Danfoss 067L5955 Expansion Valve

The Danfoss 067L5955 (Type TR 6) is a high-performance R410A thermostatic expansion valve engineered for precision refrigerant metering in 3-ton residential and light commercial systems. Designed with a balanced port construction, this valve compensates for varying condensing pressures, making it an ideal choice for heat pump applications and systems requiring stable superheat control across a wide range of operating conditions. This kit includes essential TXV replacement parts, featuring 3/8" ODF inlet and 1/2" ODF outlet connections, and is supplied with both Aeroquip and Chatleff fittings to ensure seamless integration with various evaporator coil configurations.

Constructed with a forged brass body and a laser-welded stainless steel power element, the 067L5955 offers superior durability and resistance to vibration-induced fatigue. The 30-inch stainless steel capillary tube provides the flexibility needed for clean routing in tight cabinets, while the externally equalized design with a 1/4" ODF flare nut ensures accurate pressure sensing at the evaporator outlet. With a Maximum Operating Pressure (MOP) of 660 PSI and an anti-hunt bulb charge, this valve prevents compressor slugging and maintains system efficiency even during rapid load shifts.

• Universal Field Replacement: Includes Aeroquip and Chatleff female fittings for maximum compatibility with diverse OEM evaporator coils.
• Optimized for Heat Pumps: Features an internal check valve and balanced port design to facilitate bi-flow operation and stable performance in seasonal transitions.
• Enhanced Durability: The stainless steel bulb and capillary tube resist corrosion and mechanical stress better than traditional copper components.
• Precision Metering: Equipped with a number 3 orifice and adjustable superheat spindle to fine-tune system performance post-installation.
• High Pressure Rating: Robust 660 PSI MOP rating specifically calibrated for high-pressure R410A refrigerant systems.

Is the Danfoss 067L5955 compatible with R22 systems?
No, this specific model is optimized and charged specifically for R410A refrigeration cycles. Using it with R22 will result in incorrect superheat and potential system damage.

Does this valve support bi-flow operation for heat pumps?
Yes, the TR 6 series includes an internal check valve and balanced port design, making it suitable for both cooling-only and heat pump applications.

How do I install the bulb for the best thermal transfer?
The kit includes a specialized bulb strap and insulation tape. Always mount the bulb on a horizontal suction line at the 4 or 8 o’clock position and ensure it is fully insulated from ambient air.
