Contact SAMSON's After-sales Service.
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.
Lifting the control valve
1. Attach one sling (or other suitable lifting
tackle) to each flange or welding end of
the valve body and to the rigging equip-
ment (e.g. hook) of the crane or forklift
(see Fig. 4-1).
2. Version with welding ends or weld -
ing-neck ends: secure the slings (or other
suitable lifting tackle) attached to the
valve body against slipping using a con-
nector.
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).
6. Version with flanges: check whether the
flanges are bolted tight and the valve in
the pipeline holds.
Version with welding ends: check
whether the weld seams hold and wheth-
er the valve in the pipeline holds.
7. Remove the slings.
