Data sheetThermostatic expansion valve Type TUB/TUBE and TUC/TUCEIntroductionThe TU series of thermostatic expansion valves has been developed for soldering into hermetic refrigeration systems.TU valves are made of stainless steel and are therefore very suitable for use in the food industry.TU valves can be used in many forms of refrigeration systems, in particular:-Traditional refrigeration systems -Heat pump systems -Air conditioning units -Refrigeration appliances -Liquid coolers-Ice cube machines-Mobile refrigeration systemsAll variants are available in both single packs and industrial packs as required by the customer.TUB/TUBE have adjustable superheat and are available in angleway versions as standard.TUC/TUCE have fixed superheat, but are otherwise identical to TUB.TUB/TUBE and TUC/TUCE can be delivered in straightway versions.All straightway versions and TUC valves are produced to order and therefore this catalogue contains no description of a standard range or code numbers.TU valves are also available in a number of variants that give countless combination possibilities.Contact Danfoss for further information.Features·Bimetal connections-straightforward and fast soldering (no wet cloth or refrigeration pliers required).·RefrigerantsR 22, R 134a, R 404A, R 507, R 407C,R 410A and future refrigerants·Capacities from 0.6 to 16 kW (0.17 to 4.5 TR)for R 22-large capacity range in small steps ·Stable regulation·Biflow function (orifice 0 to 8)·Compact design- small dimensions and low weight ·Stainless steel, hermetically tight solder version-high connection strength -high corrosion resistance-capillary tube joints of high strength and vibration resistance·Laser-welded, stainless steel thermostatic diaphragm element -optimum function -long diaphragm life-high pressure resistance·Stainless steel double contact bulb -straightforward and fast installation -good heat transfer from bulb to pipe ·Adjustable superheat type (TUB/TUBE)-accurate setting-adjustable in operation·Fixed superheat type (TUC/TUCE)·Filter with high dirt retention capacity ·Available with self-cleaning bleed·Available with MOP (Max.

KTUTUTUNote:Insufficient subcooling can produce flash gas.Correction for subcooling D t subThe evaporator capacity used must be corrected if subcooling deviates from 4 K.The corrected capacity can be obtained by dividing the evaporator capacity by the correction factor given below.Since the expansion valve capacity must be equal to or slightly more than the corrected evaporator capacity of 2.7 kW, a TUB/TUBE with orifice 5 and a table capacity of 2.8 kW would be a suitable choice.Refrigerant = R 22Evaporating temperature t e = -10°C Pressure drop in valve D p = 10 bar Subcooling D t sub = 15 K Evaporator capacity = 3 kW Correction value (table) = 1.11The corrected evaporator capacity thus becomes 3 divided by 1.11 = 2.7 kWSelection exampleData sheet Thermostatic expansion valve, type
