EDG Overview


18

DC-CH - EDG compact/flexible pre-compensated directional valveComing from our strong experience/know-how on EDC Flow Sharing direct acting valve, we have now been developing a more compact and configurable pre-compensated valve. The new EDG with electrohydraulic actuation is a new technology evolution with interesting improvements (respect to main competitors)

EH Actuation 60 LPM 350 bar working pressure 14mm main spool diameter 12mm compensator diam Spool sensor option

Direct Actuation 40 LPM 350 bar working pressure 12mm main spool diameter 12mm compensator diam Spool sensor option

Compact /low weight and highly configurable solution. Auxiliary valve integrated in the housing for direct acting and piloted version.

Suitable for different application AWP FKL TMC MUC AG

Same interface for EH and DA (Direct Acting) versions.

EH version: more compact housing with integrated auxiliary valves, cast iron version better ∆p performance for internal channels; no need for plugs (Compared to Main Competitor Solution)

Special Medium Body version with integrated Counterbalance valve for Forklift application

Interface plate for existing valve from ED line
