DG4V3S2NMFWB560

The DG4V3S2NMFWB560 valve belongs to the DG4 Directional Valves series produced by Vickers for hydraulic automation circuits that require repeatable control of actuator direction. It employs a spool type 2 configuration that closes all ports in the neutral position so downstream loads hold position when the solenoids are de-energized. A rated flow of 40 l/min (10.5 US gpm) defines the maximum volume it can route without excessive pressure drop, while a working limit of 350 bar (5000 psi) on the P, A, and B lines allows use on high-pressure power units. The mounting interface follows ISO 4401-AB-03-4-A, and the envelope also meets the CETOP 3 (NFPA D03) pattern so the valve can bolt directly onto common sub-plates. At 2.2 kg (4.8 lb) for the double-solenoid version, handling and panel assembly are manageable by one technician. Class F coil encapsulation insulates the conductor from hydraulic heat and fluid splash, extending service life in confined manifolds.

A wet armature solenoid design keeps moving parts submerged in oil to damp shock and reduce wear during rapid shifting. The coil is energized from a DC supply, and its windings are built to Class H temperature ratings so the insulation endures elevated ambient and coil self-heating. Continuous operation is supported by a 100 % ED duty cycle, allowing the valve to remain powered without cooling intervals. The F-style coil uses flying leads to simplify field wiring when space restricts the use of molded connectors, and the conduit entry is a 1/2 in NPT thread to match standard hydraulic junction boxes. Reliable actuation is maintained as long as the applied voltage stays above 90 % of the nominal rating, preventing sluggish spool movement under low-voltage conditions.
