Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and
chemical properties of the body and diaphragm material.
The valve will seal in both flow directions up to full operating pressure (gauge pressure).

If the emergency power module is used (control module code A1, A2), the maximum ambient tem-
perature is reduced to 40 °C.
0 to 6 bar
All pressures are gauge pressures. Operating pressure values were determined with static operat-
ing pressure applied on one side of a closed valve. Sealing at the valve seat and atmospheric seal-
ing is ensured for the given values.
Information on operating pressures applied on both sides and for high purity media on request.

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.

MG = diaphragm size
Kv values determined acc. to DIN EN 60534, PP valve body with union end and DIN insert.
The Kv values for other product configurations (e.g. other diaphragm or body materials) may differ.
In general, all diaphragms are subject to the influences of pressure, temperature, the process and
their tightening torques. Therefore the Kv values may exceed the tolerance limits of the standard.
