Danfoss 067L5856 TXV

The Danfoss 067L5856 is a professional-grade TR6 Thermostatic Expansion Valve designed for high-performance refrigerant metering in residential and light commercial systems. Engineered for versatility, this 4.5 Ton TXV features an external equalizer and an internal check valve, making it a reliable solution for both standard air conditioning and reverse-cycle heat pump applications. The balanced port design mitigates the impact of fluctuating condensing pressures, ensuring stable superheat control across a wide operating range.

Constructed with a durable brass body and laser-welded stainless steel power element, the 067L5856 provides superior resistance to diaphragm fatigue. This model utilizes 3/8" ODF solder connections and is optimized for R22 and R407C refrigerants, though it is often cross-referenced in universal kits for R410A retrofits. Technicians can rely on the adjustable superheat spindle to fine-tune system efficiency, while the anti-hunt bulb charge prevents evaporator flooding during rapid load changes.

• Universal Compatibility: Integrated check valve allows for seamless operation in both AC and heat pumps without external bypass piping.
• Durable Construction: Laser-welded diaphragm and brass body offer enhanced reliability under high-pressure conditions (up to 711 psig).
• Precise Metering: Balanced port design maintain consistent superheat even during varying ambient temperatures.
• Field-Adjustable: Features a manual adjustment spindle to optimize superheat settings for specific system requirements.
• Complete Kit: Includes bulb strap and insulating tape to ensure proper thermal contact and accurate sensing.

Can the Danfoss 067L5856 be used with R410A?
While originally specified for R22 and R407C, this TR6 series valve is frequently used in universal applications; however, internal orifice sizing and spring rates are optimized for R22/R407C pressures. Verify system tonnage and pressure drop requirements before substituting.

What is the purpose of the external equalizer on this model?
The 1/4" flare external equalizer compensates for pressure drops across the evaporator coil, ensuring the valve maintains the correct superheat based on actual pressure at the coil outlet rather than the valve outlet.

Is this valve suitable for heat pump systems?
Yes. The built-in internal check valve allows refrigerant to bypass the metering orifice during the heating cycle, eliminating the need for a separate external check valve.
