The 4WE6M10B6X/EG24N9K4 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and switches hydraulic flow in automated machinery. Its solenoids run at a nominal voltage of 24 V DC, and the rated current of 1.25 A sets the required power supply capacity. The coil surface can reach 120 °C during continuous duty, so thermal spacing must be considered. A DIN EN 175301-803 three-pin connector provides the electrical interface, while an IP65 enclosure protects the coil from dust and water jets. The porting pattern follows ISO 4401-03-02-0-05, letting the valve bolt directly onto standard D03 manifolds, and the mounting surface roughness of Rzmax 4 secures leak-free sealing with the gasket. With both solenoids the unit weighs 1.95 kg, and an MTTFd of 300 years supports long functional safety intervals.
The hydraulic section is rated for a maximum pressure of 350 bar at ports P, A, and B, while the tank port tolerates 210 bar, allowing elevated back-pressure without damage. During direct-current operation it conducts up to 80 l/min, supporting medium-flow circuits. A concealed manual override lets technicians shift the spool without power, and its use is limited to 50 bar to protect internal components. Installation matches the NFPA T3.5.1 R2-2002 D03 mounting standard, giving interchangeability with common subplates. These pressure, flow, and service features align the valve with demanding hydraulic automation tasks.
