Technical leaflet Thermostatic expansion valves, type T 2 and TE 2IntroductionThermostatic expansion valves regulate theinjection of refrigerant liquid into evaporators.Injection is controlled by the refrigerant superheat.Therefore the valves are especially suitable forliquid injection in ”dry“ evaporators where thesuperheat at the evaporator outlet is proportionalto the evaporator load.FeaturesLarge temperature rangeEqually applicable to freezing, refrigerationand air conditioning applications.Interchangeable orifice assembly– easier stocking– easy capacity matching– better service.Rated capacities from 0.5 to 15.5 kW(0.15 to 4.5 TR) for R22.Can be supplied with MOP(Max. Operating Pressure)Protects the compressor motor againstexcessive evaporating pressure during normaloperation.Stainless steel bulbFast and easy to install.Good temperature transfer from pipe to bulb.Valves for special temperature ranges can besupplied.Technical dataMax. temperatureBulb, when valve is installed: 100°CBulb, element not mounted: 60°CMin. temperatureT 2 → TE 2: –60°CMax. test pressurePT = 38 barMax. working pressurePS/MWP = 34 barMOP-pointsRefrigerantRange N–40°C → +10°CRange NM–40°C → –5°CRange NL–40°C → –15°CRange B–60°C → –25°CMOP-point in evaporating temperature t e and evaporating pressure p e+15°C / +60°F 0°C / +32°F –10°C / +15°F –20°C / –4°FR22 100 psig/6.9 bar 60 psig/4.0 bar 35 psig/3.5 bar 20 psig/1.5 barR407C95 psig/6.6 barR134a 55 psig/5.0 bar 30 psig/3.1 bar 15 psig/2.1 barR404A/R507 120 psig/9.3 bar 75 psig/6.2 bar 50 psig/4.4 bar 30 psig/3.1 barSuperheatSS = static superheatOS = opening superheatSH = SS + OS = total superheatQ nom= rated capacityQ max= maximum capacityThe standard superheat setting SS is 5 K for valveswithout MOP and 4 K for valves with MOP.The opening superheat OS is 6 K from whenopening begins to where the valve gives its ratedcapacity Q nom.Static superheat SS can be adjusted with settingspindle.ExampleStatic superheatOpening superheatTotal superheatSS = 5 KOS = 6 KSH = 5 + 6 = 11 K© Danfoss A/S (AC-DSL / SKT), 12 - 2006 DKRCC.PD.AA0.A2.02 / 520H1659 3

TE valves with mm outlet have 6 mm pressure equalization.Solder adaptorThe adaptor is for use with thermostaticexpansion valves T 2 and TE 2 withflare × solder connections. When the adaptor isfitted correctly it meets the sealing requirementsof DIN 8964.The adaptor offers the following advantages:The orifice assembly can be replaced.The filter can be cleaned or replaced.When using the solder adapter, a special orificeassembly is required. Please use the followingtables to select both the appropriate adapter andorifice asembly.Only in this way can the sealing requirements ofDIN 8964 be fulfilled.Solder adaptor for filter drier (FSA) may not beused in the T 2 inlet.Flare connectionsSee previous page.Solder adaptor without orifice assembly and filterConnection ODF solderCode no.1/4 in. 068-20626 mm 068-20633/8 in. 068-206010 mm 068-2061Filter for solder adaptorDescriptionCode no.Filter excl. orifice assembly 068-0015Orifice assembly with filter forsolder adaptorOrifice no.Code no.0X 068-208900 068-209001 068-209102 068-209203 068-209304 068-209405 068-209506 068-2096For capacities see previous page.© Danfoss A/S (AC-DSL / SKT), 12 - 2006 DKRCC.PD.AA0.A2.02 / 520H1659 5
