4.3.2 Lifting the valve
To install a large valve into the pipeline, use
lifting equipment (e.g. crane or forklift) to lift
it.
Lifting instructions
− Use a hook with safety latch (see
Fig.4-1)tosecuretheslingsfromslip-
ping off the hook during lifting and
transporting.
− Secure slings against slipping.
− Make sure the slings can be removed
from the valve once it has been installed
into the pipeline.
− Prevent the control valve from tilting or
tipping over.
− Do not leave loads suspended when in-
terrupting work for longer periods of
time.
− Make sure that the axis of the pipeline is
alwayshorizontalduringliftingandthe
axis of the plug stem is always vertical.
− Make sure that only the slings attached
to the valve body bear the load. Other
slings only protect the control valve from
tilting while being lifted. They must not
bear any load. Before lifting the control
valve, tighten the sling.
Lifting the control valve
1. Attachoneslingtoeachangeofthe
body and to the rigging equipment (e.g.
hook) of the crane or forklift (see
Fig.4-1).
2. If necessary, attach further slings to the
control valve and rigging equipment to
secure the position of the control valve
and prevent it from tilting while it is be-
ing lifted.
3. Carefullyliftthecontrolvalve.Check
whether the lifting equipment and acces-
sories can bear the weight.
4. Move the control valve at an even pace
to the site of installation.
5. Install the valve into the pipeline (see the
'Installation' section).
