Product Overview

The DG4V-3-6C-M-U-H7-60, DG5V-7-6C-T-M-U-H7-30, and DG5V-7-6C-2-M-U-H7-30 are key models in the Eaton Vickers (now Danfoss Power Solutions) DG series of solenoid-operated directional control valves.

DG4V-3-6C-M-U-H7-60:

The DG4V-3-6C-M-U-H7-60 is an Eaton Vickers DG4V-3 series direct-operated solenoid directional valve, NG6 (Cetop3 / NFPA D03) size, subplate mounting, with mounting surface conforming to ISO 4401-03. This 4-way, 3-position spring-centered valvefeatures Vickers’ proven wet-armature solenoid technology, delivering quiet operation, long service life, and fast response. The valve body features rugged cast iron construction, industrial-grade sealing, and a compact Cetop3 footprint.

As an original Eaton Vickers DG4V-3 series solenoid directional valve, this product offers complete interchangeability within the same series, requiring no modifications to mounting interfaces or piping layouts.

Key Technical Advantages

1. Proven Wet-Armature Solenoid Technology (DG4V-3)
The DG4V-3-6C-M-U-H7-60 features Eaton Vickers’ proven wet-armature solenoid technology, with internal moving parts lubricated by hydraulic oil. Compared to dry-armature designs, the wet-armature configuration delivers lower noise levels, longer service life, and faster response. Solenoid coils can be changed quickly without leakage from the hydraulic system.

2. Two-Stage Pilot-Operated Design (DG5V-7)
The DG5V-7-6C-T-M-U-H7-30 and DG5V-7-6C-2-M-U-H7-30 feature a two-stage configuration with a solenoid pilot valve controlling the main stage spool. The separation of pilot and main stages allows the solenoid to actuate a small pilot spool, which in turn controls the main stage for large flow directional switching—significantly reducing solenoid power consumption while ensuring fast response.

3. High-Pressure High-Flow Performance
The DG4V-3-6C-M-U-H7-60 delivers an exceptional combination of 350 bar operating pressure and 80 L/min flow in a compact NG6 valve body. The DG5V-7 series takes this further with 350 bar operating pressure and 300 L/min flow capacity—placing it at the forefront of directional control valves in its class.

4. Superior Durability and Reliability
The DG4V-3 series is tested and proven for fatigue life and endurance over 20 million cycles. The DG5V-7 series likewise features excellent low-shock characteristics, maximizing machine service life. Rugged cast iron construction with industrial-grade sealing ensures long-term stable operation in diverse demanding environments.

5. Flexible Manual Override Capability
The DG4V-3-6C-M-U-H7-60 is equipped with a manual override (push-pin type). The DG5V-7 series also supports manual override options. In case of power failure or emergency, the spool can be manually actuated for emergency directional control, ensuring system safety.

6. International Standard Compliance and High Installation Compatibility
The DG4V-3-6C-M-U-H7-60 mounting surface conforms to ISO 4401-03 / CETOP 3 / NFPA D03. The DG5V-7 series mounting surface conforms to ISO 4401-07 / CETOP 7. Both are fully compatible with globally adopted interfaces, enabling direct replacement of same-series, same-specification products. The compact design, combined with Eaton SystemStak valves and subplates, enables cost-effective system design.

Expert Maintenance Tips

1. Installation Guidelines

• DG4V-3-6C-M-U-H7-60 mounting surface must conform to ISO 4401-03 / CETOP 3. DG5V-7 series mounting surface must conform to ISO 4401-07 / CETOP 7.

• Thoroughly clean the mounting surface and all ports (P, A, B, T) before installation to prevent foreign particles from entering the valve and causing spool sticking or seal damage.

• Tighten mounting bolts evenly to the specified torque to ensure uniform compression of the sealing gasket between the valve body and mounting surface.

• For DG5V-7 series two-stage valves, pay special attention to correct connection of pilot oil lines (X and Y ports).

2. Hydraulic Fluid Cleanliness

• DG4V-3 series recommended fluid cleanliness: ISO 4406 19/17/14 or better.

• Install a return line filter with minimum 10 μm filtration rating to ensure fluid entering the valve meets cleanliness requirements.

3. Pilot Pressure and Drain Configuration (DG5V-7 Series)

• DG5V-7-6C-T-M-U-H7-30 and DG5V-7-6C-2-M-U-H7-30 feature internal pilot supply and external pilot drain.

• The drain port (Y) must be routed directly to the tank with a pulse-free line, with no back pressure at the drain port.

• Transient pressure must be avoided—any pressure at the drain port adds to the valve pressure setting.

4. Electrical Connection Specifications

• DG4V-3-6C-M-U-H7-30 and DG5V-7 series both use 24V DC supply. Verify supply voltage matches coil rated voltage (20–32 VDC range) before connection.

• Electrical connector is DIN 43650 / ISO 4400 standard. Ensure the connector is fully locked to prevent contact issues caused by vibration—IP65 protection is achieved with properly installed connector.

• Coils feature reverse polarity protection and PNP outputs.

5. Periodic Maintenance Inspection

• DG4V-3 series: 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.

• Solenoid coils can be replaced quickly without disturbing hydraulic connections.

• If response lag or reduced control precision is observed, first check system fluid cleanliness and pilot screens (if applicable) for blockage.
