Shipment and on-site transport
− Make sure the slings can be removed
from the device 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 larger than NPS6. The sling only
protects the control valve from tilting
while being lifted. Before lifting the con-
trol valve, tighten the sling.
a) Version with anges
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. 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' chapter).
6. After installation in the pipeline, check
whether the anges 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.
