The Vickers DG4S4LW-016A-B-60 is a heavy-duty, solenoid-operated, sliding spool directional control valve engineered for the automated management of hydraulic fluid routing in heavy machinery. This direct-acting valve is built onto the standard ISO 4401-05 subplate interface (equivalent to NFPA D05 and CETOP 5 standards), making it a universal choice for plant modernizations or legacy equipment repairs.
What sets this valve apart is its “LW” wet armature solenoid design. By housing the armature assembly directly within the hydraulic fluid, the fluid acts as a natural dampener. This radically reduces mechanical impact noise, aids in coil heat dissipation, and eliminates external pushpin seals that are highly prone to weeping or leaking over extended cycles. The “6A” spool type offers a precise flow pathway configuration with a dependable spring offset mechanism, guaranteeing positive system control.
Core Technical Features & Advantages
-
Minimized Wear via Fluid Damping: Wet-armature design eliminates the primary wear points of dry-pin solenoids, dramatically lowering lifetime maintenance costs.
-
High Efficiency Cast Iron Body: Engineered with extra-large, smooth internal fluid passages to keep pressure drop ($\Delta p$) minimal, maximizing system energy efficiency.
-
Proven Series 60 Architecture: Represents Vickers’ highly refined 60-series design, incorporating optimized clearances and tighter manufacturing tolerances to control inner spool leakage.
-
Industrial Electrical Reliability: Heavy-duty AC solenoid coils are built to handle voltage fluctuations and continuous-duty cycles without fading or overheating.
-
Flexible Subplate Mount: Installs securely onto standard D05 industrial multi-station manifolds or single-station subplates.
