1 5049/EN/0596/ARevised 06/96DG4V-3S, EN 490 For Mobile EquipmentFlows to 40 l/min ( USgpm), 6* DesignP, A & B Pressures to 350 bar (5000 psi), T Pressures to 210 bar (3000 psi)General DescriptionThis Solenoid Operated directionalcontrol valve is for directing andstopping flow at any point in a hydraulicsystem. Its primary function is todetermine the direction of fluid flow in awork cylinder or control the direction ofrotation of a fluid connections are made by mountingthe valve on a subplate or manifold. Thevalve has wet armature type is derived from the standard modelseries is distinguished as a special by theEN490 designation.

2 Electricalconnections to the valve are typicallymade directly to the Solenoid by variousplug-in devices. Solenoids are availablein DC voltages and Benefits Special design for high tank linerating. Tank line can withstandpressures up to 210 bar (3000 psi).Ideal replacement for DG4V-3 for hightank line pressure applications. Meets key OEM specificationsregarding temperature, vibration, heatrise/drop, impact test, water dunk(thermal shock and hermetic seal),salt spray and dielectric strength test. High thermal shock and impactresistance due to new coil around coil ensures highstrength and allows frame toexpand/contract without added stress.

3 Available with molded-in surgesuppressor/diodes to protect PLCs orcircuit boards from backelectro-magnetic force (EMF). Variety of manual override options areavailable: plain, water-resistant andlatching.
