Kv values determined acc. to DIN EN 60534, inlet pressure 5 bar, p 1 bar, PVC-U valve body and soft elastomer diaphragm.
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.

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.

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 diaphragms exposed to high temperature fluctuations.
PTFE 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.
