2 Notes on safety
This operating manual contains fundamental
information which is to be observed during installa-
tion, 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 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 For the customer / operator
When using the valve, it must be ensured 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 usual flow rates are not exceeded in continu-
ous operation.
This is not the manufacturer's responsibility.
Fire protection to DIN EN ISO 10497 is not possible
(plastic lining and plastic components).
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.
