General
These operating instructions apply to KSB offset disc butterfly valves
(see section 6).
Design, manufacturing and testing of the KSB valves are subject to a
Quality Assurance System according to EN ISO 9001 and to the
European Pressure Equipment Directive 2014/68/EU (PED).
For a specific product configuration as an actuated valve, the
aggregate can be considered as a partly completed machine
according to the machinery directive 2006/42/EC and comply with the
requirements of the directive.
Correct installation and maintenance or repair are mandatory to
ensure trouble free operation of the valves.
The manufacturer cannot be made liable for these valves if operating
instructions are not being observed.
ATTENTION The valves must not be operated beyond the limits
defined in the operating instructions/contractual documentation/type
leaflet. Any use beyond the above conditions will lead to overload
which the valves cannot withstand.
Nonobservance of this warning may lead to personal injury or
property damage, e.g.:
-- Injury caused by escaping fluids (cold/hot, toxic,flammable,
corrosive or under pressure)
-- Incorrect operation or destruction of the valve.
The descriptions and instructions in this manual refer to the standard
versions but also apply to the related variants.
These operating instructions do not take into consideration:
-- incidents which may occur during installation, operation and
maintenance.
-- the local safety regulations. lt is the user’s responsibility to ensure
that these are also observed by the installation staff involved.
For actuated valves, the specified connection parameters and the
installation and maintenance instructions -- including the operating
manual for the actuator -- must be observed.
ATTENTION Handling a valve requires skilled and experienced
personnel.
The personnel 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, please contact
your KSB Sales Office.
For further questions and supplementary orders, especially when
ordering spare parts, please always state the indications of the
marking plate.
The specifications (operating data) of the valves are listed in the
technical documentation & type leaflet of the related valve (see also
section 6).
When returning valves to the manufacturer, please refer to section 6.

Safety
This manual contains basic instructions to be complied with during
operation and maintenance. lt is therefore vital for the fitter and the
operator/user to read this manual before installing/commissioning the
valve. Also, this manual must always be available at the site where the
valve is installed.
lt is not enough to observe the general instructions listed in the section
”safety”, the specific safety instructions listed in the other sections
should also be observed.
4.1.
Safety Symbols in these Operating
Instructions
Safety instructions put forth in this instruction manual, the
nonobservance of which would involve the risk of personal injury, they
are specially marked with the general hazard symbol:
in accordance with ISO 3864--B.3.1.
or with the electric voltage warning sign:
In accordance with ISO 3864--B.3.6.
Safety instructions the nonobservance of which would involve hazard
to the valve and jeopardize its operation have been marked with the
word
ATTENTION
lnstructions directly attached to the valve, (e.g. nominal pressure)
must be complied with and maintained in a legible condition.
4.2.
Qualification and training of personnel
The personnel for operation, maintenance, Inspection and installation
must be adequately qualified for the work involved. The personnel
responsibility, competence and supervision must be clearly defined by
the user. lf the personnel in question is not already in possession of the
required know-how, appropriate training and instructions must be
provided. lf deemed necessary, the manufacturer/supplier will provide
such training and instructions at the user’s request. In addition, the
user is responsible for ensuring that the contents of these operating
instructions are fully understood by the personnel involved.
4.3.
Danger or nonobservance of the safety
instructions
Nonobservance of the safety instructions may lead to personal injury
and danger for both the environment and the valve itself.
Nonobservance of these safety instructions will also forfeit the user’s
warranty.
Such noncompliance could result in for example :
-- failure of essential functions of the valve/plant
-- failure of prescribed maintenance and repair practices
-- hazard to people by electrical, mechanical or chemical effects
-- hazard to the environment due to leakage of hazardous substances
4.4.
Safety Consciousness
The safety instructions contained in this manual, the applicable
national accident prevention regulations and any of the user’s own
applicable internal work, operation or safety instructions must be fully
complied with.
4.5.
Safety Instructions for the User/Operator
Any hot or cold parts of the valve (e.g. body or handle or actuator) that
could cause a hazard must be protected by the user against accidental
contact.
Leakage of hazardous substance (e.g. flammable, corrosive, toxic,
hot) must be drained so as to avoid all danger to people or the
environment. All relevant laws must be observed.
Electrical hazards must be effectively prevented. (For details,
please refer to the IEC 364 or equivalent national standard and/or
local utility energy supply regulations).
