Transport, storage and disposal
It is imperative, for all transport work, to
observe generally accepted engineering
practice and the accident prevention
regulations.
The valve is supplied with flange caps. Do
not remove them until just before installation.
They protect the plastic surfaces against dirt
and mechanical damage.
Handle the goods being transported with care. During
transport the valve must be protected against impacts
and collisions.
Directly after receipt of the goods, the consignment
must be checked for completeness and any in-transit
damage.
Do not damage paint protection.
5.1 Storage
If the valve is not installed immediately after delivery,
it must be put into proper storage.
It should be stored in a dry, vibration-free and well-
ventilated room at as constant a temperature as
possible.
Elastomers are to be protected against UV light.
In general, a storage period of 10 years should not be
exceeded.
5.2 Return consignments
Valves which have conveyed aggressive or
toxic media must be well rinsed and cleaned
before being returned to the manufacturer's
works.
It is
imperative
to enclose a
safety information
sheet / general safety certificate
on the field of
application with the return consignment.
Pre-printed forms are enclosed with the installation
and operating manual.
Safety precautions and decontamination methods are
to be mentioned.
5.3 Disposal
Parts of the valve may be contaminated with medium
which is detrimental to health and the environment
and therefore cleaning is not sufficient.
Risk of personal injury or damage to the
environment due to the medium!
♦
Wear protective clothing when work is performed
on the valve.
♦
Prior to the disposal of the valve:
▪
Collect any medium, etc. which has escaped
and dispose of it in accordance with the local
regulations.
▪
Neutralise any medium residues in the valve.
♦
Separate valve materials (plastics, metals, etc.)
and dispose of them in accordance with the local
