Measures for preparation
Fig. 4: Lifting points on the control valve: up to NPS 6 (left) and with welding ends (middle) · NPS 6
and larger with additional lifting eyelet on the actuator (right)
− 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 larger
than NPS 6. The sling only protects the
control valve from tilting while being lift-
ed. Before lifting the control valve, tight-
en the sling.
