The 4WE6J6X/EG24NK4/B10V spool valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series and directs pressurized oil in hydraulic automation circuits to start, stop, or change actuator movement. The solenoid coil is supplied with 24 V DC, and a rated current of 1.25 A delivers predictable magnet force during every shift. Its coil surface may reach 120 °C under continuous duty, so Class F insulation is used to tolerate the winding temperature. A 3-pole (2+PE) DIN EN 175301-803 connector provides quick electrical hookup with protective earth continuity, while an IP65 enclosure protects internal parts from dust and low-pressure water. The valve can be installed in any orientation to simplify manifold layout. It bolts to an NFPA D03 interface, and the porting pattern follows ISO 4401-03-02-0-05 to ensure interchangeability with standard subplates.
The unit handles a maximum flow of 80 l/min with DC excitation, enabling medium-size cylinders and motors to operate without excessive pressure drop. Ports A, B, and P tolerate up to 350 bar, whereas port T is limited to 210 bar, defining safe line ratings when connected to high-pressure pumps and low-pressure returns. The manual override functions as long as tank pressure stays below 50 bar, offering emergency shifting capability during power loss. A 1.0 mm throttle insert in port P dampens inlet surges that could otherwise damage downstream components. FKM seals withstand hydraulic oils and elevated temperatures, maintaining leakage control and reducing service intervals. The mean time to dangerous failure is 300 years, giving designers a high reliability figure for safety calculations. Together, these fluid, mechanical, and durability attributes allow the valve to integrate into automated presses, test rigs, and material-handling equipment that require consistent directional control.
