5 Technical data
Working medium
Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body
and diaphragm material.
Temperatures
Medium temperature -10 to 100 °C
Sterilisation temperature
( 1 )
EPDM (code 13/3A) max. 150 °C
(2)
, max. 60 min per cycle
EPDM ( code 17) max. 150 °C
(2)
, max. 180 min per cycle
PTFE (TFM) (code 52/5A) max. 150 °C
(2)
, no time limit per cycle
PTFE (TFM) (code 5E) max. 150 °C
(2)
, no time limit per cycle
FPM ( code 4/4A) not applicable
¹ The sterilisation temperature is valid for steam (saturated steam) or superheated water.
² If the sterilisation 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
accordingly. This also applies to PTFE (TFM) diaphragms exposed to high temperature fluctuations.
PTFE (TFM) diaphragms can also be used as moisture barriers; however, this will reduce their service life.
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.
