2 Notes on safety
This operating manual contains fundamental informa-
tion which is to be observed during installation, opera-
tion and maintenance. It must therefore be read
before installation and commissioning.
For valves which are used in potentially explosive
areas, see Section 3.
Installation and operation are to be performed by
qualified staff.
The area of responsibility, authority and supervision of
the staff must be regulated by the customer.
General hazard symbol!
People may be put at risk.
Safety symbol! The ball valve and its func-
tion may be put at risk if this safety symbol is
not observed.
It is imperative to observe warnings and signs at-
tached directly to the ball valve and they are to be
kept fully legible.
Non-observance of the notes on safety may result
in the loss of any and all claims for damages.
For example, non-observance may involve the follow-
ing hazards:
Failure of important functions of the valve/plant.
Risk to people from electric, mechanical and
chemical effects.
Risk to the environment through leaks of hazard-
ous substances.
2.1 Intended use
Richter check valves of the series RV are pressure
relief components in accordance with the Pressure
Equipment Directive (PED) for the passage of fluids in
the direction of the flow arrow on the body and for the
shut-off of fluids in the opposite direction.
However, shut-off of the passage of fluids in the
opposite direction may be cancelled out, depending
on the installation position, ball design, differential
pressure and fluid.
The valves are suitable for vapours, gases and liquids
of group 1 in accordance with the PED and have a
corrosion-resistant plastic lining.
Solids can lead to increased wear, leaks, damage to
sealing surfaces or to a reduction in the service life of
the valve.
In case of the valve is intended for operating data
other than those intended, the customer must
carefully examine whether the design of the valve,
accessories and materials are suitable for the new
application (consult the manufacturer).
2.2 For the customer / operator
If a safety valve is used, the operator must ensure that
actuators which are retrofitted are adapted to suit
the valve
hot or cold valve parts are protected by the cus-
tomer against being touched
the valve has been properly installed in the pipe
system
the operating conditions stipulated in the data
sheet are not exceeded in continuous operating
mode.
This is not the manufacturer's responsibility.
Loads caused by earthquakes were not allowed for in
the design.
Fire protection to DIN EN ISO 10497 is not possible
(plastic lining and plastic components).
2.3 Improper operation
The operational reliability of the valve supplied is only
guaranteed if it is used properly in accordance with
Section 2.1 of this operating manual.
The operation limits specified on the identifi-
cation plate and in the pressure-temperature
diagram must under no circumstances be
exceeded.
