The 4WE6J6X/EG24NK4/B10 directional spool valve is part of the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation systems that require electrically actuated flow control. It operates in pressure lines up to 350 bar, allowing it to direct high-pressure oil to actuators without external pressure reducers. A maximum flow rate of 80 l/min supports moderate-to-high volume circuits, and a throttle insert with a 1.0 mm orifice in port P dampens pressure spikes during rapid shifts. The hydraulic fluid must meet a cleanliness class of 20/18/15 to prevent spool wear and sticking. Tank port T can withstand 210 bar, enabling use in circuits where back-pressure is present. A coil duty cycle of 100 percent ED allows continuous energization without overheating, while the 24 V DC nominal voltage with a ±10 percent tolerance matches common machine control supplies.
Electrical consumption is kept low with a 30 W nominal power draw and a rated current of 1.25 A, simplifying sizing of power supplies and relay contacts. The coil surface can reach 120 °C, so adjacent components must be arranged to handle that temperature. A K4 connector conforming to DIN EN 175301-803 provides standardized wiring, and the housing achieves an IP65 ingress protection level when the plug is properly fitted, sealing it against dust and water jets. A manual override is not included on this variant, yet the design allows an override assembly that tolerates tank pressures up to 50 bar if retrofit is required. These electrical and mechanical characteristics enable reliable spool positioning in demanding mobile or industrial environments without additional enclosure measures.
