5 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 measures
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 regula-
tions.
Neutralise any medium residues in the valve.
Separate valve materials (plastics, metals, etc.)
and dispose of them in accordance with the local
regulations.
6 Installation
Examine valve for in-transit damage, damaged
bellows control valves must not be installed.
Before installation the valve and the connecting
pipe must be carefully cleaned to remove any dirt,
especially hard foreign matter.
During installation, pay attention to the correct
tightening torque, aligned pipes and tension-free
assembly.
The all-round gap between the body and the cover
must remain constant so that a centric position of
the plug in relation to the seat is guaranteed.
Operation during maintenance work can be
continued with a bypass around the control valve.
Ensure that a remotely actuated actuator
cannot be accidentally switched on.
Depending on the kv-value, the free cross section
in the valve may be much smaller than the cross
section of the nominal size. To prevent clogging,
the pipe must be carefully cleaned upstream of the
valve.
6.1 Flange caps and gaskets
Leave protective caps on the flanges until just prior to
installation.
Where there is a particularly high risk of damage to
the plastic sealing surfaces, e.g. if the mating flanges
are made of metal or enamel, PTFE-lined gaskets with
a metal inlay should be used. These gaskets are
available as special accessories in the Richter range.
