or FEP/PFA with metal core.
Test medium water 20 °C; depending on medium - e.g. dry gases or viscous or crystallising fluids - the torques may be higher. If the actuator is
to be rated by Richter, we request detailed information. Observe operating limits acc. to pressure-temperature diagram.
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 hazard-
ous substances.
2.1 Intended use
Sandwich ball valves of the series KK are flangeless
open/closed valves.
Richter sandwich ball valves of the series KK/KKP are
pressure containing components in accordance with
the Pressure Equipment Directive (PED) for the
passage and shut-off of fluids. 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.
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 manufac-
turer).
2.2 For the customer / operator
If a safety valve is used, the operator must ensure that
actuators which are retrofitted are adapted to suit
the valve
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).
