Technical Specifications Parameter Specification Notes / Interpretation Manufacturer / Series Eaton DG4V D03 / NG6 interface Model Number DG4V-3-2A-M-U-B6-60 Valve Type Directional Control Valve Number of Ways / Positions 4-Way, 3-Position Porting Size D03 (NG6) ISO 4401 standard Port Thread 7/16"-20 UNF Common for D03 size Actuation Type Solenoid Operated, Spring Centered Solenoid Type Single Solenoids (2x) Wet-pin, DC versions Center Position 2A: All Ports Blocked (Closed Center) "A", "B", "P", and "T" are all blocked. Ideal for holding loads. Spool Type -60: Critical Center with Bypass This is a key detail. The "-60" spool provides blocked center functionality for load holding, but includes internal leakage paths for pressure relief during transition, which reduces shock and hammer. Electrical Connection -B6: DIN 43650 Form B IP69K-rated connector, submersible, with manual override. Voltage Options -B6: Typically 12 VDC The "-B6" suffix specifically denotes a 12 VDC coil. Maximum Operating Pressure 350 bar (5,000 psi) Maximum Flow Rate ~ 19 L/min (5 US gpm) Dependent on spool type and pressure drop. Fluid Viscosity Range 10 to 380 cSt (50 to 1800 SUS) Fluid Type Mineral-based hydraulic oils, synthetics Compatible with standard hydraulic fluids. Temperature Range -20°C to +80°C (-4°F to +176°F) For hydraulic fluid. Seal Material Nitrile (NBR) Standard. Other options (e.g., FKM) may be available.
