The DG4V32NHMU1D730EU38 valve belongs to the DG4 Directional Valves series and is produced by Vickers for directing flow in automated hydraulic systems. Its closed-center spool blocks all ports in the neutral position to prevent unintended actuator movement, while the P, A, and B ports accept up to 350 bar (5000 psi) and the T port handles 210 bar (3000 psi) for compatibility with high-pressure circuits. A 30 W dc solenoid provides the shifting force, and the coil is built with Class F encapsulation and Class H insulation so it can remain powered continuously at a 100 % duty cycle. Energizing the coil moves the spool within 60 ms, and releasing power returns it in 40 ms, allowing rapid cycle times. Electrical hookup is completed through a DIN 43650 (ISO 4400) plug, simplifying maintenance and replacement.
Installation follows the CETOP 3 (NFPA D03) pattern, and the ISO 4401-AB-03-4-A interface with M5-0.8 mounting bolts aligns the valve to common subplates for straightforward swapping in manifolds. An IP67 enclosure keeps dust and water out of the solenoid housing, and a water-resistant manual override lets technicians shift the spool during setup or emergency conditions without energizing the coil. System oil must meet ISO 4406 19/17/14 cleanliness to minimize wear on the precision lands and seals, sustaining reliable operation over time. These mechanical, electrical, and environmental features make the valve suitable for industrial automation where consistent response and robust construction are required.
