7.1 Medium
Working medium:
Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and
chemical properties of the body and seal material.
Max. permissible viscos-
ity:
600 mm²/s (cSt)
Other versions for lower/higher temperatures and higher viscosities on request.
7.2 Temperature
Media temperature:
-10 — 180 °C
Ambient temperature:
-10 — 60 °C
* depending on version and/or operating parameters (see chapter Duty cycle and service life)
If the emergency power module is used (control module code A1, A2, Z1, Z2), the maximum ambi-
ent temperature is reduced to 40 °C.
Storage temperature:
10 — 40 °C
