7.1 Medium
Working medium: Without UL approval
Inert gaseous and liquid media which have no negative impact on the physical and chemical prop-
erties of the body and seal material.
With UL approval
Air, water and noble gases
The following applies to both versions:
With control function 1 (normally closed (NC)), a distinction must be made between gaseous and li-
quid media.

All pressures are gauge pressures.
The permissible operating pressure depends on the working medium temperature.
Data for extended temperature ranges on request. Please note that the ambient temperature and media temper-
ature generate a combined temperature at the valve body which must not exceed the above values.
