Industrial Valves
Check whether the valve was damaged during transport or
handling. Damage must be notified within 14 days of arrival.
The transport instructions on the packaging (e.g. wooden box)
must be followed. It must be ensured through suitable and ap-
proved sling materials and slings that no damage can occur to
connector surfaces, as well as preventing other adverse effects
on the device (e.g. actuator accessories, pipeline, sealing ele-
ments). The device may not be lifted up directly on the actuator.
A sling should be attached for larger valves.
(Examples are shown in
Fig. 1
and
Fig. 2
)
Ensure storage in the original package in an enclosed area.
This is to be done in a clean and dry environment in compliance
with the permissible ambient temperatures for the valves.
Do not lay the valve directly on the floor. Suitable supports
(e.g. delivery packaging) should be used to protect the device
against particles/dirt during storage and installation.
Protective enclosure and packaging should be removed im-
mediately before installation of the valve. This applies particu-
larly to special packaging (e.g. for specially cleaned valves).

Installation
ATTENTION: DANGER! Spring-acting
actuators
may only be
pressurised in assembled condition in the pipeline, and not
for the purposes of performance of work on the valve outside
the pipeline. There is a risk of fatal injury if the auxiliary ener-
gy suddenly fails and the valve disc then moves on its own
into the fail-safe position as a result of spring decompression.
For devices equipped with a spring return actuator with safety
position “Open” (Fail open), the valve disc may possibly need
to be closed for installation in a pipeline. It must be ensured
here that the full control pressure for closing the valve is main-
tained for the duration of the installation work. Otherwise, the
valve must be installed in the open position, e.g. by disman-
tling the pipeline.
1. For installation, it must be ensured that:
Sufficient installation space is available
The pipeline connectors are well aligned
Suitable installation tools and lifting attachments are
used
Precautions for the prevention of contact with danger-
ous fluids have been taken.
2. Furthermore, it must be ensured that:
Employees or third parties are not at risk. If applicable,
legal regulations of the country of destination must ad-
ditionally be observed
It is accessible for necessary inspection, and can be
observed from all sides, if necessary
The operation of all components is possible from a safe
position
The name-plate is recognisable.
3. The device is to be connected to the appropriately design
nated supports/connectors. It must be protected against
external mechanical influences to the extent that damage is
not expected on the device. The preferred flow direction
must be observed during installation. It points from the shaft
axis in the direction of the sealing seat and is marked by
arrows at the sides of the valve body.
