All forged valves have been designed according to the
following standards and specifications: ASME B16.34, API
602.
Forged valves mainly consist of body, bonnet and the closing
as well as the actuating unit (only gate and globe valves).
Stem seal area: The gland packing of gate and globe valves
which seals the stem is tightened by the studs and nuts on
the gland flange. The bonnet is equipped with an integral
back seat, which seats the valve when stem is in upmost
position.
Flow seal area: The hard faced seat rings of gate valves and
swing check valves are swagged into the body. The solid
wedge of gate valves is connected to the stem by a “T” joint.
The integral seal faces of the body of globe and piston check
valves are hard faced. The turning disc of globe valves is
connected to the stem by a “T” joint. The disc of piston check
valves is spring loaded.
Bonnet seal area: The bonnet/yoke of class 800 valves is
bolted to the body. In some cases the bonnet or cover is seal
welded to the body upon the request of customer/order.
6 Installation
6.1 General
To avoid leakage, deformation or rupture of the
body, the piping should be laid out in such a way that no
thrust or bending forces act on the valve bodies (100) when
they are installed and operational.
Only remove the covers from the connection
ends just before installation. The sealing faces
of the flanges must be clean and undamaged.
The gaskets at the connecting flanges must be
precisely entered. Use only joints and gaskets of
approved materials. All holes provided in the flanges must be
used for the flange connection.
When painting the pipes, do not apply paint to
bolts and stem (200). If construction work is still in
progress, the valves must be protected against dust, sand
and building material etc. (cover with suitable means).
Do not use valve hand-wheels as footholds!
Valves and pipes used for high (>50℃) or low
(<0℃) temperatures must either be fitted with a
protective insulation, or there must be warning signs installed
showing that it is dangerous to touch these valves.
If a valve is used as end-valve in a pipe, this valve
should be protected against unauthorized or
unintentional opening to prevent personal injury or damage
to property.
Caution
Caution

6.2 Installation position
The valve bodies are marked with an arrow indicating the
flow direction. Valves should always be installed in such a
way that the actual flow direction of the medium matches the
arrow on the body.
6.2.1 Gate valves
In general flow may pass a gate valve in either direction.
However in high pressure valves with pressure relieving
arrangement valves are unidirectional. When installing a
gate valve in a horizontal pipe, the stem should be vertical,
i.e. the handwheel or actuator is on top. Inclined or horizontal
stem position (e.g. in a vertical pipe) is also possible, in this
case, however, the actuator must be supported by some
suitable means.
6.2.2 Globe valves
Flow may pass a globe valve in either direction if not
indicated otherwise. When installing a globe valve in a
horizontal stem position (e.g. in a vertical pipe) is also
possible, in this case, however, the actuator must be
supported by some suitable means.
6.2.3 Swing Check valves
Swing check valves should preferably be installed in
horizontal pipes. When installing them in vertical pipes, make
sure that the flow direction is upward, so that in the
unpressurized condition, the disc will be closed by its own
weight.
6.2.4 Piston Check valves
Piston check valves should preferably be installed in
horizontal pipes. Installing them in vertical pipes is not
allowed because the blocking between disc and body may
occur.
6.3 Welding instructions / installation of pipe
Responsibility for welding the pipes lies with the piping
installation contractor.
When welding valves on to the piping or when
welding pipes after the valves have been
installed, the welder must make sure that no foreign particles,
e.g. weld beads, enter the valve body and remain there,
because these will cause damage to the valve seats and or
the valve stem.
When welding these valves, use adequate
precautions, e.g. welding in several steps, to
make sure that the temperature in the middle of the body
does not rise above 80to 100. Gate valves / Globe valves
must be in open position during welding to prevent the
sealing elements from contacting body sealing surface
otherwise the seats may be welded together.
Do not attach the welding cables (opposite
pole) to the moveable parts of the valve,
otherwise these parts may be scorched.
6.4 Actuated valves
Read the instruction manual of the actuator
before installation.
Electrical cables may only be connected by
qualified personnel.
The applicable electrical regulations (e.g. VDE),
also for equipment in hazardous locations, must
be observed.
All electrical equipment such as actuator, switchboard,
magnetic valve drive, limit switch etc. must be installed in
floodproof dry locations.
Voltage and frequency must match the valves stated on the
name plate.
7 Commissioning / Decommissioning
7.1 Commissioning
7.1.1 General
Prior to commissioning the valve, the pressure, temperature
and material data stated on the valve should be compared to
the actual operating conditions in the piping system to check
whether the valve can withstand the loads occurring in the
system.
Possible pressure surges (water hammer) must not
be exceed the highest admissible pressure.
Adequate precautions should be taken.
Caution
Caution
Caution
Caution

