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 the additional sling be -
tween the lashing point on the actuator
and rigging equipment (hook, shackle
etc.) does not bear any load when lifting
valves with an actuator that has a lifting
eyelet/eyebolt on it. The sling only pro-
tects the control valve from tilting while
being lifted. Before lifting the control
valve, tighten the sling.
a) Version with flanges
1. Attach one sling to each flange of the
body and to the rigging equipment (e.g.
hook) of the crane or forklift (see
Fig. 4-1).
2. NPS 6 and larger: attach another sling
to the lashing point on the actuator and
to the rigging equipment.
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. After installation in the pipeline, check
whether the flanges are bolted tight and
the valve in the pipeline holds.
7. Remove slings.
b) Version with welding ends
1. Attach one sling to each welding end of
the body and to the rigging equipment
(e.g. hook) of the crane or forklift (see
Fig. 4-1).
2. Secure the slings attached to the body
against slipping using a connector.
3. NPS 6 and larger: attach another sling
to the lashing point on the actuator and
to the rigging equipment.
4. Carefully lift the control valve. Check
whether the lifting equipment and acces -
sories can bear the weight.
