4 Shipment and on-site transport
The work described in this chapter may only be performed by
specialist personnel quali
fi ed to perform the corresponding task.
Damage to the ball valve due to improper transport and
storage!
Ö
Handle, transport and store ball valves with lining with par-
ticular care.
Ö
Use protective caps to protect the delicate sealing surfaces in
particular.
4.1 Accepting delivery
Perform the following steps after receiving the goods:
Ö
Check the scope of supply. Compare the delivered goods
with the delivery note.
Ö
Check the supply for transport damage. Report transport
damage to PFEIFFER and the transport company (see the de-
livery note).
4.2 Unpacking the ball valve
Carry out the following steps:
Ö
Unpack the ball valve directly before lifting for installation in-
to the pipe.
The packaging protects the scratch-sensitive plastic lining of the
ball valve against damage.
Ö
Leave the ball valve on the pallet or in the transport container
for on-site transport.
Ö
The protective caps on the ball valve inlet and outlet prevent
foreign matter from entering the ball valve and damaging it.
Furthermore, they are used to protect the sealing surfaces.
Only remove the protective caps prior to installation in the
pipe.
Ö
Dispose of the packaging properly.
4.3 Transporting and lifting the ball valve
Danger due to falling of suspended loads!
Do not stand under suspended loads.
NOTE
Info
DANGER
Overturning of the lifting equipment and damage to the load
lifting equipment by exceeding the lifting capacity!
− Only used approved lifting equipment and load lifting equip-
ment whose lifting capacity corresponds at least to the weight
of the ball valve including the actuator.
− Take the weights from the respective data sheet.
Danger of injury due to the tipping of the ball valve!
− Observe the centre of gravity of the ball valve.
− Secure the ball valve against tipping and twisting.
Damage to the ball valve due to improper fastening of the
sling!
The screwed-in lifting eyes on actuators are used only for actua-
tor assembling and disassembling as well as for lifting the actua-
tor without the ball valve. These lifting eyes are not intended for
lifting the complete ball valve.
− When lifting the ball valve, make sure that the entire load is
carried by the sling that is fastened to the ball valve body.
− Do not fasten the load-bearing sling to the actuator, hand
wheel or other components.
− Do not use the control air lines, accessories or other compo-
nents with safety functions for suspension or damage them.
4.3.1 Transporting
The ball valve can be transported using lifting equipment such as
a crane or a forklift.
Ö
Leave the ball valve on the pallet or in the transport container
for transport.
Ö
Ball valves that weigh more than approx. 10 kg should be
transported on a pallet (or supported similarly) (also to the
installation site). The packaging protects the scratch-sensitive
lining of the ball valve against damage.
Ö
Comply with the transport conditions.
Transport conditions
Ö
Protect the ball valve against external in fl uences, such as im-
pacts.
Ö
Do not damage the corrosion protection (paint, surface coat-
ing). Repair damage immediately.
Ö
Protect the ball valve against moisture and dirt.
4.3.2 Lifting
When installing the ball valve in the pipe, larger ball valves can
be lifted using lifting equipment such as a crane or forklift.
