All pressures are gauge pressures. Operating pressure values were determined with static operating pressure
applied on one side of a closed valve. Sealing at the valve seat and atmospheric sealing is ensured for the given
values.
Information on operating pressures applied on both sides and for high purity media on request.

The pressure rating (PN) depends on the connection code.
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.
