Parameter Description / Value Notes Product Line Eaton DG4V Second Generation Valve Type Single-Stage Proportional Directional Valve 4-way, 3-position Porting Size NG05 (CETOP 5 / NFPA D02) Maximum Operating Pressure 350 bar (5,075 psi) Maximum Flow Rate Approx. 40 - 60 L/min (10.5 - 16 US gpm) Note: Actual flow depends on spool and pressure drop. Spool Type 22AJ "22" typically denotes a high-performance spool series with LVDT, and "AJ" is the specific spool metering characteristic. Center Position M (Closed Center / All Ports Blocked) In the center (neutral) position, all work ports (A, B) and the pressure port (P) are blocked, and the tank port (T) is open. This holds an actuator in place. Solenoid Type Proportional Solenoid Wet armature design. Feedback Type Integrated LVDT The spool has a built-in LVDT for closed-loop position control. (This is implied by the "22" series and the H6 amplifier). Electrical Connector U (DIN 43650 Form A, 4-pin) Standard industrial connector. Integrated Electronics H6 On-board amplifier card designed for LVDT feedback valves. Input Signal ±10 VDC or 4-20 mA Selectable via internal dip-switches. Supply Voltage (to amplifier) 12-30 VDC For the H6 amplifier. IP Rating IP65 (with connector properly installed) Dust-tight and protected against water jets. Hydraulic Fluid Mineral-based hydraulic oil to ISO 11158 Fluid Viscosity Range 10 to 400 cSt (50 to 2000 SUS) Operating Temperature Range -20°C to +70°C (-4°F to +158°F)
