DG4V-3-2AL-M-U-H7-60 | Eaton Vickers Solenoid Valve 350bar 80L/min

Product Overview

The DG4V-3-2AL-M-U-H7-60, DG4V-3-2AL-VM-U-D6-60, DG4V-3-0A-M-U-H7-60, and DG4V-3-2C-M-P7-H-7-56 are core models in the Eaton Vickers (now Danfoss Power Solutions) DG4V-3 series of direct-acting solenoid directional valves. The DG4V-3 series is Eaton Vickers’ most iconic NG6 size solenoid directional valve product line, with mounting pattern conforming to ISO 4401-03 / CETOP 3 / NFPA D03 standards. The series is renowned for its 350 bar (5,000 psi) high pressure, 80 L/min high flow, and wet-armature solenoid quiet operation technology.

DG4V-3-2AL-M-U-H7-60:

The DG4V-3-2AL-M-U-H7-60 is a 4-way, 2-position solenoid directional valve featuring spring offset configuration. The “AL” suffix denotes Left Hand Build—solenoid and switch locations are reversed compared to standard models. Single solenoid operation—when de-energized, the spool returns to the initial position by spring force. Features 24V DC supply (H7 coil code) with DIN 43650 electrical connector.

DG4V-3-2AL-VM-U-D6-60:

The DG4V-3-2AL-VM-U-D6-60 is also a 4-way, 2-position solenoid directional valve featuring spring offset configuration with Left Hand Build. Key differences from the H7-60 model: the VM suffix denotes Water Resistant Manual Override; the D6 coil code indicates 220/240V AC 50/60Hz supply. This configuration is particularly suitable for demanding wet or dusty environments.

DG4V-3-0A-M-U-H7-60:

The DG4V-3-0A-M-U-H7-60 is a 4-way, 3-position solenoid directional valve featuring Type 0 spool — all ports open in neutral (Open Center) . Features spring offset configuration with single solenoid operation. 24V DC supply. The Type 0 open center allows the pump to unload directly to tank in neutral—ideal for fixed-displacement pump systems for energy savings.

DG4V-3-2C-M-P7-H-7-56:

The DG4V-3-2C-M-P7-H-7-56 is a 4-way, 3-position solenoid directional valve featuring 2C spool type — all ports fully closed in neutral (closed center). Features spring centered configuration with double solenoid operation. 24V DC supply (H7 coil code). The P7 suffix denotes manual override in both end cap and solenoid end (dual override).

The DG4V-3 series features wet-armature solenoid technology—the movable iron core operates fully submerged in hydraulic oil, providing lubrication and cushioning for quiet, long-life, high-reliability operation. The product has passed fatigue life and endurance testing exceeding 20 million cycles.

As original Eaton Vickers DG4V-3 series solenoid directional valves, these products offer complete interchangeability within the same series and size, requiring no modifications to mounting interfaces or piping layouts.

Key Technical Advantages

1. Wet-Armature Solenoid Design for Quiet, Long-Life Operation

The DG4V-3 series features Eaton Vickers’ proven wet-armature solenoid technology—the movable iron core operates fully submerged in hydraulic oil, providing lubrication to reduce wear and cushioning against 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. 350 bar High Pressure and 80 L/min High Flow in Compact NG6 Size

Delivers 350 bar (5,000 psi) peak operating pressure and 80 L/min (21 GPM) flow capacity in a compact NG6 valve body. Tank port allowable back pressure reaches 210 bar (3,000 psi) —placing it at the forefront of directional control valves in its class.

3. Extensive Spool Type and Configuration Options

The DG4V-3 series offers multiple spool types including 0, 2, 3, 6, 8, 31, 33 and spring configurations including spring offset and spring centered. The “AL” Left Hand Build provides flexibility for special layout requirements. “P7” dual manual override provides additional assurance for safety-critical applications. “VM” water-resistant manual override is suitable for wet/dusty environments.

4. Manual Override and IP65 Protection

DG4V-3-2AL-VM-U-D6-60 features Water Resistant Manual Override. DG4V-3-2C-M-P7-H-7-56 features dual manual override (end cap + solenoid end). All models support manual override for emergency directional control during power failure. IP65 protection is achieved with properly installed connector.

5. International Standard Compliance for Global Interchangeability

Mounting conforms to ISO 4401-03 / CETOP 3 / NFPA D03 international standards. The DG4V-3 series offers complete interchangeability with globally adopted NG6 interfaces. The 60 Design Series has been optimized for higher performance and extended service life.

6. Proven Durability and Reliability

The DG4V-3 series has passed fatigue life and endurance testing exceeding 20 million cycles. Optimized spool and bore manufacturing reduces internal leakage, lowers power losses, and increases system efficiency.

• Use 4 M5 mounting bolts—refer to manufacturer specifications for tightening torque.

• 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.

• Left Hand Build (LH) models (2AL) have solenoid and switch locations reversed compared to standard models. Confirm solenoid position matches system wiring orientation during installation.

2. Hydraulic Fluid Cleanliness

• Recommended fluid cleanliness: ISO 4406 19/17/14 or better.

• Compatible fluids: Petroleum-based hydraulic oil. For phosphate ester and other specialty fluids, select Viton (FKM) seal option.

• Operating temperature range: -20°C to +70°C.

• Install a return line filter with minimum 10 μm filtration rating.
