Key Technical Advantages
1. Wet-Armature Solenoid Design for Quiet, Long-Life Operation
The DG4V series features Eaton Vickers’ proven wet-armature solenoid technology—the movable iron core operates fully submerged in hydraulic oil. The hydraulic oil lubricates moving parts to reduce wear and cushions switching impact and vibration. Compared to dry-armature designs, the wet-type configuration delivers lower noise, longer service life, and higher reliability. Coils can be changed quickly and easily without leakage from the hydraulic system.
2. Efficient Control of Greater Hydraulic Powers
The DG4V series 60-design has been specially optimized to control greater hydraulic powers without increasing solenoid power consumption. This design achieves higher flow capacity and control precision while maintaining compact dimensions.
3. International Standard Compliance for Global Interchangeability
Mounting conforms to ISO 4401 international standards. The DG4V series offers complete interchangeability with Rexroth, Parker, Atos, Yuken, and other major brands. Compact design with Eaton SystemStak valves and subplates enables cost-effective system design.
4. Multi-Fluid Capability Without Seal Changes
The DG4V series features multi-fluid capability without the need to change seals for different hydraulic media. The DG4V-5-2A-M-U-C6-20 features Viton seals for superior heat and chemical resistance.
5. Multiple Voltage and Configuration Options
The DG4V series covers multiple voltage options including 24V DC, 220V AC, 230V AC, with DIN 43650, flying lead wiring housing, and other electrical connection options. The EN608 suffix model features a 1/2 inch NPT threaded wiring housing with flying leads for convenient field wiring and maintenance.
6. IP65 Protection for Demanding Environments
IP65 protection is achieved with properly installed connector, effectively resisting dust and water ingress. The DG4V-3-2A-M-FTWL-D7-HL7-60-EN608 features response time of just 28–45 ms for fast and precise directional control.

Expert Maintenance Tips
1. Installation Guidelines
DG4V-3 series mounting must conform to ISO 4401 Size 03 / CETOP 3 / NFPA D03 standards.
DG4V-5 series mounting must conform to ISO 4401-05 / CETOP 5 standards.
Thoroughly clean the mounting surface and all ports (P, A, B, T) before installation to prevent foreign particles from entering and causing spool sticking or seal damage.
Tighten mounting bolts evenly to the specified torque to ensure proper sealing between the valve body and mounting surface.

Fluid temperature range: -20°C to +70°C.
Install a return line filter with minimum 10 μm filtration rating.
3. Electrical Connection Specifications
DG4V-3-2A-M-FTWL-D7-HL7-60-EN608 uses 24V DC supply. Verify supply voltage matches coil nameplate voltage before connection.

4. Manual Override
5. Periodic Maintenance Inspection
Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.
Check electrical connectors/wiring housings for looseness, oxidation, or moisture ingress.
Wet-armature solenoid coils can be replaced quickly without disturbing hydraulic connections.
If response lag or unstable shifting is observed, first check system fluid cleanliness and verify the spool is not sticking.
