Notes on safety
This
operating
manual
contains
fundamental
information which is to be observed during installation,
operation and maintenance.
It
must
be
read
before
installation
and
commissioning!
This operating manual must always be available at the
place of use of the valve.
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 ball 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 ball 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
Ball valves are on/off valves.
Richter ball valves are pressure containing compo-
nents 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
manufacturer).
Ball valves of the series KNA-S/F and KNAP-S/F are
preferred for corrosive atmosphere and in clean-room
conditions.
2.2 For the customer / operator
If a 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 usual flow rates are not exceeded in continu-
ous operation.
This is not the manufacturer's responsibility.
Loads caused by earthquakes were not allowed for in
the design.
Ball valves at the end of a pipe (end valve)
must be sealed with a blind flange at the
free connection end and appropriately
secured against unauthorised activation.
Fire protection to DIN EN ISO 10497 is not possible
(plastic lining and plastic components).
2.3 Improper operation
The operational safety 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 and in the pressure-temperature
diagram must under no circumstances be
exceeded.
