4.3.2 Lifting the valve
Risk of personal injury and valve damage
due to incorrect lifting of the valve.
Special lifting conditions apply to valves in
Class 900 and higher as well as
≥ NPS 24.

Contact our 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 piston 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) Valves up to NPS 12 and
NPS 16 (Class 150)
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. Attach others sling to the lashing point
on the actuator and to the rigging equip-
ment.
3. Version with welding ends: secure the
slings attached to the body against slip-
ping using a connector.
4. Carefully lift the control valve. Check
whether the lifting equipment and acces-
sories can bear the weight.
5. Move the control valve at an even pace
to the site of installation.
6. Install the valve into the pipeline (see the
'Installation' section).
7. 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.
8. Remove slings.
