History
With decades of expertise in thermodynamics,
Sempell provides turbine bypass and startup control
valves with unparalleled reliability to the OEM’s plant
design engineer for applications in supercritical and
ultra-supercritical power plants.
In addition, Sempell forged gate, globe and check
valves serve the DIN and ASME power generation
markets. Applying cutting edge material science and
valve designs, Sempell isolation and non-return valves
are designed for all types of power plants, including
nuclear and supercritical plants, which operate at
temperatures up to 720° C.
Within the nuclear power generation segment,
Sempell pioneered new technology for pilot operated
pressurizer safety valve systems on the new GEN III
reactors, regardless of code. Sempell also provides
other critical solutions for the nuclear industry,
including system medium operated main steam
isolation valves and pilot operated main steam safety
valves.

SAFETY VALVES
Safety valves are used to protect systems against overpressure
and to blow-off the required capacity of the system medium.
The requirements for safety relief valves on boilers application
are described in TRD 421 and the US code ASME Section I. For
process industry the standards are AD 2000 resp. ASME VIII.
Together with the Pressure Equipment Directive a complete set
of european standards will be established. The standard ISO EN
4126 part 1 to 7 defines the different types of safety devices.
In the process industry besides spring loaded safety valves also
pilot operated valves are used.
For the protection of boilers – because of the high operation
forces – the use of disc type springs enables to install large
loaded safety valves also on high pressures. According to the
German standards these safety valves will in most cases be
equipped with a pneumatic actuator where a supplementary
closing force is obtained and the valve can be opened at
pressure below. By means of these pneumatic support, – i.e.
superheater and reheater safety – valves, with high pressure
loss at the inlet, can be kept in a stable open position.
In addition, Sempell offers pilot operated safety valves, which
are medium operated according to the relieving principle.
For very small blow-off capacities and for protection of
liquids, safety valves with small diameters, also call thermal
expansion valves, are used.
For valves sizing and selection, the Sempell software package
“BABSY” is available.

Control units for spring loaded safety valves
Type STE4
pneumatic control unit for spring loaded safety
valves
The efficiency of plant operation can be increased by application of
pneumatically assisted operation on a spring loaded safety valve.
The advantages of direct acting safety valve will be combined with
the advantages of controlled safety valves.
With the control unit STE4 a fully TÜV type tested system is
available. All control paths are three times redundant and the
unit is working according to the fail safe principle. The functions
pressure sensing, electrical control and pneumatic operation are
split in separate housings. This modular design enables a high

Safety valve testing
Type SESITEST
Mobile test equipment for safety valves
With SESITEST time and costs can be reduced significantly during
plant shut-down.
SESITEST enables the accurate assessment of set-pressure and
other safety valve functional characteristics in situ under normal
operating plant conditions. With SESITEST there is no need to raise
the line pressure or to remove the valve from the plant.
An air operated, low friction piston entes an opening force to
the stem of the safety valve. This force makes up the difference
between the system pressure and the set pressure. The signals are
recorded on the connected Computer and the valve characteristics
are determined automatically online. The system is very open,
all signals can be visualized each time and there are many tools
available for analysis and documentation.
The software SESI has been specially designed by SEMPELL and
incorporates our vast experience in operating and testing safety
relief valves. The software also allows the selection of various test
sequences and output documentation formats, and includes a
database in which valve identification and test data can be stored
furthermore additional graphical analysis and calculations can be
carried out with our software package.
