Danfoss 068Z3428 TES 2 R404A (Ext. Eq.-Solder) MOP B Thermostatic Expansion Valve

Precisely regulating the liquid mass flow in refrigeration systems, the Danfoss 068Z3428 TES 2 R404A (Ext. Eq.-Solder) MOP B thermostatic expansion valve is designed for commercial and industrial refrigeration applications operating with R404A refrigerant. Thanks to its external equalizer design and MOP pressure limiting feature, it keeps evaporator superheat stable, providing an efficient and safe refrigeration cycle.

Stable Superheat and MOP Pressure Protection

TES 2 series expansion valves continuously adjust the amount of refrigerant entering the evaporator under variable load conditions by means of the sensor and diaphragm mechanism. The MOP (Maximum Operating Pressure) charge characteristic prevents compressor overload and limits suction pressure, particularly in cold rooms and at start-up. The external equalizer connection provides accurate superheat control even in evaporators with a high pressure drop.
