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
regulations.
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
globe shut-off or 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.
6.1 Flange caps and gaskets
Leave protective caps on the flanges until just prior to
installation.
If plastic sealing surfaces can be damaged, e.g. with
mating flanges made of metal or enamel, use PTFE-
lined seals with a metal inlay.
These are available as special accessories from the
Richter product range.
6.2 Direction of flow and
installation position
The direction of flow must be observed when installing
the valve.
It is indicated by a direction arrow on the valve shell.
6.3 Grounding
The valve must be grounded. The simplest solution is
to use tooth lock washers which are placed under one
pipe bolt of each flange.
At the customer's request a setscrew M6 with a hex.
nut and washer will be provided at each flange as an
additional grounding connection.
Otherwise grounding must be ensured by different
measures e.g. a cable link.
6.4 Test pressure
The test pressure PT of a valve must not exceed the
value of 1.5 x PS(PN) as per the identification of the
valve.
