3 Definition of terms
Working medium
The medium that flows through the
diaphragm valve.
4 Intended area of use
The GEMÜ 653 or 654 diaphragm valve
is designed for installation in piping
systems. It controls a flowing medium by
manual operation.
The valve may only be used providing
the product technical criteria are
complied with (see chapter 6
"Technical data").
Do not paint the bolts and plastic parts of
the diaphragm valve!
WARNING
Use the diaphragm valve only for the
intended purpose!
® Otherwise the manufacturer liability and
guarantee will be void.
G Use the diaphragm valve only in
accordance with the operating
conditions specified in the contract
documentation and in the installation,
operating and maintenance
instructions.
G The diaphragm valve may only be used
in potentially explosive zones confirmed
in the declaration of conformity (ATEX).
5 Condition as supplied
to customer
The GEMÜ diaphragm valve is supplied as a
separately packed component.

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.
Operating temperature max. 150 °C
(dependent on medium wetted materials)
The valve will seal in both flow directions up to full operating
pressure (all pressures are gauge pressures).

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.
Version with PTFE diaphragm up to 10 bar possible with bonnet
special function "H" and forged valve body.
