2 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 !
Peoples 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
hazardous substances.
2.1 Intended use
Richter safety valves of the series KSE/F and KSE-
C/F are pressure-maintaining components with safety
function in accordance with the Pressure Equipment
Directive (DGRL).
They protect the pressure equipment if the admissible
pressure limit is exceeded.
KSE/F and KSE-C/F are only intended for vertical
installation.
The valves are suitable for vapours, gases and liquids
of group 1 in accordance with the DGRL. They have a
corrosion-resistant plastic lining.
Safety valves are intended to prevent inadmissible
excessive pressures, e.g. in piping systems, pressure
vessel plants and boilers. Risks to people, the
environment and plants are thus avoided.
Solids can lead to increased wear, leaks, damage to
sealing surfaces or to a reduction in the service life of
the valve.
The safety valves have been set at the works to the
desired test pressure, tested and lead-sealed.
The precise operating conditions of the safety valve
selected are documented in the Data sheet. It also
contains the performance features such as the
certified coefficient of discharge, the flow cross area,
set pressure, opening pressure, reseating pressure
and materials.
If the valve is intended for other operating data, the
operator must carefully examine whether the design of
the valve, accessories and materials are suitable for
the new application.
2.2 For the customer / operator
If a safety valve is used, the operator must ensure that
hot or cold valve parts are protected by the
customer 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 name
plate must under no circumstances be
exceeded.
See also inadmissible modes of operation and their
consequences in Section 7.4.
