The 4WE6D6X/OFEW230N9K4/B10 valve is part of the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation that requires reliable flow switching. Its solenoid is designed for a 230 V AC 50/60 Hz supply so it can be wired directly to common industrial mains. A switch-on power draw of 220 VA produces the magnetic force needed to shift the spool quickly, after which the holding power drops to 50 VA to minimize heat and energy use. Continuous operation is permitted because the coil is rated for a 100 % duty cycle and a surface temperature limit of 120 °C. Electrical connection is made with a DIN EN 175301-803 (K4) plug that locks securely against vibration, and an IP65 enclosure keeps dust and water jets away from internal parts during field service.
The valve mounts to subplates or manifolds that follow the ISO 4401-03-02-0-05 porting pattern, allowing standardized installation in compact power units. It handles up to 350 bar at ports P, A, and B while the tank port tolerates 160 bar, supporting high-pressure circuits without external relief components. A maximum flow of 60 l/min passes through the metering slots, and the spool can be shifted up to two times per second when rapid cycling is required. A 1.0 mm throttle insert in port P moderates pressure rise to protect downstream actuators, and a concealed N9 manual override lets maintenance staff reposition the spool if power is lost. The assembly weighs 1.95 kg, so a single technician can remove or install it without lifting equipment.
