Technical Analysis of Vickers Hydraulic Valve DG4V-5-22AJ-M-U-H7-29-EN124

1. Product Overview

• Model: DG4V-5-22AJ-M-U-H7-29-EN124

• Manufacturer: Vickers (a brand under Eaton, a leading global supplier of hydraulic components)

• Type: Solenoid-Operated Directional Control Valve

• Function: Used in hydraulic systems to control the flow direction, pressure, or flow rate of hydraulic fluid, enabling the activation, deactivation, or direction reversal of actuators (e.g., cylinders, motors).

2. Model Code Breakdown

Vickers' DG4V series model codes contain key technical specifications, dissected as follows:

【表格】

Code Segment Meaning

DG4V Series Identifier: D = Directional Control Valve, G = Solenoid-Operated, 4V = 4-Way Spool Valve Design.

-5 Spool Size: 5 indicates the spool specification (affects flow capacity).

-22AJ Coil & Voltage: 22 denotes a 24VDC coil; AJ signifies special seals or coatings (corrosion/wear-resistant).

-M Mounting Style: M indicates pipe-mounted (other options include subplate-mounted).

-U Spring Return: U denotes dual-spring center return (default neutral position).

-H7 Seal Material: H7 indicates fluorocarbon rubber (FKM) seals, resistant to high temperatures and chemicals.

-29 Spool Neutral Function: 29 represents "H" type neutral function (all ports open, cylinder floating).

-EN124 Special Certification or Standard: EN124 may refer to a European standard number (specific application to be confirmed).

3. Key Technical Parameters

• Operating Pressure: Typically 350 bar (refer to specific product manual; may vary slightly by model).

• Flow Capacity: Depends on spool size (-5) and pressure differential; maximum flow ~100 L/min (subject to verification).

• Voltage: 24VDC (confirmed by coil identifier 22AJ).

• Neutral Function: H-type (all ports open, cylinder ends connected to tank; suitable for floating or unloading scenarios).

• Seal Material: Fluorocarbon rubber (FKM), suitable for high temperatures (up to 200°C) and chemically corrosive media.

4. Applications

• Construction Machinery: Hydraulic systems in excavators, cranes, requiring frequent direction changes and high seal reliability.

• Industrial Equipment: Injection molding machines, die-casting machines, demanding precise directional control.

• Special Environments:

• Hydraulic systems with corrosive media (fluorocarbon rubber seals).

• Applications requiring cylinder floating (e.g., platform leveling, clamp release).

5. Advantages & Features

• High Reliability: The Vickers brand is renowned for durability and stability in heavy-duty industrial environments.

• Modular Design: Integrates with other Vickers valves or components, simplifying system design.

• Corrosion-Resistant Seals: Fluorocarbon rubber (FKM) extends valve lifespan in harsh environments.

• Standardized Interfaces: Pipe-mounted (M) for easy installation and maintenance.

6. Precautions

• Compatibility Verification: Confirm system voltage (24VDC), fluid cleanliness (recommended ISO 18/16), and temperature range (-20°C to +200°C).

• Neutral Function Selection: H-type may cause cylinder drift; adjust based on load stability requirements.

• Certification Requirements: If EN124 refers to a specific industry standard (e.g., European Machinery Directive), ensure valve compliance.

7. Alternative Models & Selection Recommendations

• Alternative Model: For higher flow, consider the DG4V-7 series (spool size -7).

• Selection Recommendations:

• Prioritize fluorocarbon rubber (FKM) seal models (e.g., H7) for high-temperature or chemical applications.

• For subplate mounting, select -B suffix models (e.g., DG4V-5-22AJ-B-U-H7-29).
