These operatinginstructions applyto KSB offset disc butterfly valves
Design,
manufacturing
andtestingof the KSB valvesare subjecttoa
Quality Assurance System according to EN ISO 9001 and to the
European Pressure Equipment Directive 2014/68/EU (PED).
Correct installation and maintenance or repair are mandatory to
ensure trouble free operation of the valves.
The
manufacturer

or with the electric voltage warning sign:
Nonobservance
of thiswarningmayleadtopersonalinjuryor
property damage, e.g.:
- Injury caused by escaping fluids (cold/hot, toxic, flammable,

in
charge
of
operation, maintenance
and
installation
of
this valve must be aware of the
interaction
between the valve and the
plant.
Operator’s errors concerning the valve may have serious
consequences for the entire plant, e.g.:
- fluid may escape
- downtime of the plant/machine
- adverse effect/reduction/increase of the efficiency/function of a
plant/machine.
For
further
questions
or
in
case
of
damage
to
the
valve,
