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.
Failure to heed and follow these notes on
safety may cause damages to persons
and property!
The manufacturer is not responsible for and
hereby 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
hazardous substances.
2.1 Intended use
Richter safety relief valves of the series KSEA/F are
Pressure Relief Devices in accordance with the ASME
Boiler & Pressure Vessel Code Section VIII,
Division 1. They protect the pressure equipment if the
admissible pressure limit is exceeded.
KSEA/F are only intended for vertical installation.
The valves are suitable for vapours, gases and
liquids. 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 Inspection 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
Permitted operation of these valves is limited to the
intended purpose, as shown in Section 2.1 of these
operating instructions.
Under no circumstances must the operating
parameters specified on the identification
plate and in the pressure-temperature
diagram be exceeded.
Failure to operate the valves within the operating
parameters voids the warranty!

in Section 7.4.
