4 Safety note for valves, certified to German Clean Air Act
(TA Luft)
On request, this valve can be supplied compliant with
the German Clean Air Code.
Certificate / Manufacturer Declaration Validity is
dependent on the operating instructions being read
and observed. In particular, servicing must be conducted at regular
intervals, and the bolted connections relevant for
tightness must be inspected and retightened if nec-
essary.
5 Transport and storage
It is imperative, for all transport work, to
observe generally accepted engineering
practice and the accident prevention regula-
tions.
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.
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.
6 Installation
Examine valve for in-transit damage, damaged
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
tighening torque, aligned pipes and tension-free
assembly.
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.
6.2 Direction of flow and
installation position
The installation position of the check valve RV is only
possible in a vertical pipe.
The direction of flow is marked on the valve, the shut-
off operation is already initiated by the weight of the
shut-off element when delivery decreases.
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.
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.
