The 4WE6J6X/EG24N9K4/ZV/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery where electrical actuation is required. The valve draws 30 W at a nominal supply of 24 V DC, supporting low-power control architectures. A wet-pin solenoid with a detachable coil simplifies replacement while keeping the armature immersed in oil for consistent damping. Continuous energization is permissible because the assembly is rated for a 100 % duty cycle. Voltage may fluctuate by ±10 % without affecting switching, improving tolerance to supply variation. Wiring is completed through the K4 plug connector (2 + PE, Design A), and a concealed N9 manual override allows local shifting during commissioning. The coil is fixed by a 22 mm clamping length, and mounting alignment is aided by a locking pin that matches ISO 8752-3x8-St.
The hydraulic interface follows the ISO 4401-03-02-0-05 porting pattern and conforms to the NFPA T3.5.1 D03 footprint, so the valve fits standard subplates without adapters. Ports P, A, and B can be pressurized to 350 bar, while the tank line withstands up to 210 bar in direct-current service, allowing installation in high-pressure circuits that return oil through restrictive plumbing. With clean oil at rated viscosity, the spool passes up to 80 l/min, providing adequate flow for medium-sized cylinders and motors. The electromagnet can cycle the spool at 4.2 operations per second, supporting fast indexing sequences in production equipment. All dynamic seals are manufactured from FKM, which resists heat and aggressive fluids to maintain service life.
