The 4WE6D6X/OFEG12NK4/B10 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for directing hydraulic oil between actuators and pumps. Built in size 6 with a D spool symbol, it offers two flow patterns that match its two spool positions. Because there is no spring return and an OF detent is fitted, the spool remains in the selected state after electrical energization. An integrated Ø 1.0 mm throttle insert in the pressure port limits inlet flow to soften pressure spikes. When installed on an ISO 4401-03-02-0-05 (D03) subplate, the valve can carry up to 80 l/min through the dc flow path.
Electrical actuation is handled by a 12 V DC coil that draws 2.5 A and consumes 30 W, making it suitable for mobile or battery-powered systems. The solenoid uses a K4 DIN EN 175301-803 connector and the housing meets IP65, so wiring remains secure against dust and water jets. Ports a, b, and p tolerate pressures to 350 bar, while the tank port is rated for 210 bar to protect return lines. A type N manual override permits local shifting of the spool during commissioning or power loss, completing the valve’s control and safety features.
