BUCHER MONOBLOCK VALVES

Monoblock Directional Valves

Bucher Series HDM

Bucher

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

Available in 4 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 center, parallel/series, closed center and carry-over.

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

Advantages

  • Low weight, small dimensions
  • Operating pressure up to 400 bar (5800 psi)
  • Excellent price/performance ratio
  • Elimination of potential leakage between sections
  • Easy maintenance
