General
These operating instructions apply to KSB – forged steel
gate, globe and check valves.
Development and production of KSB valves are subject to a
QA system according to DIN/ISO 9001.
Correct installation and maintenance or repair will ensure
trouble free operation of the valves.
The manufacturer does not assume any liability for these
valves if the operating instructions are not being observed.
The valves are marked to ASME B16.34 if
required with an arrow indicating the flow
direction, Nominal size, Class, material of body,
manufacturer.
The valves must not be operated beyond the limits defined in
the operating instructions/contractual documentation/type
series booklet. Any use beyond the above conditions will
lead to overload which the valves cannot withstand.
Non-observance of this warning may lead to
personal injury or property damage, e.g.:
- Injury caused by escaping fluids (cold/hot, toxic 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 consider:
- incidents which may occur during installation, operation and
maintenance.
- the local safety regulations. It is the user’s responsibility to
ensure that they are observed, also 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.
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.
The specifications (operating data) of the valves are listed in
the technical documentation & type series booklet of the
related valve (see also section 5).
When returning valves to the manufacturer, please refer to
section 4.
The manufacturer is not liable for any claims
resulting from a failure to implement or
implement properly the instructions contained in these
operating instructions or resulting from the actions of a third
party.
In particular, the manufacturer is not liable
for direct or indirect consequential damage
that has occurred for whatever reason.

Safety
This manual contains basic instructions to be complied with
during operation and maintenance. It 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.
It 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.
