Preparation
− 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 liftling eyelet and rigging
equipment (hook, shackle etc.) does not
bear any load when lifting control valves
with 116 in² (750 cm²) actuators. The
sling only protects the control valve from
tilting while being lifted. Before lifting the
control valve, tighten the sling.
