The 4WE6Y1-6X/EG24N9DK23L/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. Intended to shift hydraulic flow in automation circuits, it uses nominal size 6 geometry so it integrates with NG6 subplates. A mounting interface that follows NFPA T3.5.1 R2-2002 D03 permits direct installation on standard manifolds, while the ISO 4401-03-02-0-05 porting pattern guarantees dimensional interchangeability with other NG6 products. The pressure boundary handles 350 bar on the P, A, and B work ports, allowing high-pressure supply and actuator lines, whereas the T return port sustains 210 bar during dynamic cycling to protect reservoir plumbing. A maximum flow of 80 l/min supports medium-speed cylinders and motors without excessive pressure drop. The solenoid is designed for a 24 V DC supply, draws 1.25 A at nominal conditions, and accepts ±10 % voltage deviation so the valve continues to shift reliably even when the control power fluctuates.
The electromagnetic assembly is rated for a 100 % duty cycle, enabling continuous energization during long machine sequences without coil damage. Power is delivered through a DK23L three-pole Brad Harrison connector that simplifies rapid changeout and meets industry wiring preferences. When electrical power is unavailable, a concealed manual override lets technicians move the spool mechanically; this feature is usable up to 50 bar back-pressure so troubleshooting can proceed under residual system pressure. Under prolonged activation the coil surface may reach 120 °C, so adjacent cable insulation and mounting hardware must tolerate elevated temperatures. The winding consumes 30 W, which balances response speed with low heat generation for compact valve banks. An IP65 enclosure rating resists dust ingress and low-pressure water jets, allowing installation on open machine frames or in wash-down environments.
