4.2.1 Transporting
The control valve can be transported using
lifting equipment (e.g. crane or forklift).
Î
Leave the control valve in its transport
container or on the pallet to transport it.
Î
Observe the transport instructions.
Transport instructions
−
Protect the control valve against external
influences (e.g. impact).
− Do not damage the corrosion protection
(paint, surface coatings). Repair any
damage immediately.
−
Protect the control valve against moisture
and dirt.
− Observe the permissible temperature
range (see section 3.3).
4.2.2 Lifting
Lifting equipment (e.g. crane or forklift) can
be used to lift heavy control valves.
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. The
sling only protects the control valve from
tilting while being lifted. Before lifting the
control valve, tighten the sling.
