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 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!
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.
When using the valve, it must be ensured 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 usual flow rates are not exceeded in continuous
operation.
This is not the manufacturer's responsibility.
Ball valves which are used as end valves
must be sealed with a blind flange at the free
connection end or appropriately secured
against unauthorised actuation.
Fire protection to DIN EN ISO 10497 is not possible
(plastic lining and plastic components).
2.1 Intended use
Ball valves are on/off valves.
Richter bottom drain ball valves of the seriesKA-
N/KNP 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 Inadmissible modes of
operation
The operational reliability of the valve supplied is only
guaranteed if it is used properly in accordance with
Section 1.1 of this operating manual.
The operation limits specified on the
identification plate and in the pressure-
temperature diagram must under no
circumstances be exceeded.
