Identication
Element label
Orice assembly marking
for TE 5 – TE 55
The thermostatic element is tted with a label (on
top of the diaphragm).
The label holds information like valve type,
evaporating temperature range, MOP point,
refrigerant, max. working pressure PS / MWP and
production date.
Production place and date (BE1315B) mean:
BE = Wuqing, China
13 = Week
15 = Year 2015
B = Tuesday
Orice assembly for TE 5 – TE 55
The orice assembly is marked on top of the
spring cup, e.g. as shown in the gure.
TE 12 = For valve type
06 = Orice no.
067B2709 = Orice code no. for sales order
1315 = week 13, year 2015
Capillary tube tag for TE 5 – TE 55
The label gives the orice size (06). A new label
always accompanies a new orice assembly.

Max. temperature
Bulb, when valve is assembled:100 °C / 210 °F.
Complete valve when not assembled: 70 °C / 160 °F.
Min. temperature: -60 °C / -75 °F.
SS = static superheat
OS = opening superheat
SH = SS + OS = total superheat
Q
nom
= rated capacity
Q
max
= maximum capacity
SS can be adjusted with setting spindle.
The standard factory SS setting is 4 K / 7.2 °F.
The OS is 4 K / 7.2 °F from when opening begins to
where the valve reaches its rated capacity Q
nom
.
OS is determined by the design and cannot be
changed.
Superheat
Example
Static superheat SS = 4 K / 7.2 °F
Opening superheat OS = 4 K / 7.2 °F
Total superheat SH = 4 + 4 = 8 K
SH = 7.2 + 7.2 = 14.4 °F
Using orice with range B element, please check
superheat under running conditions and
readjust SS setting, if necessary.
Max. test pressure: 32 bar / 465 psig.
Maximum working pressure: 28 bar / 400 psig.
