Work on the valve
Work relating to the installation, commissioning,
maintenance and repair of the valve may only be
carried out by qualified persons. Qualified persons
are defined as persons who, on the basis of edu-
cation, experience and instruction, have sufficient
knowledge of applicable requirements and ac-
cepted rules of the technology.
Throughout any installation, commissioning, main-
tenance and repair work, it is the responsibility of
the operator to ensure that there is no risk of ex-
plosion.
Before starting such work, the operator has to
ensure that tools and equipment are only used if
they do not damage the valve and they do not
leave behind residues that are inflammable.
In addition, clean the valve before starting such work,
in particular removing dust, liquids and other depo-
sits. Cleaning should be done using a lint-free cloth.
Tools may not be used if they might cause a static
charge on use.
2. Safety instructions
Read the operating instructions thoroughly before
installation, commissioning, maintenance, repair and
storage, and observe them. Failure to observe the
operating instructions may result in damage to the
valve or the parts of the system connected to it.
In particular, in the case of explosive atmospheres,
any failure to observe the operating instructions
may result in an explosion.
The system operator must make these operating
instructions visible and easily accessible to opera-
ting and maintenance personnel.
Compliance with applicable standards/legal requi-
rements must be enforced. This particularly applies
to plant safety and environmental protection.
A list of such standards, etc. appears in the annex
by way of example.
Before starting commissioning, installation, main-
tenance and repair work, the hydraulic system must
be depressurised and power must be disconnected
from the electrical installation.
In addition, the electrical installation must be secured
so that power cannot be restored unexpectedly.
The valve may become hot during operation. To
avoid risk of burns, do not touch the valve surface.
The system operator must monitor the temperature
and cool the oil if necessary in order to the keep
within the maximum temperatures set out in these
operating instructions (see technical data). In this
connection, observe the relevant directions in the
operating instructions of the supplier (solenoid
system).
Any leaks occurring at the valve must be rectified
immediately.
