Danfoss TZ2 068Z3496 pressure regulator

MAKING MODERN LIVING POSSIBLE Data sheet Thermostatic expansion valves Type T2 / TE2 Thermostatic expansion valves regulate the injection of refrigerant liquid into evaporators. Injection is controlled by the refrigerant superheat. Therefore the valves are especially suitable for liquid injection in ”dry“ evaporators where the superheat at the evaporator outlet is proportional to the evaporator load. Features Large temperature range Can be supplied with MOP Equally applicable to freezing, refrigeration (Max. Operating Pressure) and air conditioning applications. Protects the compressor motor against Interchangeable orifice assembly excessive evaporating pressure during normal – easy storage operation. – easy capacity matching Stainless steel bulb and Danfoss patented bulb – better service. strap Rated capacities from 0.96 to 20.5 kW Fast and easy to install. (0.27 to 5.82 TR) for R407C. Good temperature transfer from pipe to bulb. Valves for special temperature ranges can be supplied.

This engraving gives valve type (with code number), evaporating temperature range, MOP point, refrigerant, and max. working pressure. PS/MWP. The code refers to the refrigerant for which the valve is designed: X = R22/R407C1) Z = R407C N =  R134a S =  R404A/ R507 Production place and date N4511A = N = Nordborg, Denmark (BE = Wuqing, China) 45 = week 11 = 2011 A = Monday 1 ) For R407C plants, please select valves from the dedicated R407C program Orifice assembly for T 2 and TE 2 Orifice assembly and filter for flare x flare version The orifice assembly is marked with the orifice for T 2 and TE 2 size (e.g. 06) and week stamp + last number in the year (e.g. 174). The orifice assembly number is also given on the lid of its plastic container. Capillary tube label for T 2 and TE 2 Capillary tube label T 2 and TE 2 The label gives the orifice size (04) and consists of the lid of the orifice assembly plastic container. It can easily be fastened around the expansion valve capillary tube to clearly identify the valve size.
