1 Vickers Directional Controls Solenoid Operated Directional Valve DGV-3S, EN 90 For Mobile Equipment Flows to 0 l/min (10.5 USgpm), * Design P, A & B Pressures to 350 bar (5000 psi), T Pressures to 10 bar (3000 psi) Variety of manual override options are available: plain, water-resistant and latching. High performance features including minimal pressure drop, scratch-proof override seals, high reliability, multiple electrical connections and ease of servicing. Characteristics Maximum Operating Pressure A, B and P ports: 350 Bar (5000 psi) Maximum Tank Line Pressure 10 bar (3000 psi) General Description This solenoid operated directional control valve is for directing and stopping flow at any point in a hydraulic system. Its primary function is to determine the direction of fluid flow in a work cylinder or control the direction of rotation of a fluid motor. Port connections are made by mounting the valve on a subplate or manifold. The valve has wet armature type solenoids. It is derived from the standard model series DGV-3S-0. It is distinguished as a special by the EN90 designation. Electrical connections to the valve are typically made directly to the solenoid by various plug-in devices. Solenoids are available in DC voltages only. Features and Benefits Special design for high tank line rating. Tank line can withstand pressures up to 10 bar (3000 psi). Ideal replacement for DGV-3 for high tank line pressure applications. Meets key OEM specifications regarding temperature, vibration, heat rise/drop, impact test, water dunk (thermal shock and hermetic seal), salt spray and dielectric strength test. High thermal shock and impact resistance due to new coil design. Frame around coil ensures high strength and allows frame to expand/contract without added stress. Available with molded-in surge suppressor/diodes to protect PLCs or circuit boards from back electro-magnetic force (EMF).

Latching manual override on solenoid DGV-3S-****(L)-Y-(V)M-**-**-0-EN90 Application Stainless steel lever/latch mechanism and water-resistant seal make this feature ideal for vehicle-mounted and exposed applications requiring emergency selection of valve for a period of time in the event of electrical failure. Manual actuation must be applied within this diameter: approximately 0 (0.75). Spacer prevents actuation by larger device. 15 (0.)

9 Surge Suppression Devices (For DC Valves) Standard diode (D) Diode in parallel with coil. When switch (S 1 ) is opened, the energy stored in the coil is trapped and dissipated by the diode (D ). Works only with DC voltage Polarity dependent Increases drop out time D S 1 NOTE: These surge suppression devices are Polarity Dependent. Proper biasing conditions must be met when installing/connecting a coil in a system. Valve Shift and Dropout Times With and Without Surge Suppression Shift Dropout CETOP 3 No Diode 3 0 Diode 3 11 Times represent cessation/application of voltage to coil versus velocity (start/stop) of a cylinder using a single solenoid, spring offset valve (time in milliseconds).

The required bolt length should allow 0.0 (10 mm) thread engagement in the subplate/manifold block. Bolts should be torqued to 57 N.m ( lbf. in.) with threads lubricated. Prior to installation of DGV-3S valve, ensure that both the face of the valve and the face on which it is being mounted (i.e subplate, manifold, SystemStak valve or plate) is as clean as possible. Do not over tighten hold-down bolts beyond recommended values. 10

11 Mounting Interface The minimum thread depth is 1.5 times bolt diameter. The recommended full thread depth is x D+mm to aid interchangeability of valves and to reduce the number of mounting bolt lengths. The recommended engagement of the mounting bolt thread for ferrous mounting is 1.5 x D. Mounting surface must be flat within 0.013mm (.0005) and smooth within 1.1 micrometer (5 microinch). Mounting bolts when provided by customer should be grade 1.9 (SAE grade 7) or better. Dimensions shown in millimeters (inches). **The dimensions specifying the area within the dotted lines are the minimum dimensions for the mounting surface. The corners of the rectangle may be radiused as shown. Fluid Cleanliness Essential information on the correct methods for treating hydraulic fluid is included in Vickers publication 51 Vickers Guide to Systemic Contamination Control available from your local Vickers distributor or by contacting Vickers, Incorporated. Recommendations on filtration and the selection of products to control fluid condition are included in 51. Recommended cleanliness levels, using petroleum oil under common conditions, are based on the highest fluid pressure levels in the system. Fluids other than petroleum, severe service cycles, or temperature extremes are cause for adjustment of these cleanliness codes. See Vickers publication 51 for exact details.