In new pipe systems and especially after repair work, the
system should be flushed with the valves fully open to
remove solids, e.g. weld beads, which may damage the
seats.
7.1.2 Operation
The valves are closed by turning the handwheel in the
clockwise direction (top view) and opened in the counter
clockwise direction.
Using additional levers when turning the
handwheel is not admissible, because excess
force may damage the valve.
7.1.3 Functional Check
The following functions should be checked:
Before commissioning, the shut-off-function of the valves
should be checked by repeated opening and closing.
The gland packing (461) should be checked when it is
subjected to the full operating pressure and temperature for
the first time. If necessary, retighten the nuts (920) at the
gland flange (452) evenly.
The cover flange connection (901) and the gasket (411)
should be checked for tightness after the first temperature
rise at the valves. In case of leakage at the gasket (411), the
connection should be tightened crosswise, evenly and in a
clockwise direction.
Open the gate and globe valve by one or two
turns of the handwheel prior to retightening the
nuts 920 to prevent jamming of the seat.
Retightening of the nuts (901) of the cover bolting especially
applies to valves used in heat transfer systems to DIN 4754.
7.1.4 Actuated valves
On valves with electric/pneumatic/hydraulic actuator, the
strokes/forces must be limited.
Electric actuators should be wired as follows:
Always use suitable spare parts and tools, even in
emergencies, because otherwise correct operation of the
valves cannot be assured.
Switches are factory set. Do not tamper with
settings. To readjust settings refer instruction
manual of actuator manufacturer and / or contact your
nearest KSB office.
For setting of actuator, please refer instruction manual which
will be kept in the wiring side compartment/cover of actuator.
7.2 Decommissioning
During extended shutdowns periods, liquids liable to change
their condition due to polymerization, crystallization,
solidification etc. must be drained from the piping system. If
necessary, the piping system should be flushed with the
valves fully open.
8 Maintenance/Repair
8.1 Safety Instructions
Maintenance and repair work may only be carried out by
skilled and qualified personnel.
For all maintenance and repair work, the safety instructions
listed below and also the general notes in section 3 must be
observed.
Always use suitable spare parts and tools, even in
emergencies, because otherwise correct operation of the
valves can not be assured.
8.1.1 Dismantling of valves
Before removing the complete valve from the pipe, or before
repair or maintenance work on the valve itself, i.e.
- before removing cover or bonnet from the body
- before removing the gland flange and gland bush to replace
packing rings
- before removing an actuator bolted directly to the yoke
head
The entire valve must be unpressurized and must
have cooled down sufficiently so that the
temperature of the medium in all the valve’s chambers is
lower than the vaporization point of the medium, to prevent
scalding.
Opening pressurized valves will cause danger to
life and limb!
If toxic or highly inflammable substances or liquids whose
residues may cause corrosion by interaction with the air
humidity were handled by the valve, then the valve should be
drained and flushed or vented.
If necessary, wear safety clothing and a face guard/mask.
Caution
Caution
Caution

Depending on the installation position, any liquid remaining
in the valve may have to be removed.
Prior to possible transport, the valves must be flushed and
drained carefully.
If you have any questions, please contact your KSB Sales
Office.
8.1.2 Removing Actuators
If actuators powered by an external source of
energy (electric, pneumatic, hydraulic) need to be
removed from the valves or dismantled, the energy supply
must be shut down prior to starting any repair work and the
instructions in the sections 3, 8.1.1 and the operating
instructions of the actuator must be observed.
Valve actuators with integrated spring-loading
feature cannot be removed.
Springs under tension!
If you have any questions, please contact your KSB Sales
Office.
8.2 Maintenance
Our valves are largely maintenance free, materials of sliding
parts were selected to keep wear to a minimum. To ensure
reliable operation and to reduce repair costs, all valves -
especially those which are seldom operated or where access
is difficult -should be checked periodically.
The user is responsible for defining appropriate intervals for
checks and maintenance, depending on the application of
the valve.
The service life of non-maintenance-free valves can be
extended by:
- lubricating movable parts such as stem (200) and gland
bolts (not for oxygen valves) and provided in the case of gate
valve using suitable lubricants to DIN 51825 / equivalent
- timely changing of the packing rings
- timely replacing of the cover gasket (411)
The safety instructions in sections 3, 8.1 and the notes in
section 9 must be observed.
8.3 Valve Reassembly
Valve reassembly shall be effected in reverse order to
dismantling.
To maintain functional reliability, new gaskets and gland
packing shall be used whenever the valve is reassembled.
After reassembly and prior to commissioning / start-up, the
valves shall be subjected to a leak test in accordance with
DIN 3230, Part 3l, or API 598 and ASME B16.34 Section 8.
9 Troubleshooting
9.1 General
All repair and service work must be carried out by qualified
personnel using suitable tools and genuine spare parts.
The safety instructions in sections 3 and 8 must be observed.
9.2 Faults & Remedies
Fault - Leakage at the seat
Remedy - Remachine the seat on wedge/disc
and body using suitable regrinding equipment
after dismantling the valve. Regrinding
of body and cone seats should be continued until the seats
show a smooth and even ring.
Fault - Leakage at the cover/bonnet gasket
Remedy - Retighten the cover/bonnet flange connection
Remedy - Replace the gasket (411) after removing the
cover/bonnet bolts (901). Clean the surfaces carefully before
inserting a new gasket.
On asbestos-free gaskets, no additional
sealing agents may be used. When using anti
adhesive coatings, use sealing agents explicitly
recommended by the manufacturer of the sealing material.
If you have any further questions please contact nearest
KSB Sales office.
Fault - Leakage of the Stuffing Box
Remedy - Retighten the stuffing box with the nuts (920) at
the gland flange (452). Make sure that the friction forces at
the stem do not increase too much.
Remedy - Replace the packing rings of the stuffing box;
Unscrew the nuts (920) and lift the gland flange (452). Clean
the stuffing box chamber thoroughly before inserting new
packing rings. Split packing rings should be inserted in such
a way that the slots are offset by 120°to 180°.
Do not replace packing while the valve is
pressurized. The back seat bushing is not intended
to maintain a seal during replacement.
