The DG4V3S22AMUHL760EN490 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation tasks that require controlled start, stop, and diversion of flow. Its 22 closed center two-way spool keeps all ports blocked in the neutral position, while the A spring offset returns the spool to this position when the coil is de-energized. A wet armature solenoid minimizes magnetic chatter and uses system oil for damping. The valve supports a rated flow of 40 l/min (10.5 US gpm) to accommodate medium-capacity circuits. Ports p, A, and B can operate at pressures up to 350 bar (5000 psi), and the tank port safely withstands 210 bar (3000 psi). Installation is through the ISO 4401-AB-03-4-A sub-plate interface, making it compatible with widely used manifold patterns.
The electrical section is designed for continuous service in automated lines. A Class F encapsulation surrounds the coil to guard it against vibration and hydraulic fluid. An ISO 4400 (DIN 43650) connector simplifies field wiring and allows fast coil replacement. Class H insulation tolerates high winding temperatures, and the duty cycle is specified at 100 percent ED, so the solenoid can remain energized indefinitely without overheating. Sealing provisions give the valve an IP67 ingress rating, allowing temporary immersion and protection from dust. Energizing the coil shifts the spool within 60 ms, and de-energizing returns it in 40 ms, supporting precise timing in high-cycle machinery. Together these electrical features complement the hydraulic ratings described earlier to provide consistent, delay-free directional control in industrial power units.
