2 Notes on safety
This operating manual contains fundamental
information which is to be observed during installation,
operation 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 valve and its function
may be put at risk if this safety symbol is not
observed.
It is imperative to observe warnings and signs
attached directly to the ball valve and they are to be
kept fully legible.
Failure to heed and follow these notes on
safety may cause damages to persons and
property!
The manufacturer is not responsible for and her
disclaims all damages resulting from a failure to
observe adequate safety precautions in connection
with the operation, maintenance and repair of the
valves!
For example, non-observance may involve the
following 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 hazar
ous substances.
2.1 Intended use
Ball valves are on/off valves.
Richter ball valves are pressure containing comp
nents in accordance with the Pressure Equipment
Directive (PED) for the passage and shut
The valves are suitable for vapours, gases and non
boiling liquids of group 1 according to the PED and
have a corrosion-resistant plastic lining.
Solids can lead to increased wear, damage to sealing
surfaces or to a reduction in the service life of the
valve.

preferred for corrosive atmosphere and in clean
conditions.
2.2 For the customer / operator
When using the valve, it must be ensured tha
actuators which are retrofitted are adapted to suit
the valve
hot or cold valve parts are
protected by the customer
against being touched
the ball valve has been properly installed in the
pipe system
the usual flow rates are not exceeded in cont
nuous operation.
This is not the manufacturer's responsibility.
Loads caused by earthquakes were not allowed for in
the design.
Ball valves which are used as end valves
must be sealed with a blind flange at the free
connection end
against unauthorised activation.
Fire protection to DIN EN ISO 10497 is not possible
(plastic lining and plastic components).
2.3 Improper operation
Permitted operation of these valves is limited to the
intended purpose, as shown
operating instructions.
Under no circumstances must the operating
parameters specified on the identification
plate and in the pressure
diagram be exceeded.
Failure to operate the valves within the operating
parameters voids the warranty!
See also improper operation and their consequences
in Section 7.4.
