Monoblock Directional Valves series HDM25

Pressure [bar]


Flow rate [L/min]


Series HDM directional control valves feature compact, cast monoblock bodies and have high operating pressure ratings.

Available in 9 different sizes, the large range of spools, spool operators, levers and auxiliary shock/anti-cavitation valves make the HDM series especially suitable for use in medium-complexity circuits. They are also very suitable for straight-forward applications in which a particularly small overall size is required.

The HDM series is available in the following versions: open centre, parallel/series, closed centre and carry-over.

A further notable feature is the very low level of internal spool leakage.

  • Low weight, small dimensions
  • Operating pressure up to 350 bar
  • Excellent price/performance ratio
  • Elimination of potential leakage between sections
  • Easy maintenance
  • Fluid temperature: from -20 to + 80°C
  • Viscosity operating range: from 15 to 75 mm²/s (cSt)
  • Max contamination level : 21/19/16 – ISO 4406:1999 (NAS 1638 class 10)
  • Max contamination level for electro-hydraulic applications: 20/18/15 – ISO 4406:1999 (NAS 1638 class 9)
