The DG4V37BMWB40 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation where selectable flow paths are required. It follows the CETOP 3 (NFPA D03) interface standard, allowing direct mounting to common subplates without adapters. The valve uses spool type 7, so pressure is directed simultaneously to ports A and B while the tank port remains closed when shifted. A spring arrangement B returns the spool to center when the solenoid is de-energized, ensuring fail-safe neutral positioning. A DC solenoid provides actuation and draws 30 W during operation. Continuous service is supported by a 100 % duty factor, enabling the solenoid to remain energized without overheating during extended cycles.
The solenoid winding is encapsulated to Class F standards, protecting the coil from vibration and moisture. Internal insulation meets Class H temperature limits, allowing the coil to tolerate elevated operating temperatures. Connection to the hydraulic manifold is made through an ISO 4401-AB-03-4-A mounting interface, matching many compact power units. The valve withstands pressures up to 350 bar (5000 psi) on ports P, A, and B, supporting high-pressure circuits. When an ISO 4400 plug is fitted, the enclosure achieves an IP67 protection rating, sealing the electrical parts against dust ingress and temporary water immersion. A single-solenoid version weighs 1.6 kg (3.5 lb), keeping manifold loading minimal during assembly.
