FLUID POWER CONTROL SERIES
DG4V-3 Solenoid Directional Valve for Hydraulic Circuit Control
Electrical switching. Controlled oil routing. Flexible integration into compatible industrial hydraulic systems.
Danfoss / Vickers DG4V-3 series hydraulic directional control valve for equipment manufacturers, hydraulic system integrators and maintenance professionals.
01. Product Introduction
The DG4V-3 solenoid operated directional control valve is designed to change hydraulic oil flow paths in response to electrical control signals. By shifting an internal spool, the valve connects selected hydraulic ports to support the movement of cylinders, hydraulic motors and other compatible actuators.
For machine builders and hydraulic power unit manufacturers, a directional valve is an essential component in coordinating machine movements. The DG4V-3 family offers different spool arrangements and actuation configurations, allowing engineers to select a suitable valve for the intended circuit function.
When sourcing a DG4V-3 hydraulic valve for maintenance or replacement, confirm the complete model designation, spool symbol, mounting dimensions, coil voltage and pressure ratings. These details help prevent mismatches between the replacement valve and the original hydraulic system.
02. How Hydraulic Flow Is Controlled
The directional valve works as part of a larger hydraulic circuit. Its function is determined by the spool configuration and the system connections.
Electrical Signal
The machine controller commands a selected solenoid.
Spool Shift
The spool changes position according to the valve design.
Oil Routing
The selected ports establish the required flow path.
Actual port connections and return behavior depend on the spool symbol, spring arrangement and circuit design.
