4 Transport and storage
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.
4.1 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.
4.2 Return consignments
Valves which have conveyed aggressive or
toxic media must be well rinsed and cleaned
before being returned to the manufacturer's
works.
A General Safety Certificate on the field of
application is to be enclosed with the returned goods.
Pre-printed forms are enclosed with the installation
and operating manual.
Safety precautions and decontamination measures
are to be mentioned.
5 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.
It the cover is provided with an alarm
connection, it must also be connected or
sealed. Otherwise medium could escape if
the bellows are defective.
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.
5.1 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 ITT Richter
range.
5.2 Direction of flow and installa-
tion position
Installation is independent of the direction of flow.
Any installation position can be chosen.
Otherwise, it is marked by a direction arrow on the
ball valve, e.g. in the case of cavity-free ball/stem
units.
5.3 Grounding
If the plant requires grounding the easiest solution is
to place a toothed lock washer under the nut of a
pipeline bolt of each valve flange.
Otherwise grounding must be ensured by different
measures e.g. a cable link.
5.4 Test pressure
The test pressure PT of an open valve must not
exceed the value of 1.5 x PN/PS as per the identifica-
tion of the valve.
