The Eaton MDG mobiledirectional control valve is aversatile and modular designbased upon the proven EatonVickers industry leadingDG4V3 design. The MDGvalve design is a closedcenter, parallel or seriescircuit that can also functionas an open center circuitthrough the use of unloadinginlet options.

The MDG valve offersversatility and flexibility insystem applications througha sectional design, allowingthe use of up to six sectionsper bank assembly. Further, the MDG valve can beconfigured to create custom,multi-functional circuitsthrough the use of optionalbanking functions such asinlet and work port options.

GeneralInformation

Features andBenefits

Modularity

• Sectional design allowsthe use of up to 6sections per bankassembly.

Flexibility and Versatility

• Optional banking functionswith various inlet andwork port options.

Performance andReliability

• Mobile design is basedupon Eaton-Vickersindustry leading DG4V3DG valve.

• Meets key OEMspecifications regardingtemperature, vibration,heat rise/drop, impacttest, water dunk (thermalshock and hermetic seal),salt spray, and dielectricstrength test.

• Modular banking designconcept eliminates costlyfittings and potential leakpoints

ManualOverrides

Water-resistant manual override on solenoid

Model Code Option H10

Application

General use where finger operation is required (standardmanual overrides cannot be operated without using smalltool).

Latching manual override on solenoid

Model Code Option Y10

Application

Stainless steel lever/latch mechanism and water-resistantseal make this feature ideal for vehicle-mounted andexposed applications requiring emergency selection of valvefor a period of time in the event of electrical failure.

Notes:

1. Opposite solenoid (on “C” and “N” double solenoidmodels) should not be energized while the valve is latchedin selected position.

2. “Y” feature is field-convertible from “H” type manualoverride (omitting spacer), but is not field-convertible fromother models.

Fluid Cleanliness

Essential information on thecorrect methods for treatinghydraulic fluid is included inpublication 561 (Guide toSystemic ContaminationControl) and is availablefrom your local Eatondistributor.

Recommendations onfiltration and the selection ofproducts to control fluidcondition are included in 561.

Recommended cleanlinesslevels, using petroleum oilunder common conditions,are based on the highestfluid pressure levels in thesystem. Fluids other thanpetroleum, severe servicecycles, or temperatureextremes are cause foradjustment of thesecleanliness codes. See publication 561 forexact details.
