1 Use
1.1 Intended use
These cylinder pressure regulators are intend-
ed for use with compressed gases released
under pressure, on pressurized gas cylinders
up to 300 bar filling pressure (depending on
technical design) as well as for liquid gases,
to reduce the corresponding cylinder pressure
and to keep the desired working pressure con-
stant. The pressure regulator must only be used
for gases for which a symbol is present on the
pressure regulator (see symbols Point 3).
1.2 Unintended use
•
Pressure regulation valves must not be
used for liquids
•
Pressure regulators must not be operat-
ed in ambient temperatures below -20 °C
and above 60 °C
•
Do not use pressure regulators for ag-
gressive gases such as ethylamine, dieth-
ylamine, ammonia etc.
1.3 Directive 97/23/EC:
Pressurised equipment (PED)
AIR LIQUIDE equipment of DN
<
25 mm
(e.g. pressure regulators, valves, non return
valves
…
) satisfy to requirement of article 3§3
of 97/23/EC directive and at the state of
the art. Consequently, these equipments shall
not be CE marked as defined in article 15.
By design, these equipment may inte-
grate pressure relief valves or burst disks.
In this case, those ones shall neither be CE
marked according to paragraph 2 of annex II.
In other case, pressure relief valves and burst
disks shall be CE Marked.
2 Safety instructions
All indications labeled with this symbol
are considered as special safety instruc-
tions.
2.1
The pressure regulators conform to the
recognized state of the art, as well as the
requirements of existing standards.
•
No changes or alterations may be per-
formed without the manufacturer‘s per-
mission.
2.2
No adapters should be installed between
the cylinder valve and the cylinder pres-
sure regulator.
Improper operation, or use for purposes
other than those intended can create
hazards for the user and other persons,
as well as damage to the pressure regu-
lator.
