Danfoss 068U2164 Expansion Valve

The Danfoss 068U2164 is a T2 series thermostatic expansion valve designed for precise superheat control in light commercial refrigeration and air conditioning systems. Engineered for R22 refrigerant, this TXV with internal equalization features a 3/8" flare inlet and a 1/2" flare outlet, utilizing an 06 orifice size for consistent flow regulation. The stainless steel power element provides increased durability against corrosion and vibration, while the laser-welded diaphragm ensures a stable superheat setting over the life of the valve. For technicians performing retrofits or repairs, this replaceable orifice expansion valve offers field flexibility by allowing capacity adjustments without removing the entire valve body. The brass body construction and high-grade bellows assembly are built to withstand the rigorous pressure fluctuations typical in HVACR evaporator coils, maintaining system efficiency and protecting the compressor from liquid slugging during varied load conditions.

• Interchangeable orifice assembly allows for easy capacity matching and simplified field service.
• Stainless steel power element resists harsh environments and extends component longevity.
• Internal equalization simplifies installation by eliminating the need for an external balance line on standard evaporator circuits.
• Laser-welded diaphragm construction provides precise superheat regulation and minimizes the risk of refrigerant leaks.
• Designed for R22 compatibility, making it a reliable direct replacement for aging service applications.

What is the connection type for the Danfoss 068U2164?
