Product details
I. Product Overview
• Brand and Model: This solenoid directional control valve belongs to the VICKERS brand, with the model number DG4V-3-0B-M-U-H7-69-EN124.
• Origin: United States (some products may be manufactured in China or other regions, but the brand and technology originate from the United States).
• Application Areas: Widely used in industrial automation, machinery manufacturing, construction machinery, agricultural machinery, shipbuilding, and port machinery.
II. Product Features
1. Structure and Design:
• Valve Body and Spool: Made of high-quality alloy steel valve body and wear-resistant spool, combining pressure and corrosion resistance, suitable for heavy-duty and high-frequency operations.
• Three-Position, Four-Way Design: The core features a three-position, four-way spool design, enabling the switching and flow control of hydraulic oil in multiple pathways to meet the complex action requirements of hydraulic systems.
• Sealing Performance: The sealing materials are polymers with excellent high-temperature and oil-resistant properties, effectively preventing leakage and extending system life.
2. Performance Parameters:
• Rated Pressure: 250 bar (some sources mention 350 bar, depending on the application scenario and configuration), adapting to high-pressure working conditions and enhancing equipment stability.
• Flow Capacity: Up to 100 L/min (some sources mention 80 L/min, depending on the model and configuration), suitable for high-flow hydraulic systems.
• Response Time: The switching time is generally less than 20 milliseconds, improving the sensitivity of equipment response.
• Electrical Connection: Supports multiple voltage specifications, such as 24 VDC, facilitating compatibility with different control systems. The electrical connection complies with the ISO 4400 (DIN 43650) standard.
3. Durability and Stability:
• Durability: Exhibits outstanding durability and stability, reducing maintenance frequency and operational failures, and lowering the risk of equipment downtime.
• Adaptability: Capable of adapting to harsh working conditions, such as high pressure, high flow, and high-frequency switching.
III. Application Scenarios
1. Construction Machinery: Provides precise control of hydraulic actions, enabling smooth movement of the arms and buckets of excavators and loaders.
2. Automation Equipment: Offers efficient hydraulic switching solutions, ensuring fast and accurate operations in production lines.
3. Agricultural Machinery: Resistant to mud and harsh environments, adapting to the variable working conditions in farmland.
4. Shipbuilding and Port Machinery: The high-pressure and high-flow characteristics support heavy-duty operations with high safety requirements.
IV. Maintenance and Upkeep
1. Regular Inspection: Regularly inspect the quality of hydraulic oil and its replacement cycle to prevent impurities from entering the valve body and causing wear.
2. Cleaning and Maintenance: Keep the solenoid coil and connection terminals clean to avoid short circuits and poor contact.
3. Temperature Monitoring: Monitor the valve body temperature according to actual working conditions to avoid prolonged overload operation.
4. Fault Handling: In case of abnormal noise or sluggish movement, stop the machine immediately for inspection to prevent the expansion of faults.
