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.
It is not permitted to put the valve into store with the
disc completely closed or with an opening angle
greater than 15°.
5.2 Transport preparations
During transport the disc/stem unit must not project
beyond the body dimensions.
Hand lever:
When the valve is in the closed position, the lever is to
lock in the first lever catch. This results in the
disc/stem unit being slightly opened.
Worm gear
When the valve is in the closed position, the disc/stem
unit is to be 10-15° open.
Actuator
When the valve is in the closed position, the disc/stem
unit is to be 10-15° open.
Attach a locking plate on shut-off and control butterfly
valves with a single-acting actuator. See also

Mount flange caps.
5.3 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 measures
are to be mentioned.
5.4 Transport securing device
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
regulations.
