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. 6C Spool Type — Precise Actuator Positioning and Locking
DG4V-3-6C-MU-H7-60 and DG4V-3-6C-M-U-C6-60 feature 6C spool type — all ports P, A, B, and T are fully closed in neutral. This center position ensures the hydraulic actuator is precisely positioned and locked when de-energized, with no position drift due to oil leakage. Ideal for applications requiring strict position holding in neutral.
3. 2A Spool Type — Simple and Reliable Directional Control
DG4V-3-2A-M-U-D6-60 and DG4V-5-2A-M-U-C6-20 feature 2A 4-way, 2-position spring offset configuration. Single solenoid operation with automatic spring return when de-energized. Simple and reliable design for single-solenoid directional control applications requiring automatic return upon de-energization.
4. 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.
5. Proven Durability and Reliability
The DG4V series has passed fatigue life and endurance testing exceeding 20 million cycles. This design achieves higher flow capacity and control precision while maintaining compact dimensions.
6. IP65 Protection and Manual Override
IP65 protection is achieved with properly installed connector. Equipped with push-pin manual override for emergency operation during power failure.

Expert Maintenance Tips
1. Installation Guidelines
DG4V-3 series mounting must conform to ISO 4401-03 / CETOP 3 standards.
DG4V-5 series mounting must conform to ISO 4401-05 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.
2. Hydraulic Fluid Cleanliness
Recommended fluid cleanliness: ISO 4406 19/17/14 or better.
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-U-D6-60 uses 220V 50Hz / 240V 60Hz supply. Verify supply voltage matches coil nameplate voltage before connection.
DG4V-5-2A-M-U-C6-20 uses 220V AC 50Hz supply.
DG4V-3-6C-MU-H7-60 uses 24V DC supplywith power consumption of 30 W.
DG4V-3-6C-M-U-C6-60 uses 220V AC 50Hz supply.
All models feature DIN 43650 / ISO 4400 connectors. Ensure the connector is fully locked to maintain IP65 protection.

4. Manual Override
All models feature push-pin type manual override.
In case of power failure or emergency, the spool can be manually actuated via the push pins.
Manual operation is for emergency use only and is not recommended for continuous duty.
5. Periodic Maintenance Inspection
Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.
Check electrical connectors 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.
Periodically test the manual override function to ensure emergency availability.
