Standard DSG-03
Choose the spool, spring arrangement and electrical configuration using the model designation table. AC coil ratings also depend on supply frequency.
Yuken solenoid operated directional valves
DSG-03 Series directional valves
Compare standard and shockless 3/8 directional valves, then confirm the spool function, coil and mounting details for your requirement.

Select the switching arrangement
The DSG-03 Series uses a solenoid to change the directional-valve spool position. The range includes spring-centred, spring-offset and no-spring detented arrangements.
Standard DSG-03 and shockless S-DSG-03 configurations have different ratings and coil choices. Check the circuit symbol against the required actuator movement and neutral condition before selecting a model.
Standard and shockless specifications
| Catalogue rating | DSG-03 standard | S-DSG-03 shockless |
|---|---|---|
| Maximum flow ceiling | 120 L/min | 120 L/min |
| Maximum operating pressure | 315 Kgf/cm²; spool type 60: 250 Kgf/cm² | 250 Kgf/cm² |
| Maximum T-line back pressure | 160 Kgf/cm² | 160 Kgf/cm² |
| Maximum changeover frequency | 240 Cycles/Min.; R type solenoid: 120 Cycles/Min. | 120 Cycles/Min. |
| Coil families | AC, DC and R type rectified | DC and R type rectified |
These are catalogue limits, not ratings for every spool combination. Permissible flow depends on spool function, pressure, flow path and solenoid supply. Review the flow tables and centre bypass limits in the catalogue.
Shockless S-DSG-03
The shockless variant is intended to reduce switching noise and pipe vibration. Direct AC solenoids are not listed for this variant; consult the R type rectified options for an AC supply.
Mounting and connection options
Confirm the mounting face and port threads against your manifold or sub-plate drawing.
| Sub-plate model | Thread size |
|---|---|
| DSGM-03-2180 | 3/8 BSP.F |
| DSGM-03X-2180 | 1/2 BSP.F |
| DSGM-03Y-2180 | 3/4 BSP.F |
Electrical connection codes include N0 without connector, N with plug-in connector and N1 with an indicator-light connector. Confirm the complete code and required accessories when enquiring.
