The 4WE10W3X/CG24N9K4/V directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and is intended to shift hydraulic flow paths in automated circuits. It uses the W spool symbol to define a crossover flow pattern suited to rapid cylinder reversal, while its nominal size 10 establishes the interface dimensions for sandwich mounting. A wet-pin DC solenoid drives the spool and operates on a 24 V DC supply so the unit connects directly to common machine control voltages. Continuous energization is possible because the duty cycle is rated at 100 percent, and a maximum switching frequency of 15 000 cycles per hour supports high-speed sequencing. Wiring is handled through a three-pole EN 175301-803 connector, and a concealed manual override allows local actuation for setup or maintenance without disturbing electrical plugs. The assembly weighs 4.4 kg when equipped with two K4 solenoids, a consideration for manifold loading and support.
The ISO 4401-05-04-0-05 porting pattern matches standard subplates so the valve can replace similar components without re-machining. A center flow cross-section of 2.5 mm² determines the throttling area that controls pressure drop across the metering notches. The design passes up to 120 L/min, making it suitable for medium-capacity work circuits. Ports P, A, and B tolerate operating pressures to 315 bar, while port T is limited to 160 bar to protect return-line plumbing. FKM seals provide chemical resistance to modern hydraulic fluids and elevated temperatures, and an IP65 rating is achieved when the mating connector is fitted, guarding the solenoids against dust ingress and low-pressure water jets. The valve body carries a concealed override as noted earlier, and all remaining service points are protected by this enclosure rating to maintain reliability in harsh plant environments.
