Vickers Proportional Valve DG4V-5-2AJ-M-U-H6-20 High Power Low Pressure Drop High Flow Capacity 350 Bar

Description:

The Vickers Proportional Valve DG4V-5-2AJ-M-U-H6-20 is a high-performance electro-hydraulic proportional directional control valve under the Eaton Vickers brand. This proportional valve controls the flow and direction of hydraulic fluid through the current control of an electromagnetic coil, enabling precise regulation of hydraulic system operations. The various components of the model number represent different parameters and configurations. For example, “DG4V” indicates that the valve belongs to the DG4V series, “5” indicates the valve's bore size of 5mm, ‘2AJ’ indicates the valve's control method and function code, and “M-U-H6-20” indicates the valve's mounting method, seal material, and other specific configurations.
 

Application Areas:

The Vickers Proportional Valve DG4V-5-2AJ-M-U-H6-20 is widely used in various industrial fields, particularly in applications requiring precise control of hydraulic systems. Its primary application areas include:
Construction Machinery: Hydraulic systems in equipment such as excavators and loaders, used to control the operation of hydraulic cylinders and hydraulic motors, enabling precise manipulation.
Mining machinery: In mining equipment, it is used to control the extension, retraction, and rotation of large hydraulic cylinders to adapt to complex mining environments.
Machine tools: In precision machining equipment such as CNC machine tools, it is used to control hydraulic transmission systems to ensure processing accuracy and stability.
Plastic machinery: In equipment such as injection molding machines, it is used to control mold opening/closing and material flow to improve production efficiency and product quality.
Woodworking machinery: Used to control the hydraulic systems of woodworking equipment, enabling operations such as wood cutting and shaping.
Additionally, this proportional valve can be applied in other scenarios requiring precise control of hydraulic systems, such as marine hydraulic systems and aerospace hydraulic systems.
 

Advantages:

The Vickers Proportional Valve DG4V-5-2AJ-M-U-H6-20 offers the following significant advantages:
Efficient control: It can efficiently control larger hydraulic power without increasing the power consumption of the solenoid valve. This efficiency enables the valve to perform exceptionally well in high-load and high-frequency applications while reducing energy consumption and operational costs.
High power-to-weight ratio: The valve has a high power-to-weight and size ratio, saving installation costs and space. This is particularly important for hydraulic systems requiring compact designs, such as in construction machinery or machine tools with limited space.
Installation Flexibility: By selecting from various solenoid valve connectors and position combinations, the valve offers high installation flexibility. This allows engineers to flexibly arrange the valve's position and connection method according to specific system design requirements.
Multi-Fluid Capability: The standard configuration with Viton seals provides multi-fluid capability, enabling compatibility with different hydraulic media. Additionally, nitrile seals are available as an option to meet specific medium requirements.
High Durability: With over 20 million cycle tests, the valve's fatigue life and durability have been thoroughly validated. This ensures stable performance during prolonged operation, minimizing downtime and maintenance costs caused by valve failures.
Quick Coil Replacement: The electromagnetic coil can be quickly and easily replaced without causing hydraulic system leaks during the process. This feature significantly enhances system maintenance efficiency and reliability.
Compact design: When used with Eaton® SystemStak™ valves and base plates, the system design is more compact and cost-effective. This compact design not only saves space but also reduces system complexity and costs.
Low pressure drop: At a flow rate of 30 liters per minute, the valve's minimum pressure drop is only 2.5 bar. A low pressure drop means the system can operate more efficiently, reducing energy loss.
Wide range of connectors and power options: Coil connectors include various types such as DIN, Deutsch, AMP, and junction boxes. Additionally, coil voltage and power options are abundant, catering to the needs of different users.
High flow capacity: At 350 bar (5,000 psi) pressure, the valve's flow capacity reaches up to 80 liters per minute (21 US gallons per minute) and 40 liters per minute (10.5 US gallons per minute). This high flow capacity enables it to meet the demands of high-power hydraulic systems.
