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.

Advantages

Low weight, small dimensionsOperating pressure up to 350 barExcellent price/performance ratioElimination of potential leakage between sectionsEasy maintenance
