The 4WE6J6X/EG24N9DK25/B25 valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow paths in industrial automation systems with a wet-pin, detachable coil solenoid that simplifies replacement when service is required. The solenoid is energized by a nominal 24 V DC supply, draws 1.25 A, and absorbs 30 W, so actuation force remains stable under full load. A duty cycle of 100 % ED allows continuous energization without overheating, while the coil surface may reach up to 120 °C before thermal limits are met. Voltage variations of ±10 % are acceptable, preventing nuisance trips during supply fluctuations. Incoming power is routed through a DK25 five-pole Brad Harrison connector, and a concealed N9 manual override lets technicians shift the spool locally when electrical power is unavailable.
The hydraulic section passes up to 80 l/min through the spool when ports p, a, and b are held to a maximum of 350 bar, providing adequate flow for medium-capacity circuits without excessive pressure drop. The tank port tolerates 210 bar during return flow, ensuring safe depressurization in back-pressure conditions. Installation follows ISO 4401-03-02-0-05 with an NFPA D03 size, so the valve mounts directly on standard subplates used in compact manifolds. A throttle insert in port P with a 2.5 mm orifice restricts inrush velocity, protecting downstream components during rapid shifts. Total weight with two solenoids is 1.95 kg, allowing a single technician to install or replace the unit without lifting equipment.
