Thermostatic expansion valves

Type T2 / TE2

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

y Large temperature range

– Equally applicable to freezing, refrigeration and air conditioning applications.

y Interchangeable orice assembly

– easy storage – easy capacity matching – better service. – easy cleaning and replacement of lter

y Rated capacities from 1 to 20.5 kW /

0.3 to 5.8 TR for R407C

y Can be supplied with MOP (Max. Operating

Pressure). – Protects the compressor motor against excessive evaporating pressure during normal operation

y Stainless steel bulb and Danfoss patented

bulb strap – Fast and easy to install – Good temperature transfer from pipe to bulb

y Valves for special temperature ranges can be

supplied

y Design protected

Identication The thermostatic element has laser engraved

data 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.

Orice assembly for T2 and TE2

The orice assembly is marked with the orice size (e.g. 06) and week stamp + last number in the year (e.g. 174). The orice assembly number is also given on the lid of its plastic container.

Capillary tube label for T2 and TE2

The label gives the orice size (04) and consists of the lid of the orice assembly plastic container. It can easily be fastened around the expansion valve capillary tube to clearly identify the valve size.

Design Function General

T2 and TE2 valves have an interchangeable orice assembly.

The orice assembly is suitable for all versions of valve body and refrigerants and in all evaporating temperature ranges. The charge in the thermostatic element depends on the refrigerant and evaporating temperature range. The valves are available with internal (T2) or external (TE2) pressure equalization.

External pressure equalization should always be used on systems with liquid distributors. The bulb gives fast and precise reaction to temperature changes in the evaporator. The bulb is xed with a Danfoss patented bulb strap for quick, easy and reliable connection. The valves are able to withstand the e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.

For ﬂare connection 068-0003

For solder adaptor 068-0015

The adaptor is for use with thermostatic expansion valves T2 and TE2. When the adaptor is ﬁtted correctly it meets the sealing requirements of DIN 8964. The ﬂare oriﬁce in T2 and TE2 can be used with a solder adaptor when the oriﬁce ﬁlter

is replaced with a speciﬁc ﬁlter intended for solder adaptors. Only in this way the sealing requirements of DIN 8964 can be fulﬁlled. Solder adaptors for ﬁlter driers (FSA) must not be used on the T2 inlet.
