What Is the Danfoss DG4V Valve?
The Danfoss DG4V is a solenoid-operated hydraulic directional control valve used to control the direction and stopping of hydraulic fluid in a hydraulic circuit. It is commonly supplied as a subplate-mounted valve and can be configured with different spool types, spring arrangements, solenoid voltages, connectors and manual overrides.
The DG4V range includes different valve sizes for different flow requirements. The DG4V-3 family uses the ISO 4401-03 / CETOP 3 interface, while larger DG4V configurations are available for higher flow hydraulic systems. This flexibility makes the series suitable for hydraulic power units, mobile machinery, material handling systems and industrial automation equipment.

Check hydraulic fluid compatibility and select the appropriate seal configuration.
Danfoss DG4V FAQ
Q1. What is a Danfoss DG4V solenoid valve?
The Danfoss DG4V is a solenoid-operated directional control valve designed to direct, stop and switch hydraulic fluid in a hydraulic circuit. It is commonly used to control hydraulic cylinders and motors.
Q2. What is the maximum pressure of a DG4V valve?
Depending on the model, the DG4V-3M can be rated up to 350 bar, while the DG4V-5M can be rated up to 315 bar. The exact rating must be confirmed from the complete model code and technical documentation.
Q3. What flow rate can a DG4V-3 handle?
The Danfoss DG4V-3M family is specified for flow rates up to approximately 80 L/min, depending on the selected configuration and performance requirements.
Q4. What is the difference between DG4V-3 and DG4V-5?
The main differences are valve size, mounting interface, flow capacity and pressure rating. DG4V-3 is commonly associated with the ISO 4401-03 / CETOP 3 interface, while DG4V-5 configurations provide a larger flow capacity for higher-flow hydraulic circuits.
Q5. Which coil voltages are available for DG4V?
DG4V valves are available with different AC and DC coil configurations depending on the specific model. Common configurations include 12 VDC, 24 VDC and various AC voltage options.
Q6. Can I replace an old Vickers DG4V valve with a new Danfoss valve?
Replacement is possible when the mounting interface, spool function, solenoid configuration, pressure, flow and electrical requirements are compatible. The complete existing model code should be checked before ordering.
Q7. What hydraulic fluid can be used with a DG4V valve?
DG4V configurations are commonly specified for petroleum-based hydraulic oils, while seal selection must be matched to the fluid and operating conditions. Always verify fluid compatibility for the exact valve configuration.
Q8. What information should I provide when purchasing a DG4V valve?
Provide the complete model code whenever possible. Coil voltage, spool type, spring arrangement, mounting size, connector, seal material, pressure, flow and application information can help suppliers identify the correct hydraulic directional valve.
Need the Correct DG4V Configuration?
For hydraulic valve sourcing and replacement projects, the complete Danfoss / Vickers model code is the most reliable starting point. Matching the valve by appearance alone may result in an incorrect spool, coil, mounting interface or pressure specification.
Before Ordering
The Danfoss DG4V solenoid directional valve is a practical solution for hydraulic flow direction, actuator control and machine automation. Its combination of multiple spool configurations, electrical options, standardized mounting interfaces and proven endurance makes the DG4V series suitable for industrial hydraulic systems, mobile equipment, agricultural machinery, forestry equipment, material handling systems and other demanding applications.
