DG4V32NMWB40S324

The DG4V32NMWB40S324 valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation circuits where directional control of oil flow is required. It conforms to CETOP size 3, allowing it to mount on standard subplates used in compact industrial manifolds. A flow rating of 40 l/min (10.5 US gpm) defines the maximum throughput the spool can direct without excessive pressure drop. The valve withstands working pressures up to 350 bar (5000 psi) at ports P, A, and B, so it can be applied in high-pressure power units. Its interface follows ISO 4401-AB-03-4-A, enabling quick replacement with other valves that share the same pattern. The NFPA mounting size D03 provides identical dimensional references for North American installations. Continuous operation is supported by a relative duty factor of 100 % ED, which permits energizing the solenoid without cycle limits.

For secure attachment, the valve body includes a counterbore diameter of 10.0 mm that seats cap screws below the surface and a through mounting hole diameter of 5.6 mm that accepts standard M5 hardware. Port spacing between P and A/B is 21.50 mm, aligning the internal galleries with matching manifold passages. Proper sealing requires a mount surface flatness of 0.013 mm so the O-ring lands remain fully compressed. A surface roughness of 1.1 µm Ra is specified to prevent micro-leakage across the interface. The hydraulic medium must be maintained at ISO 4406 cleanliness class 19/17/14, reducing wear on the spool and improving service life. These geometric and fluid requirements ensure that the DG4V32NMWB40S324 functions reliably when integrated into precision hydraulic control systems.
