DG4V-3-0B-L-MPA3-WLB-P08-40

The DG4V-3-0B-L-MPA3-WLB-P08-40 directional valve is produced by Vickers for the DG4 Directional Valves series. It manages flow paths in hydraulic automation circuits through a spool type 0 design that creates an open center, allowing pump flow to return to tank when the valve is not energized. A spring-centered single arrangement returns the spool to neutral automatically to maintain safety on power loss. The unit follows a left-hand build layout, placing the solenoid and connector on the left when viewed from the P port side to match specific manifold orientations. Compatibility with ISO 4401-03 (CETOP 3) mounting dimensions permits direct installation on common subplates without additional hardware.

The hydraulic envelope withstands 350 bar (5075 psi) on the P, A, and B work ports, while the tank port is limited to 207 bar (3000 psi) to protect return-line components. Electrical actuation is supplied through a PA3 three-pin receptacle that supports quick coil replacement in the field. Wiring enters the enclosure through a 1/2 in NPT conduit thread to meet North American cabling practices. Flow into the valve body is metered by a 0.8 mm orifice in the P port, identified by the P08 code, which moderates response and reduces pressure shock. These features combine to provide consistent performance in compact hydraulic power units and machine manifolds.
