Parameter Specification / Description Manufacturer & Model Eaton DG4V-3-2N-M-U-H7-60 Valve Type Proportional Directional Control Valve (with LVDT feedback) Series / Size DG4V-3 (Size 03) Mounting Interface ISO 4401-03 (CETOP 3, NFPA D03) Port Size (Main) Typically 3/8"-24 UNF, 7/16"-20 UNF, or M18x1.5 Spool Type M – Specific Eaton proportional spool configuration (flow characteristics defined by performance curves). Actuator / Feedback -2N-: Proportional Solenoid with integral LVDT for spool position feedback. Electrical Connector -U-: Multi-pin connector (commonly for power, command signal, and LVDT feedback). Coil / Electronics Version -H7-: High-performance version. Command Signal Typically ±10 VDC or ±20 mA. LVDT Feedback Signal Typically ±10 VDC (representing actual spool position). Supply Voltage (for Electronics) Typically +24 VDC (for valve electronics). Must verify. Maximum Operating Pressure Up to 350 bar (5,000 psi) Rated Flow (ΔP = 35 bar) Approx. 8 - 15 l/min (2.1 - 4.0 US gpm). Consult catalog for exact flow curve of spool "M". Frequency Response (-3 dB, 100% signal) High, typically > 70 Hz (for -H7- version; depends on test conditions). Hysteresis Typically < 1.5% Linearity Typically < ±2.0% Null Bias Typically < 1% of rated signal Required Fluid Cleanliness Critical. Minimum ISO 4406 18/16/13 recommended. For optimum life, ISO 4406 17/15/12 or better. Recommended Fluid Mineral-based hydraulic oils (e.g., ISO VG 32 or 46). Fluid Temperature Range -20°C to +80°C (-4°F to +176°F) for standard seals. Weight (Approx.) ~ 1.8 kg (4.0 lbs)
