Introduction TUA/TUAE valves are made of stainless steel and are therefore very suitable for refrigeration systems in the food industry.

TUA/TUAE valves are available with interchangeable orifice assembly in straightway versions.

TUA/TUAE has been specially developed for soldering into hermetic refrigeration systems.

TUA/TUAE valves can be used in many different forms of refrigeration systems, for example:

Traditional refrigeration systems

Heat pump systems

Air conditioning units

Refrigeration appliances

Liquid coolers

Ice cube machines

Mobile refrigeration systems

Features Laser-welded, stainless steel thermostatic diaphragm element - optimum function - long diaphragm life - high pressure resistance

Stainless steel bulb - simple and fast installation - good heat transfer from pipe to bulb

Adjustable superheat - accurate setting - adjustable in operation

Available with MOP (Max. Operating Pressure)

Wide range of valves

Interchangeable filter for easy cleaning

Bleed orifices available on special request

Interchangeable orifice assembly designed for: - Easy mounting - Optimized tightness

Bimetal connections - Simple, fast soldering without the need for wet cloth or refrigeration pliers.

Refrigerants R22, R134a, R404A, R407C, R507, R410A and future refrigerants

Capacities from 0.6 to 16 kW (0.17 to 4.5 TR) for R22 - Large capacity range in small steps

Stable regulation

Biflow function (orifice 1 to 8)

Compact design - small dimensions and low weight

Stainless steel, solder version - high connection strength and tightness - capillary tube joints of high strength and vibration resistance

The standard range can be supplied in the following versions:Range N –40 to +10°C, without MOPRange N −40 to +10°C, MOP +15°CRange NM −40 to − 5°C, MOP 0°CRange B −60 to −25°C, without MOPRange B −60 to −25°C, MOP −20°CValves for special temperature ranges can be supplied.

Capacity

Correction factor for subcooling ∆tsub

Note:Insufficient subcooling can produce flash gas.

Correction for subcooling ∆tsub

The 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 = R22Evaporating temperature te = −10°CPressure drop in valve ∆p = 10 barSubcooling ∆tsub = 15 KEvaporator capacity = 3 kWCorrection value (table) = 1.11The corrected evaporator capacity thus becomes 3 divided by 1.11 = 2.7 kW

Design/Function

1. Bulb with capillary tube2. Thermostatic element with diaphragm3. Setting spindle for adjustment of static superheat SS4. Orifice assembly5. Filter

Fig. 5 Superheat

SuperheatSee fig. 5SS = static superheatOS = opening superheatSH = SS + OS = total superheatQnom = rated capacityQmax = maximum capacity

Static superheat SS can be adjusted with setting spindle 3, see fig. 4.

The standard superheat setting SS is 5 K for valves without MOP and 4 K for valves with MOP (except R507).The opening superheat OS is 4 K from when opening begins to where the valve gives its rated capacity Qnom..

ExampleStatic superheat SS = 5 KOpening superheat OS = 4 KTotal superheat SH = 5 + 4 = 9 K
