3 Introduction 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: 6 F to +0 F Equally applicable to freezing, refrigeration and air conditioning plant. Interchangeable orifice assembly easier stocking easy capacity matching better service. Stainless steel power element, capillary tube and bulb high corrosion resistance high strength and vibration resistance fast installation: self-aligning bulb good thermal contact and transmission Rated capacities from to 00 TR for R22 Can be supplied with MOP (Max. Operating Pressure) Protects the compressor motor against excessive evaporating pressure. Patented double contact bulb Fast and easy to install. Good temperature transfer from pipe to bulb.

15 Design/Function General and valves have an interchangeable orifice assembly. and valves are built up of three interchangeable main components: I. Thermostatic element, II. Orifice assembly, 2 III. Valve body with connections, 3 For the same valve type and refrigerant, the associated orifice assembly is suitable for all versions of valve body and in all evaporating temperature ranges. The charge in the thermostatic element depends on the evaporating temperature range. The valves are equipped with external pressure equalization. External pressure equalization should always be used on systems with liquid distributors. The double contact bulb gives fast and precise reaction to temperature changes in the evaporator. It also makes fitting the bulb quick and easy. The valves are able to withstand the effects that normally occur with hot gas defrosting. To ensure long operating life, the valve cone and seat are made of a special alloy with particularly good wear qualities. TE 2 / TE 20. Thermostatic element (diaphragm) 2.

16 Identification The thermostatic element is fitted with a label (on top of the diaphragm).the code refers to the refrigerant for which the valve is designed: X = R22 N = R34a S = R4A/R0 Z = R40C The label gives valve type, evaporating temperature range, MOP point, refrigerant, and max. test pressure, PS. With TE 20 and the rated capacity is stamped on a band label fastened to the valve Element label Orifice assembly for, TE 2, 20 and The orifice assembly is marked on top of the spring cup, e.g. as shown in the figure. For a given size of valve, the same orifice assembly can be used for valves with ranges N and B. The thermostatic elements are different however: On and TE 2 the upper stamp (TE 2) indicates for which valve type the orifice can be used. The lower stamp () is the orifice size. On TE 20 and the upper stamp (N/B 0/3 TR) indicates the rated capacity in the two evaporating temperature ranges N and B, and the refrigerant. (0/3 TR = kw in range N and 23 kw in range B). The lower stamp (TEX ) refers to the valve type for which the assembly can be used. Orifice assembly marking for and TE 2 Orifice assembly marking for TE 20 and Capillary tube label for to The label gives the orifice size (). A new label always accompanies a new orifice assembly.
