DG5S4-04 models are two-stage directional valves having an integrally mounted DG4V-3(S)-60 pilot valve. These valves are generally used to control the direction of flow in a hydraulic circuit. This in turn would control the movement of a work cylinder or the rotation of a fluid motor
Features and Benefits
Suitable for the most demanding industrial applications with flow capacities up to 227 l/min (60 USgpm) and rated pressure of 210 bar (3000 psi).
Available with a wide variety of spool and spring arrangements, stroke and pilot choke adjustments, integral check valves, and port orifices.
Solid cast body with cored passages for maximum strength and minimal pressure drop.
Designed and manufactured by Vickers, with over 70 years as the global leader in fluid power and motion control.
Max. pressure: 210 bar (3000 psi)
Max. flow: 227 l/min (60 USgpm)

Spring centered, pressure centered and spring offset models must be energized continuously to maintain the shifted position. Detented no-spring models may be energized momentarily (approximately 0.1 second).
Pressure centered and spring centered models return valve spool to center position when solenoids are de-energized. Spring offset models return spool to offset position by pilot pressure when solenoid is de-energized.
When no-spring detented models are de-energized, the pilot and main spools remain in the last position attained, provided there is no shock, vibration, unusual pressure transients and the spool axis is horizontal. If pilot pressure fails or falls below the minimum, the main spool will spring center (at spring centered flow rates) and cannot drift to reverse flow (pilot stage remains in detented position).
