The factory-applied corrosion protection and any assemblies
must be protected against damage by external influences during
transport and storage.
The VAG CEREX
300 Butterfly Valve must be transported with the
®
disk slightly open. For this purpose, place the valve on one of its
two flanges (cf. Figure 1 and Figure 2).
If the valve is supplied with mounted actuators, ensure safe stor-
age of the actuators to prevent transverse loads acting on the
connection points.
When selecting and using slings, observe the weight and the type
of sling. The use of the slings should comply with the usual regu-
lations.
VAG CEREX
300 Butterfly Valves with large nominal diameters
®
have en eccentric centre of gravity. If improper slings are used, the
valves may swing to the side while being lifted.
Never lift or lower the load abruptly as the forces occurring may
damage both the valve and the lifting equipment.
For transport purposes and also to support assembly, lifting de-
vices such as cables and belts must only be attached to the body
of the valve or the bearing lugs. The length and positioning of the
cables/belts must ensure that the valve is in a horizontal position
during the entire lifting procedure.
The general regulations relating to the use of lifting equipment
must be complied with.
For valves that have been factory-packed in transport crates
(wooden crates), the centre of gravity of the entire unit must be
taken into account. The centre of gravity is marked on each side
of the crate at our factory and must be considered for all lifting
operations.

2.2 Storage
The VAG CEREX
300 Butterfly Valve has to be stored with its disk
®
slightly open (see Figure 2).

Figure 2: : Storage with the disk slightly open
The elastomeric parts (seals) must be protected against direct
sunlight and/or UV light as otherwise their long-term sealing func-
tion cannot be guaranteed. Store the valve in a dry and well-aer-
ated place and avoid direct radiator heat. Protect any assembly
units important for the function such as the disk and the profiled
seal against dust and other dirt by adequate covering.
Do not remove the protective caps of the connections / flanges
and the packaging materials until immediately prior to assembly.
The valve can be stored in ambient temperatures ranging from
-20 °C to + 50 °C (protected by adequate covers). If the valve is
stored at temperatures below 0 °C, it should be warmed up to at
least +5° C before installation and before it is put into operation.
