Figure | 4-1: Lifting points on the ball valve
Conditions for lifting
Ö
Use a hook with a safety clamp as the suspension element so
that the sling cannot slip off the hook during lifting and trans-
port, see Figure 4-1.
Ö
Secure the sling against shifting and slipping off.
Ö
Fasten the sling such that it can be removed again after in-
stallation in the pipe.
Ö
Avoid swinging and tipping the ball valve.
Ö
In the case of interruptions in work, do not leave the lifting
equipment suspended in the air for a long period of time.
Ö
Lift the ball valve aligned in the same direction in which it will
be installed in the pipe.
Ö
Always lift the ball valve in the centre of gravity of the load to
prevent uncontrolled tipping.
Ö
Make sure that any slings between the lifting eyes on the ro-
tary actuator and suspension element are not loaded. These
slings are used only to secure the load against turning over
while lifting. Before lifting the ball valve, pretension this sling
so it is taut.
Danger due to incorrect lifting and transport!
The lifting points for the lifting slings shown in the schematic
drawing serve as examples for most valve variants. On site the
conditions for lifting and transporting the valve can change how-
ever.
Ö
The operator makes sure that the valve is lifted and transport-
ed safely.
WARNING
4.3.3 Lifting points on the body
Ö
Fasten a lifting sling to each fl ange of the housing and on the
suspension element (e.g. hook) of the crane or forklift, see
Figure 4-1. When doing so, ensure the safety, bearing ca-
pacity and length of the lifting slings
Ö
In the case of an actuator with a lifting eye: fasten additional
lifting slings to the lifting eye on the actuator and on the sus-
pension element.
Ö
Lift the ball valve carefully. Check if the load lifting equipment
holds.
Ö
Move the ball valve at a constant speed to the installation
site.
Ö
Install the ball valve in the pipe , see chapter 5.4.
Ö
After installation in the pipe: check that the fl anges are fi rmly
tightened and that the ball valve holds in the pipe.
Ö
Remove the lifting slings.
4.3.4 Lifting points on the bracket
Ö
Fasten a lifting sling to the bracket and the suspension ele-
ment (e.g. hook) of the crane or forklift, see Figure 4-1.
When doing so, ensure the safety, bearing capacity and
length of the lifting slings.
Ö
In the case of an actuator with a lifting eye: fasten additional
lifting slings to the lifting eye on the actuator and on the sus-
pension element.
