DG4V3S6NMFPA5WLB560

The DG4V3S6NMFPA5WLB560 directional valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation circuits. It regulates oil flow up to 40 l/min so actuators receive the required volume without cavitation. Its spool profile is arranged as P blocked with A and B routed to T, allowing a neutral position that unloads both work ports to tank while isolating pressure supply. The unit withstands 350 bar (5000 psi) on the P, A, and B ports, supporting high-pressure industrial systems, while the tank port tolerates 210 bar (3000 psi) to match return-line ratings. Installation follows the ISO 4401-AB-03-4-A interface to simplify manifold mounting across standard subplates. A wet armature solenoid drives the spool so the magnetic components remain lubricated by system fluid and generate minimal wear. The coil is wound for DC service, and a duty cycle of 100 % ED keeps the valve responsive during continuous energization.

A coil rated at 30 W supplies the magnetic force needed to shift the spool without excessive heat rise. Encapsulation to Class F insulates the windings against elevated temperatures, and a separate Class H winding grade further improves thermal endurance. Flying leads exit the coil, giving flexible routing when space around the installation is limited. A 5-pin receptacle serves as the field connector so wiring can be detached quickly for maintenance. The coil draws reliably as long as the supply remains at least 90 % of the rated voltage, preventing sluggish actuation during brownouts. A 1/2 in NPT thread on the conduit entry accepts common gland fittings, protecting the leads from mechanical strain. All these electrical features integrate with the wet armature actuator to keep the valve operating within specification while the hydraulic passages handle the pressures defined earlier.
