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0C)orlow(<00C)
temperaturesmusteitherbetted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.

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 (refer clause 6.6, Execution ref. PR-01 to
PR-06)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.
Forged Steel Globe Valves in High Pressure /
Temperature Drain Service
InStart-upVent/Drainapplication,theGlobevalvesarelikely
toaccumulateforeignparticleslikescaleorrust.During‘‘rush’’
oftheflow,theseparticlesmayerodeSealingSurfacesonDisc
andBodySeat,whentheflowis‘‘BelowtheDisc’’.
KSB’s‘‘Y’’typeGlobeValvescanbeinstalledindividuallyorin
tandem for improved life time of valves in the high differential
drainservicewithgoodshutofffunction,with‘‘Flowoverthe
Disc’’orientation.
Insuchstart-up/ventanddrainapplications,werecommended
‘‘FlowovertheDisc’’forfollowingreasons:
- minimalSeaterosionduetooccasionallyflowingsediment/
foreign particles
- usingthedifferentialpressure,actingontopsideoftheDisc,
to assist effective sealing
- minimizingloads/stressintheStem
Thisorientationofthevalvei.e.‘‘FlowovertheDisc’’willserve
thesepurposeandthelifecycletimeofGlobeValvesmaybe
extended.
6.2.3 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.
Checkvalvesareprovidedwithtwoextralongstuds(902)or
atappedholeinthecover(refersketchSCC150-600)which
serves a means of lifting lugs.

If a swing check valve and a gate valve with pressure seal
bonnet (166) are connected in series over a short distance
thenthemediumtrappedwhenthevalveisclosedcancause
a pressure rise at the pressure seal bonnet and the closing
element.Theusermusttabodysafetydevice/valveonthe
pipe line to protect the Check valve body from being over
pressurizedduetoentrappedfluidbetweenclosedelements
ofGate&Checkvalve.Ifthereisanydoubtdonothesitateto
contactKSB.
6.4 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thevalveintothepipeline,take
special precautions, i.e. welding in several
steps, to that the temperature in the middle of
thebodydoesnotexceedthemaximumpermissibleoperating
temperature.Duringtheweldingprocess,Gate/Globevalves
must be kept in open position. Follow the guidelines from
applicablecodesforweldingprocedure/postweldprocedures.
Do not attach the welding cables (opposite
pole) to the moveable parts of the valve,
otherwisethesepartsmaybescorched.
6.5 Actuated valves
Electricalcablesmayonlybeconnectedbyqualied
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.
6.6 Body safety arrangement (pressure relief)
Heat buildup of trapped liquid volumes is a
phenomenonwhichmainlyaffectsgatevalves.
Ifthereareliquidresidueinthevalvebodyafterthehydrostatic
pressure test, for instance, or condensate has collected in the
valve body due to a particular operating condition, there is a
riskofanimpermissiblepressurerisewhenthebodyisheated
upbyhotwaterorsteaminoneorbothoftheadjoiningpipes.

Gatevalveswithpressuresealthereforehavetobeequipped
withabodysafetyarrangementwheneverthereisariskof
trapped liquid volumes heating up. This prevents excessive
loads on the valve body and potential deformation under all
operating conditions and thus ensures safety.
This aspect has been addressed in ASME B16.34 which
says……
ASME B 16.34 Cl 2.3.3 – Fluid Thermal Expansion. “…..
A certain circumstance in which the center cavity is lled
or partially lled with liquid and subjected to an increase in
temperaturecanresultinanexcessivebuildupofpressurein
the center cavity that may lead to pressure boundary failure. An
exampleisapipingsysteminwhichliquidfromthecondensing,
cleaning, or testing fluids accumulates in the center cavity of a
closedvalve.Suchaccumulationmayresultfromleakagepast

procedure to ensure that the pressure in the valve will not
exceedthatallowedbythisstandardforattainedtemperature.
In the view of above KSB has standardized pressure relief
arrangementbywayofdrilledholeontheupstreamsidedisc
intheabsenceofcustomerspecication.However,thismakes
theValveUni-Directional.
The potential pressure rise depends on the
temperature and the degree to which the body is
lledandmayrapidlyreachunallowablevaluesfor
the body.
The problem of heat buildup of trapped liquid volumes is
particularly dangerous when the gate valve is tted with a
pressureseal,asthecoversealwillbecomeeventighteras
the pressure rise.
Ongatevalvewithflangedcovers,unallowablepressurerises
arerelievedthroughleaksdevelopingatthecovergaskets.

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.
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.
Largesizecheckvalves>12”inlowflow,low
pressureandfluctuatingflowconditionsmay
causechatteringofdiscwithseat.KSBrecommendsuseof
appropriate means of balancing of disc.
7.1.2 Operation
Thevalvesareclosedbyturningthehandwheelintheclockwise
direction (top view) and opened in the counterclockwise
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rsttime.
If necessary, retighten the nuts (920.2) at the gland flange
(452)evenly.
On valves in pressure seal design, the nuts (920.1) of stud
(902.1) which hold the bonnet (139) and the gaskets (411)
under tension must be tightened so as to prevent leakage,
duetothebonnet(139)sinkingintothebody(100)whenthe
pressure drops.
The cover flange connection (902.1/920.1) and the gasket
(411)shouldbecheckedfortightnessaftertherst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 920.1 to prevent
jammingoftheseat.
Retighteningofthenuts(920.1)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cannotbe
assured.

Forsettingofactuator,pleasereferinstructionmanualwhich
willbekeptinthewiringsidecompartment/coverofactuator.
Duringsettingensuretorquesettingforopenpositionmustbe
10%morethanclosedposition.
7.2 Decommissioning
During extended shutdowns periods, liquids liable to
change their condition due to polymerization, crystallization,
solidication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qualiedpersonnel.
Forallmaintenanceand repair work, the safetyinstructions
listedbelowandalsothegeneralnotesinsection3mustbe
