operation and maintenance.
It must be read before installation and
commissioning!

areas, see Section 3.
Installation and operation are to be performed by

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.

in the loss of any and all claims for damages.
For example, non-observance may involve the
following hazards as:
Failure of important functions of the valve/plant.
Risk to people from electric, mechanical and
chemical effects.
Risk to the environment through leaks of hazar-
