given limits or fixed value
1.5 Intended use
The valve is solely intended to control or stop
a fluid flow within approved operating limits.
The fluid must only flow through the valve in
the determined flow direction.
You may only operate the valve with fluids that
will not cause any chemical reaction with the
valve’s materials or lead to abrasive effects.
Under the following conditions, a valve with
nominal diameter > DN 25 is not approved as
the only shut-off valve at the end of a pressure
line:
•The contents of the pressure system must
not be released into the atmosphere.
•The contents of the pressure system must
not be transferred to a downstream system
with lower nominal pressure rating (PN).
1.6 Improper use
In the following cases it is prohibited to opera-
te the valve:
•The valve is not used for the designated
purpose.
•The permitted temperature and pressure
ranges are exceeded.
•Damages to the valve – e.g. cracks,
deformation – were detected but the valve
remains in operation.
•Malfunctions were detected but the valve
remains in operation.
•The valve has been modified without authori-
sation of the manufacturer.
•The safety instructions of this documentation
are not observed.
For damages caused by improper use, the
liability of the manufacturer is excluded.
Our guarantee expires in the following cases:
•Undue intervention and altering are done to
the valve.
•This documentation or the operating limits
as shown in the particular data sheet are not
observed.
1.7 Obligations of operator
Product
→Over the entire life cycle of the valve all
applicable regulations must be observed.
The instructions of this operation manual
must be observed and followed.
→Initiate a risk assessment of the overall
installation, to detect potential dangers that
may occur in combination of the valve with
other components.
Persons
→Initiate the instruction of each person who
is working with the valve.
Applicable regulations about occupatio-
nal safety ad safety engineering must be
known and applied.
Documentation
→This documentation must be fully read and
understood.
→The instructions given in this operation
manual must be put into practice.
→This documentation must be available at
any time.
Markings at the operating site
→Ensure adequate warning of the risks linked
to the valve. Use in the area of the installed
valve the following warning and prohibition
sings in compliance with EN ISO 7010 and
and BGV A8 (VBG125):
Warning sign to indicate risk of
burns at the solenoid
Warning sign to indicate elec-
trical hazards at the solenoid
Prohibition sign to
prevent people from entering
hazardous areas
1.8 Personnel qualification
→Ensure as operator that persons who work
on or with the valve are sufficent qualified
for this job.
→Comprehensively train the operating per-
sonnel in terms of safety.
→Only allow trained specialists to perform
electric connections, commissioning, main-
tenance and trouble shooting.
Demands
Operating personnel must be instructed on
operational sequences and procedures.
Operating personnel must know its responsi-
bilities regarding the work to be performed.
Trained specialists must possess profound
knowledge in mechanical engineering, electri-
cal engineering, hydraulic und pneumatic.
Trained specialists must be authorized to
commission, ground and designate devices,
systems and power circuits according to the
standards of safety technology.
Trained specialists must possess profound
knowledge about design and principle of ope-
ration of the valves and the plant.
1.9 Personal protection equipment
→Wear appropriate protection equipment.
Observe the personal protection equip-
ment as requested in “residual risks” (see
chapter 2 ).
Protective eye glasses
to protect from escaping fluids or
exhausting compressed air
Protective gloves
Resistance to cutting to protect
from sharp edges or ridges;
Resistance to acids to protect from
hazardous fluids
Protective footwear
to protect from parts or tools falling
down
2 General safety instructions
These safety instructions are only related to
the single valve. In combination with other
plant components there may be other potential
dangers, which must be taken into account by
carrying out a risk analysis for the system.
→Compare the details on rating plate and
datasheet to the operating data. The limits
for the particular application (e.g. pressure,
temperature) must not be exceeded.
→Only perform assembly and maintenance
works when the pipe system is in depres-
surized state.
→Flood the valve slowly during commissio-
ning. Fast pressurizing will cause the valve
to open briefly.
→Strength tests with the valve seat open are
permitted maximum up to 1.5 times of the
nominal pressure rating (PN) at room tem-
perature. The valve must not be operated
during these tests.
