The adaptor is for use with thermostatic expansion valves T 2 and TE 2 with fl are × sol der connections. When the adaptor is fi tted correctly it meets the sealing requirements of DIN 8964.

The adaptor off ers the following advantages:

The orifi ce assembly can be replaced.

The fi lter can be cleaned or replaced.

When using the sol der adapter, a special orifi ce assembly is required. Please use the following tables to select both the appropriate adapter and orifi ce asembly.Only in this way can the sealing requirements of DIN 8964 be ful fi l led.Solder adaptor for fi lter drier (FSA) may not be used in the T 2 inlet.

Correction for subcooling Δt

sub

The evaporator capacities used must be corrected if subcooling deviates from 4 K.The corrected capacity can be obtained by

dividing the required evaporator capacity by the correction factor below. Selections can then be made from the tables above.

Note: Insuffi cient subcooling can producefl ash gas.

ExampleRefrigerant = R22Evaporator capacity Q

e = 5 kW

Subcooling = 10 K

DesignFunction

GeneralT 2 and TE 2 valves have an interchangeable orifi ce assembly.

For the same valve type and refrigerant, the associated orifi ce assembly is suitable for all vers ions of valve body and in all evaporating tem pe ra tu re ranges. The charge in the thermostatic element depends on the evaporating temperature range.The valves can be equipped with internal (T 2) or external (TE 2) 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 fi tting the bulb quick and easy.The valves are able to withstand the eff ects 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.

Identifi cation The thermostatic element is fi tted with a laser engraving on top of the diaphragm.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 Z = R407CN = R134a S = R404A/ R507

Orifi ce assembly for T 2 and TE 2The orifi ce assembly is marked with the orifi ce size (e.g. 06) and week stamp + last number in the year (e.g. 174). The orifi ce assembly number is also given on the lid of its plastic container.

Capillary tube label for T 2 and TE 2The label gives the orifi ce size (04) and consists of the lid of the orifi ce assembly plastic con tai ner. It can easily be fastened around the expansion valve capillary tube to clearly identify the valve size.
