RADIATOR VALVESLOCKSHIELD6DescriptionLockshields Series 193R, 194R, 1193R,1194R, are used as shut-off and controldevices for heat emitters (radiators, fan coilconvectors, radiant panels, etc.) in heatingand air-conditioning systems.The lockshields are available in the configurationwith straight or angle body, with male orfemale thread.Connection to the heat emitter is via a straighttailpiece, with the aid of a spanner, thusensuring better mechanical tightness for theradiator connection. Water tightness isensured by traditional sealing with hemp.ApplicationAlthough the lockshields are not true settingdevices, they can also be used for hydraulicbalancing of the heat emitters by adjusting theplug stroke using a 6 mm Allen key.Micrometric lockshield with angle body female threadfor iron pipes.Type Part No. Dn Heat emitter Dn pipe Kvs Weight (g)193R 193SN38R 3/8” 3/8” 1.8 130193R 193SN12R 1/2” 1/2” 1.9 150Micrometric lockshield straight body female threadfor iron pipes.OperationValve operation takes place through themanual movement of the plug which shuts offthe heat carrier fluid. The plug is provided witha soft seal (O-ring) for improved hydraulictightness.For the hydraulic flow rate and pressure drops,see relative charts.To adjust the lockshield, remove the cap andturn the plug using a 6 mm Allen key.Type Part No. Dn Heat emitter Dn pipe Kvs Weight (g)194R 194SN38R 3/8” 3/8” 1.2 150194R 194SN12R 1/2” 1/2” 1.4 200Micrometric lockshield with angle body male threadfor copper/ polyethylene pipes.The setting positions are according to thenumbers of turns in opening of the lockshieldstarting from fully closed position (See table).The reliability of lockshields Series 193R,194R, 1193R, 1194R, is ensured thanks tothe 100% testing of the production whichchecks the hydraulic sealing properties of thevalve body and its components towards theoutside and that of the plug in its flow shut-offfunction.Type Part No. Dn Heat emitter Dn pipe Kvs Weight (g)1193R 1193SN38XR 3/8” 1/2” 1.8 1301193R 1193SN12R 1/2” 1/2” 1.9 150Micrometric lockshield straight body male threadfor copper/polyethylene pipes.InstallationSelection of the valves and lockshiedsdepends on the size of the connection to theradiator and the connecting pipe.Lockshields Series 193R, 194R, 1193R,1194R can be installed on heat emitterssupplied by iron, copper and plastic piping.Type Part No. Dn Heat emitter Dn pipe Kvs Weight (g)1194R 1194SN38XR 3/8” 1/2” 1.2 1501194R 1194SN12R 1/2” 1/2” 1.4 200
