DG4V-3-2C-M-U-D6-60 Vickers Solenoid Valve 350bar

Product Overview:

The DG4V series (including specific model codes DG4V-3-2C-M-U-D6-60, DG4V-5-2C-MU-C6-20, and DG4V-3-6C-M-U-D6-60) is a direct-acting solenoid directional control valve engineered strictly to ISO 4401-03 (NG6 / CETOP 03) and ISO 4401-05 (NG10 / CETOP 05) standard mounting interfaces. Designed as a high-reliability aftermarket solution for original Eaton Vickers DG4V valves, this product provides 100% direct drop-in interchangeability. No subplate alterations, mounting adapters, or electrical rewiring are required. Cast from heavy-duty ductile iron and built with micron-honed spools, the DG4V series operates at working pressures up to 350 bar with outstanding volumetric efficiency and ultra-low internal leakage. Every single valve undergoes 100% simulated full-load condition testing before dispatch to guarantee zero-defect field performance.

Technical Specifications:

• Control Method: Direct-acting wet-armature solenoid operated

• Coil Voltage & Connector: 24V DC (D6) / 220V/110V AC (C6) with DIN 43650 (ISO 4400) connectors

• Fluid & Temp Range: Mineral-based hydraulic oils, -20°C to +70°C

• Net Weight: DG4V-3: approx. 2.0 kg; DG4V-5: approx. 4.8 kg (Double solenoid configurations)

Key Technical Advantages:

• 100% Direct Drop-in Interchangeability: Mounting surface geometry, port spacing, and electrical connection profiles strictly align with OEM Eaton Vickers specifications. Field replacement is effortless and instant, eliminating pipeline rework and minimizing machinery downtime.

• Durable Wet-Armature Solenoid Architecture: Features wet-armature solenoids where the moving pin and core operate submerged in system hydraulic oil. This provides continuous self-lubrication, efficient heat dissipation, cushioned switching impacts, and an IP65 protection rating.

• Heavy-Duty Ductile Iron Housing & Precision Honing: Cast from high-grade ductile iron, the heavy-duty housing resists deformation under continuous pressure shocks. Precision compound honing between spool and body bore ensures micron-level clearances, dramatically suppressing internal cross-port bypass at 350 bar.

• 100% Full-Condition Simulation Testing: We reject batch sampling. Every valve is verified on automated test benches under maximum rated pressure (350 bar), full flow rates, and high-frequency switching cycles to eliminate early-life failure or spool binding before delivery.

Application Areas:

• CNC machine tools, cutting platforms, and automated clamping systems

• Plastic injection molding machinery and blow molding auxiliary circuits

• Industrial Hydraulic Power Units (HPUs) and centralized pump stations

• Scrap metal balers, hydraulic shears, and mobile hydraulic machinery

Expert Maintenance Tips:

• Verify Subplate Surface Flatness: Before mounting, inspect the mating subplate surface. Ensure surface flatness is within 0.01/100 mm with a roughness better than Ra 0.8. An uneven surface generates mechanical stress that can bind the internal spool when torqued.

• Enforce Strict Cleanliness Standards: Solid particle contamination is the primary cause of spool scoring and binding. Maintain hydraulic fluid cleanliness to ISO 4406 class 20/18/15 or cleaner using high-efficiency pressure and return filtration.
