Danfoss 068Z3384 TN 2 R134a Expansion Valve (Int. Eq. - Solder) MOP N

The Danfoss 068Z3384 TN 2 R134a Thermostatic Expansion Valve is an expansion valve with an interchangeable orifice that precisely meters the liquid refrigerant in the refrigeration circuit according to the evaporator load. With its brass body, stainless steel sensing element and diaphragm head, it ensures stable and efficient operation in commercial and industrial refrigeration systems.

Efficient Refrigeration Performance with Balanced Flow Control

Thanks to its interchangeable orifice, the TN 2 body type easily adapts to different capacities with the same valve body and simplifies maintenance/service. The independent thermostatic sensing element detects the superheat at the evaporator outlet and continuously adjusts the refrigerant flow rate; this protects the compressor against liquid slugging, keeps the evaporator surface optimally filled and increases energy efficiency. With its charge suitable for R134a refrigerant systems, it is used reliably in cold rooms, supermarket display cabinets, air conditioning and process cooling applications.
