that the slings attached to the valve body
bear the entire load.

Observe lifting instructions (see sec -
tion 4.2.2).
SAMSON's After‑sales Service department
can provide more detailed transport and lift
-
ing instructions on request.

4.2.2 Lifting
To install a large valve into the pipeline, use
lifting equipment (e.g. crane or forklift) to lift
it.
Lifting instructions
− 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.
−
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 the additional sling be-
tween the lifting eyelet and rigging
equipment (hook, shackle etc.) does not
bear any load when lifting valves larger
than NPS 6. The sling only protects the
control valve from tilting while being lift-
ed. Before lifting the control valve, tight-
en the sling.
