The 4WE6JB6X/OFEG24N9K4 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and is intended to direct hydraulic flow in automated machinery. It tolerates a maximum operating pressure of 350 bar on ports A, B, and P so it can be installed in high-pressure circuits. The spool permits a flow rate up to 80 l/min in DC operation, matching medium-size actuators without excessive pressure drop. Because the installation position can be any orientation, design engineers can mount the unit wherever space allows. The body follows the ISO 4401-03-02-0-05 porting pattern, which aligns with common subplates. A matching NFPA interface coded T3.5.1 D03 provides interchangeability with North American manifolds. The solenoid is energized with a nominal voltage of 24 V DC, draws 1.25 A under rated conditions, and therefore dissipates 30 W during steady operation.
The coil surface is allowed to reach 120 °C, so thermal design must ensure surrounding components withstand that temperature. Continuous operation is supported by a duty cycle of 100% ED in S1 mode, allowing the valve to remain energized indefinitely. Electrical termination is through a DIN EN 175301-803 connector, simplifying wiring and maintenance. An IP65 enclosure rating shields the internal parts from dust and low-pressure water jets, suitable for wash-down areas. The armature can shift the spool up to 4.2 times per second in DC service, offering responsive control in rapid cycling machinery. Tank port pressure is limited to 210 bar, which protects the return circuit from overload. With both solenoids fitted, the assembly weighs 1.95 kg, keeping overall manifold loading low.
