Danfoss 068U4101 TCAE Thermostatic Expansion Valve Orifice Assembly No. 2

The Danfoss 068U4101 is a No. 2 Orifice Assembly designed as a genuine replacement part for Danfoss TCAE series thermostatic expansion valves (TXVs). Part of the Danfoss TCA Parts Program, this orifice assembly allows technicians to service and restore TCAE valves to original performance without replacing the entire valve body, reducing downtime and parts cost in commercial refrigeration and HVAC systems.

The orifice precisely meters refrigerant flow into the evaporator, directly controlling system capacity and superheat. Orifice No. 2 is sized for medium-capacity TCAE valve applications and is compatible with a wide range of common refrigerants including R-22, R-407C, R-404A, R-507A, R-410A, R-134a, R-513A, R-448A, R-449A, R-450A, R-452A, R-454C, and R-23, making it suitable for a broad spectrum of refrigeration and air conditioning systems.
