Danfoss 067L5956 Expansion Valve

The Danfoss 067L5956 is a professional-grade TR6 Thermostatic Expansion Valve (TXV) designed for precise refrigerant metering in 4-ton R-410A systems. This universal aftermarket kit is a staple for technicians needing a reliable solution for both residential and commercial HVAC split systems and heat pumps. Engineered with a built-in check valve, it allows for bi-flow operation, eliminating the need for external bypass piping during heat pump cycle reversals. The 067L5956 features a 3/8" ODF inlet and 3/8" ODF outlet solder connection, providing a secure, leak-proof fit in the liquid line. Its externally equalized design uses a 1/4" flare connection to ensure accurate superheat control across varying evaporator loads. With a 31.5-inch capillary tube and a durable stainless steel sensing bulb, this valve maintains optimal system efficiency and prevents liquid slugging, even under high-head pressure conditions up to a 711 psig maximum working pressure.

• Universal Compatibility: Includes Aeroquip and Chatleff adapters to fit most major OEM evaporator coil configurations.
• Optimized Performance: Features an adjustable superheat spindle to fine-tune system subcooling and evaporator saturation.
• Enhanced Durability: Constructed with a brass body and stainless steel power element to resist corrosion and vibration fatigue.
• Installation Ready: The complete TXV kit includes the valve, bulb strap, insulation tape, and necessary fittings for a fast field replacement.
• High Pressure Rating: Rated for a MWP of 711 psig, making it fully compliant with high-pressure R-410A refrigeration cycles.

Is the Danfoss 067L5956 compatible with heat pump systems?
Yes. Because it features an integrated check valve, it handles reverse flow during the heating cycle without requiring additional external components, simplifying the piping layout.

Does this valve come with the orifice included?
Yes, this specific model uses a No. 4 orifice, which is sized for 4-ton (48,000 BTU) cooling capacities when used with R-410A refrigerant.

Can I use this TXV to replace a fixed orifice or piston?
In most cases, yes. Upgrading to a TR6 expansion valve improves seasonal energy efficiency and provides better protection for the compressor compared to fixed metering devices.
