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, operation and maintenance 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 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
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-
dous substances.
2.1 Intended use
Richter sampling valves are pressure-maintaining
components in accordance with the Pressure
Equipment Directive (DGRL) for taking liquid samples.
The standard PA/F and PA/S are only intended for
horizontal installation (vertical installation only with
special adapter).
The valves are suitable for non-boiling liquids of group
1 in accordance with the Pressure Equipment
Directive.
Solids can lead to increased wear, damage to sealing
surfaces or to a reduction in the service life of the
valve.
The operator must carefully examine in the event of
operating data other than those provided whether the
designs of the valve, accessories and materials are
suitable for the new application (consult the
manufacturer).
