BUCHER 200061123043 HDM11S/2K03 150/A01A01 Control block
BRAND : BUCHER
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.
