If ordering the solenoid valve only, please purchase them separately. (The connection joints are included with a sub-plate.) * For the SOW-R-46 series, use 8 hexagon socket head bolts (M10 × 30). For the SOW-R-48 series, use 12 hexagon socket head bolts (M14 × 45). * For the solenoid specifications, see page 223. ■SOW-R-46ModelHydraulic symbol nameCenter bypassAll ports openP port blockedAll ports blockedCenter bypassAll ports openP port blockedAll ports blockedSOW-R-46SOW-R-46HSOW-R-46PSOW-R-46CSOW-R-48SOW-R-48HSOW-R-48PSOW-R-48C■Hydraulic symbol(SOW-R-46/SOW-R-48)Maximum operating pressureModelMPaR-46-BP70R-48-BP■SOW-R-46Maximum operating pressureMPa70■Hydraulic symbol(SOW-R-46H/SOW-R-48H)Connection port size RcApprox. weightA/B/P/T3/4Maximum flow rateL/min0 to 6 Mpa6 to 70 Mpa50169030■Hydraulic symbol(SOW-R-46P/SOW-R-48P)PLkgMounting bolts: M10 x 100 (4 pcs) 173/8Mounting bolts: M12 x 120 (4 pcs)31No. of solenoidsW:Solenoids on both sides (3 positions)■SOW-R-48Allowable back Pilot pressure pressureMParangeMPa1 to 7■Hydraulic symbol(SOW-R-46C/SOW-R-48C)AccessoryConnection joints (3 pcs) O-ring: P16 (1 pc)O-ring: P18 (2 pcs)Connection joints (3 pcs) O-rings:P16 (1 pc)P21 (2 pcs)No. of portsSizeSeries No.Operating voltageApprox. weightkg15.3100 VAC200 VAC24 VDC27.0Compatible valveNotesSOW-R-46For piping SOW-R-48Operating voltage1:100 V2:200 VDC24:24 VDCBlank:Center bypassH:All ports openP:P port blockedC:All ports blockedDirection-Control ValvesR46/R48 Series (4-Way Spool-Type Solenoid Operated Direction-Control Valves)*When mounting a R46/R48 series solenoid valve on a pump or when using a large-size modular valve such as a pilot controlled check valve, see pages 156 to 159. * For the external drawings of the sub-plates, see page 120.
