maintenance and retrofits.

Key Benefits

• System Versatility: Dual compatibility with R-22 and R-407C makes it a versatile solution for aging R-22 units and modern R-407C cooling systems.
• Balanced Port Technology: Mitigates the impact of changing pressure drops across the valve, preventing hunting and ensuring consistent evaporator feeding.
• Adjustable Superheat: Allows technicians to fine-tune the static superheat (factory set at 39.25°F/4.03°C) to meet specific site requirements.
• Installation Ready: The included multi-connector kit streamlines TR6 valve replacement, reducing downtime by providing the necessary adapters for different coil configurations.
• Robust Construction: UL recognized and built with high-quality copper and brass components to withstand rigorous industrial environments.

Common Questions

Is this TXV compatible with R-410A systems?
No, the Danfoss 067L5859 is specifically calibrated for R-22 and R-407C pressures. Using this valve with R-410A will result in improper metering and potential compressor damage.

What is the benefit of the balanced port design in this 6-ton model?
The balanced port design allows the valve to remain stable during low-load conditions or when ambient temperatures fluctuate, providing better control than standard valves in systems with variable head pressures.

Does this kit include everything needed for a field retrofit?
Yes, the kit provides multiple connector types (Aeroquip, Chatleff, and flare), a bulb strap, and insulation tape to ensure the sensing bulb is properly mounted and thermalized against the suction line.
