The DG4V36CMWB730 directional valve belongs to the DG4 Directional Valves series manufactured by Vickers. It regulates oil flow in hydraulic automation by shifting a spool inside a subplate body. The unit employs spool type 6, which blocks the pressure port P and directs both A and B to tank when in its neutral state. A spring arrangement C centers the spool automatically when the solenoids are not energized. The valve attaches to manifolds that follow the CETOP 3 (NFPA D03) pattern, and its mounting face matches ISO 4401-AB-03-4-A for straightforward interchange. Ports P, A, and B are rated for 350 bar (5000 psi) so high-pressure circuits are supported, while the tank port withstands 207 bar (3000 psi).
The DG4V36CMWB730 is equipped with Class F coil encapsulation for insulation and Class H windings for high-temperature resilience, allowing continuous coil heating without damage. Electrical operation is maintained down to 90 percent of rated supply, and a relative duty factor of 100 percent ED permits nonstop energization in demanding cycles. When wired through an ISO 4400 plug the valve reaches IP67 protection, preventing dust ingress and temporary water immersion. These electrical attributes complement the hydraulic design, yielding a compact component that performs accurate directional control under sustained duty in automated machinery.
