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 nameSOW-R-46Center bypassSOW-R-46HAll ports openSOW-R-46PP port blockedSOW-R-46CAll ports blockedSOW-R-48Center bypassSOW-R-48HAll ports openSOW-R-48PP port blockedSOW-R-48CAll ports blocked(SOW-R-46/SOW-R-48)● Used for the R46/R48 series solenoid valves and necessary for piping. ■ SpecificationsMaximum operating pressureMPaModelR-46-BP70R-48-BPNo. of portsSize68Series No.No. of solenoidsW:Solenoids on both sides (3 positions)Operating voltage1:100 V2:200 VDC24:24 VDCBlank:Center bypassH:All ports openP:P port blockedC:All ports blockedDirection-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.
