General Information:
•Toprovideanoptimumservicelife,thevalveshouldbeoperatedonlyinitsfully
openorfullycloseposition.Ifthevalveisusedinpartlyopen(throttled)
position,seatlifemaybereduced.
•Extendingthehandleleverisconsideredmisuseandcandamagethevalveor
causeinjuries.
•Thevalvebodyratingcanbehigherthantheseatrating.
•Highviscousorabrasivemedia,frequentoperationandtemperature
fluctuationscouldcauseanincreaseinvalvetorque.
•Valvepressurevariesunderdifferentmodels,sizes,workingtemperaturesand
materials.Pleaseverifytheapplicationwithinthelimitsspecifiedhereinandas
describedonmetalplatespotweldedonvalvebody.Referencescontainedin
thisdocumentstothe‘PED”areinregardstoEuropeanPressureEquipment
Directive97/23EC.
•AlwaysuseTruelinerecommendedsparepartsformaintenanceand
replacement.
Shipping and Storage:
Allvalvesarepackedinstrongcardboardsandplasticbagstoavoidanypossible
damageduringtransportation.Allthevalvesmustbeexaminedonreception,toensure
thattheyhavenotsufferedanydamagesduringtransport,andthesuppliermustbe
informedofanydamagesobserved.Iftheitemsarenotforimmediateuse,please
followthefollowinginstructions:
1. Leavethevalvesinfullyopenposition.Neverleavethevalveinapartiallyopen
position.
2. Alwayskeeptheprotectivecoversinplaceuntilthevalveisreadyfor
installation.
3. Thevalvesshouldnotbeunpackeduntiltheyaretobedefinitivelyinstalled,
exceptforpurposeofinspection.Afterinspectiontheywillbepackedagain.
4. Thevalvesshouldbestoredundercoverandprotectedfromsevereweather
conditionsandforeignbodies.
5. Stainlesssteelballvalvesdonotneedanyadditionalprotectioncoatingsonce
theyareinstalled.
6. ValvestobestoredforalongperiodoftimeshouldbeinspectedbyQC
personneleverysixmonthsandeverythreemonthsforautomatedvalves.

General Installation Step:
Thehandlingandtransportingofthevalvesmustbecarriedoutwithextreme
precautionandusingthenecessary&adequatemeansonthebasisoftheirsizeand
weight,avoidinganyriskstothepersonthathandlethem.
1. Valvepressurevariesunderdifferentvalveseries,sizes,applicationtemperature
andthematerialofthemainparts.Pleaseverifytheapplicationwithinthelimits
andasdescribedonthevalvebody.
2. Priortoinstallation,pleasemakesurethevalveisfreefromdirtandother
foreignmaterialsthatcoulddamagethevalveseats,asthesepartsare
fundamentaltothecorrectoperationofthevalve.
3. Itmightbenecessarytoflushtheballvalve,valvecavityandthepipestoremove
theaccumulateddirtandburrs.
4. Valvesshouldbeoperatedforatleasttwocompletecyclesbeforethe
installationtothepipe.Allthemultiportballvalveshaveavisualindicator
engravedonthevalvestem.Makesurethevalveportconfigurationcomplywith
theflowarrangementofthepipe.
5. Useanypipesealantsuitableforthematerialandtheprocessthatthevalveis
installedin.Don’tusethesealanttooexcessivelytoavoidtheobstructionin
valveoperation.
6. Alwaysleaktestthesystembeforeusing.
Installation Step for Screwed End:
1. Keepthevalveinopenposition.
2. Checkthevalvethreadsandthethreadsoftheconnectingpipeandmakesure
thesearefreefromdirt,gritorburrs.
3. Useananti‐seizethreadsealanttosealandpreventgalling.Taperthreaded
fittingsshouldnotbeovertightened.
4. Whentighteningvalve,useawrenchontheendnearesttothepipe.
Installation Step for SW/BW End:
1. Tackweldthevalve(inopenposition)endcapstothepipesatthreepoints.
2. Loosen&separatetheendcapsfromthebody.Removetheseatandsealand
setasideinthecleanandsecuredareaforreassemblylater.
3. Weldcompletelytheendcapstothepipes.Allowenoughtimeforcoolingthe
weldedjoints.Removetheremnantfromtheendcapsandpipes.
4. Putbacktheseatsandreassembletheendcapstothebodyaccordingtothe
BoltTorqueSpecifications.

Preventive Maintenance:
Preventivemaintenanceoperationsessentiallyconsistofperiodicinspectionsto
ensurethatthevalveisworkingproperly.

1. Thevalvemustbeopenedandclosedatleastonceeverysixmonths.Theuser
willberesponsibleforestablishingopeningandclosingplansthatareadequate
fortheworkingconditionsandfluidsused.
2. Beforemakingthemaintenance,alwaysmakesurethepressureisreleasedand
thelinehasbeenclosed.
3. Wearprotectiveclothingadequateforthecirculatingfluid.(Complywiththe
safetyguidelineslaiddownbythecompany).
4. Ifleakagehappensatthestem,tightenthestemnutaquarterturnasaroutine
maintenanceprocedure.Thiswillcompensateforanywearingorsettlingofthe
glandpacking.
5. Don’tovertightenthestemnut.Itwillcauseinexcessiveoperatingtorqueand
shortenthelifeofthepackingservice.Ifleakagepersists,depressurizethevalve
andreplacethestempacking.
6. Ifleakageisdetectedinthebodyseal,tightenthebodyconnectorbolts.Ifthe
leakagestilloccurs,thiswillbeduetothedamagedseal.Thevalveneedstobe
dismantledforrepairs.
Disassembly:
1. Makesuretheinstallationisnotunderpressure.
2. Loosenallbodyboltsorscrewsandremovethebodyfromtheline.Ifthe
circulatingfluidisnoxiousorinflammableprecautionsmustbetakentoavoid
accidents.
3. Removeanddiscardtheseatsandbodyseals.Removetheballandcheckthe
exteriorsurfaceoftheball,particularlytheareaincontactwiththeseatandthe
radiusortransitionbetweentheexteriorsurfaceandthebore.Iftheball’s
surfaceisdamagedreplaceitwithanewone.
4. Removethehandlesubassembly(handlenut,handle,stemnut,tabwasher,and
glandbushing).Placeallcomponentsincleanandsecuredarea.
5. Pushdownthestemintostuffingboxanddiscardthestempacking,O‐Ring,
thrustwasher.Becarefulnottoscratchornickthestempackingareaofthe
stuffingboxarea.
