Improper use
Only operate the valve within approved opera-
ting limits.
In the following cases it is prohibited to opera-
te the valve:
•
The valve is not used for the designated
purpose.
•
The valve is used beyond the permitted
operating limits. 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.
We do not accept any liability for damages
caused by improper use.
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 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
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 sufficient 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 equipment
as requested in “residual risks” (refer to
chapter
2
).
Protective eye glasses
to protect from escaping fluids or
exhausting compressed air
Protective gloves
Resistance to cutting
to pro-
tect from sharp edges or ridges;
resistance to acids
to protect from
hazardous fluids
Protective footwear
to protect from parts or tools falling
down

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 the rating plate and
data sheet to the operating data. The parti-
cular application must not exceed the given
limits (e.g. pressure, temperatures).
→
You must depressurize the pipe system and
de-energize the solenoid prior to perform
mounting and maintenance works.
→
Prime the valve slowly when 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. Do not operate valve during test.
!
DANGER
Hazardous electrical voltage
(>25V AC; >60V DC)
There are risks from electrical
voltage during assembly and
maintenance.
→
The electrical connection of the solenoid
must be carried out only by a qualified
electrician.
→
You may only plug the device socket in
de-energized state.
→
Disconnect the power supply off the sole-
noid prior to assembly or dismantling.
!
WARNING
Danger from pressurized
pipelines
Pressurized pipelines may burst
resulting in injuries.
→
Depressurize pipe system and block the
fluid stream prior to opening or unmoun-
ting the valve.
!
CAUTION
Risk of burns at the solenoid
Solenoid is heating up during
operation. Touching the solenoid
leads to risk of burns.
→
Leave the solenoid to cool down before
working at the valve.
Residual risks
kg
Weight of the valve
Phases:
transport, storage, assembly,
maintenance, disposal
Risk:
falling off, tipping over
Personal protection equipment
(PPE):
Protective footwear
Potentially explosive atmosphere
Risk:
danger of explosion
!
WARNING:
Use solenoids and
device sockets with Ex-protection.
