Right-Angle Valves, Bellows-Sealed,Manually OperatedThese universal valves are ideal especiallyfor smaller systems, where remotecontrol is not essential. They may bealso installed in larger systems, wherebacking pumps or condensate separatorsor similar units are to be cut off atlonger intervals for maintenance purposesby maintenance personnel.Dimension TableDNABCDEISO-K 63 100mm 266 320mm 124 164mm 150 190mm 88 108mm 20 25Advantages to the User- Gentle venting of systems- Seal in both directions up to apressure difference of 1.5 bar- Easy manual operation, for aneffortless vacuum-tight seal- May also be used as a variableleak valve to roughly control gasflows- Installation in any orientation andno restrictions as to the directionof flowDimensional drawing for the right-angle valves,bellows-sealed, manually operatedTechnical Data DN 63 ISO-K DN 100 ISO-KService lifecyclesConductance at molecular flow l x s -1Leak rate mbar x l x s -1Operating pressure rangembarDifferential pressure,closing and opening directionbarOpening against differential pressureat the valve diskbarAmbient / Operating temperature,max. °CSealWeightAluminum bodykgStainless steel bodykgMaterialValve bodyInside sectionLidGaskets> 1.5 mio. > 1.5 mio.140 3301 x 10 -9 1 x 10 -910 -8 - 1500 10 -8 - 15001.5 1.51.5 1.560 60FPMFPM3.6 6.16.5 11.1aluminum alloy (3.2373.63) aluminum alloy (3.2373.63)or stainless steel (1.4305) or stainless steel (1.4305)stainless steel (1.4541/1.4301) stainless steel (1.4541/1.4301)grey cast iron (GG 20) grey cast iron (GG 20)O-rings made of FPMO-rings made of FPMOrdering InformationDN 63 ISO-KDN 100 ISO-KRight-angle valve, bellows-sealed,manually operatedAluminum bodyStainless steel bodySpare partsSeal kitInside sectionPart No. 107 80 Part No. 107 81Part No. 107 83 Part No. 107 84Part No. 215 251 Part No. 215 271Part No. 215 254 Part No. 215 274Oerlikon Leybold Vacuum Full Line Catalog21C14
