– Year of construction
– Valve body material
▪The operator is responsible for ensuring compliance with all local regulations not
taken into account.
▪The design, manufacture and testing of the valve are subject to a QM system to
DINENISO9001 as well as the current regulations and directives for pressure
equipment.
▪Bear in mind that valves exposed to creep-rupture conditions have a limited
service life and have to meet the applicable regulations stipulated in the
technical codes.
▪In the case of customised special variants, further restrictions may apply with
regard to the operating mode and service life. Refer to the relevant sales
documentation for applicable limitations.
▪The operator is responsible for any eventualities or incidents which may occur
during installation performed by the customer, operation and maintenance.
2.2 Intended use
▪Only operate valves which are in perfect technical condition.
▪Do not operate the valve in partially assembled condition.
▪Only use the valve for fluids specified in the product literature. Take the design
and material variant into account.
▪Only operate the valve within the operating limits described in the other
applicable documents.
▪The valve's design and rating are based on predominantly static loading in
accordance with the codes applied. Consult the manufacturer if the valve is
subjected to dynamic loads or any other additional influences.
▪Consult the manufacturer about any other modes of operation not described in
the product literature.
▪Do not use the valve as a foothold.

interaction between the valve and the system.
▪The responsibilities, competence and supervision of all personnel involved in
transport, installation, operation, maintenance and inspection must be clearly
defined by the operator.
▪Deficits in knowledge must be rectified by means of training and instruction
provided by sufficiently trained specialist personnel. If required, the operator can
commission the manufacturer/supplier to train the personnel.
▪Training on the valve must always be supervised by specialist technical personnel.
2.4 Consequences and risks caused by non-compliance with this manual
▪Non-compliance with these operating instructions will lead to forfeiture of
warranty cover and of any and all rights to claims for damages.
▪Non-compliance can, for example, have the following consequences:

2.5 Safety awareness
In addition to the safety information contained in this operating manual and the
intended use, the following safety regulations shall be complied with:
▪Accident prevention, health regulations and safety regulations
▪Explosion protection regulations
▪Safety regulations for handling hazardous substances
▪Applicable standards, directives and laws
2.6 Safety information for the operator/user
▪Actuator-operated valves are intended for use in areas which cannot be accessed
by unauthorised persons. Operation of these valves in areas accessible to
unauthorised persons is only permitted if appropriate protective devices are
fitted at the site. This must be ensured by the operator.
▪Fit protective equipment (e.g. contact guards) supplied by the operator for hot,
cold or moving parts, and check that the equipment functions properly. Do not
touch rotating parts.
▪Do not remove any protective equipment (e.g. contact guards) during operation.
▪Provide the personnel with protective equipment and make sure it is used.
▪Contain any leakage of hazardous fluids (e.g. explosive, toxic, hot) so as to avoid
any danger to persons and the environment. Adhere to all relevant laws.
▪Eliminate all electrical hazards. (In this respect refer to the applicable national
safety regulations and/or regulations issued by the local energy supply
companies.)

2 Safety
11 of 94
0570.82/17-EN
2.7 Safety information for maintenance, inspection and installation
▪Modifications or alterations of the valve require the manufacturer's prior
consent.
▪Use only original spare parts or parts/components authorised by the
manufacturer. The use of other parts/components can invalidate any liability of
the manufacturer for resulting damage.
▪The operator ensures that maintenance, inspection and installation are
performed by authorised, qualified specialist personnel who are thoroughly
familiar with the manual.
▪Carry out work on the valve during standstill only.
▪The valve body must have cooled down to ambient temperature.
▪The pressure in the valve body must have been released and the valve must have
been drained.
▪When taking the valve out of service always adhere to the procedure described
in the manual.
▪Decontaminate valves which handle fluids posing a health hazard.
▪Protect the valve body and body bonnet/cover from any impacts.
▪As soon as the work has been completed, re-install and re-activate any safety-
relevant devices and protective devices. Before returning the product to service,
observe all instructions on commissioning. (ðSection6.1,Page43)
2.8 Unauthorised modes of operation

3.1 Checking the condition upon delivery
1. On transfer of goods, check each packaging unit for damage.
2. In the event of in-transit damage, assess the exact damage, document it and
notify KSB or the supplying dealer and the insurer about the damage in writing
immediately.
3.2 Transport
Transport the valve in the closed position.
DANGER
The valve could slip out of the suspension arrangement
Danger to life from falling parts!
▷Only transport the valve in the specified position.
▷Never attach lifting accessories to the handwheel.
▷Observe the information on weights, centre of gravity and fastening points.
▷Observe the applicable local accident prevention regulations.
▷Use suitable, permitted lifting accessories, e.g. self-tightening lifting tongs.
▷For valves with actuators observe the relevant actuator operating manual.
Transport aids on the actuator are not suitable for suspending the entire valve/
actuator assembly.
To transport the valve, suspend it from the lifting tackle as illustrated.

0570.82/17-EN
3.3 Storage/preservation
If commissioning is to take place some time after delivery, we recommend that the
following measures be taken for storing the valve:
CAUTION
Incorrect storage
Damage due to dirt, corrosion, humidity and/or frost!
▷Close the valve using little force and store in the closed position.
▷Store the valve in a frost-proof room where the atmospheric humidity is as
constant as possible.
▷Protect the valve from dust during storage, e.g. with suitable caps or foils.
▷Protect the valve from contact with solvents, lubricants, fuels or other
chemicals.
▷Store the valve in vibration-free conditions.
If properly stored indoors, the equipment is protected for a maximum of 12 months.
NOTE
If the valves are fitted with actuators, ensure that the actuator's operating manual
is also observed.
3.4 Return to supplier
1. Drain the valve as described in the manual.
2. Flush and clean the valve, particularly if it has been used for handling noxious,
explosive, hot or other hazardous fluids.
3. If the valve has handled fluids whose residues could lead to corrosion damage in
the presence of atmospheric humidity or could ignite upon contact with oxygen
also neutralise the valve and blow through with anhydrous inert gas to ensure
drying.
4. When returning valves used for handling Fluids in Group1 always complete and
enclose a certificate of decontamination.
Indicate any safety measures and decontamination measures taken.
NOTE
If required, a blank certificate of decontamination can be downloaded from the
following web site: www.ksb.com/certificate_of_decontamination

4.3.1.3 Function
Design The globe valve comprises the pressure-retaining parts, i. e. body 100 and yoke 166,
the functional unit (stem 200 and valve disc 350/352) and the actuating element.
Sealing Body 100 and yoke 166 are joined by studs 902 and nuts 920.1, and the joint is sealed
to atmosphere by joint ring 411.
The passage of stem 200 in yoke 166 is sealed by gland packing 461, which is
tightened via gland follower 452 by means of two nuts 920.2.
The seating faces of body 100 and/or valve disc 350 are made of stainless materials.
