chemical properties of the body and diaphragm material.

The sterilization temperature is only valid for steam (saturated steam) or superheated water.
If the sterilization temperatures listed above are applied to the EPDM diaphragms for longer periods of time, the
service life of the diaphragms will be reduced. In these cases, maintenance cycles must be adapted accord-
ingly.
PTFE diaphragms can also be used as steam barriers; however, this will reduce their service life. This also ap-
plies to PTFE diaphragms exposed to high temperature fluctuations. The maintenance cycles must be adapted
accordingly. GEMÜ 555 and 505 globe valves are particularly suitable for use in the area of steam generation
and distribution. The following valve arrangement for interfaces between steam pipes and process pipes has
proven itself over time: A globe valve for shutting off steam pipes and a diaphragm valve as an interface to the
process pipes.

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.
