3 Definition of terms
Working medium
The medium that flows through the valve.

Intended area of use

The GEMÜ 653 or 654 valve is designed

for installation in piping systems. It
controls a flowing medium by manual
operation.

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.
The valve will seal in both flow directions up to full operating pressure (All pressures are gauge pressures).

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.

The valve may only be used providing

the product technical criteria are
complied with (see chapter 5
"Technical data").
Do not paint the bolts and plastic parts of

the valve!
Use the valve only for the intended
purpose!
Otherwise the manufacturer liability and

guarantee will be void.
Use the valve only in accordance with
G
the operating conditions specified in
the contract documentation and in the
installation, operating and maintenance
instructions.
The valve may only be used in
G
potentially explosive zones confirmed
in the declaration of conformity (ATEX).
