The 4WE6LB6X/OFEG205N9K4 valve is part of the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow to automate cylinder or motor movement. Nominal size 6 sets a compact envelope for installations where space is limited, while the ISO 4401-03-02-0-05 mounting pattern matches common subplates for quick interchangeability. Four main ports let the circuit separate pressure, return, and two actuator lines without additional manifolds. The unit tolerates 350 bar at ports a, b, and p so it can be placed in high-pressure sections, and it limits the tank port to 210 bar to protect the return line. A direct-current solenoid passes up to 80 l/min, giving moderate flow capacity for medium-sized actuators. Electrical supply is 205 V DC with a ±10 % window, and the coil draws 0.16 A at 30 W, figures that help designers size power supplies and wiring.
The solenoid is rated for a 100 % ED duty cycle so it may remain energized continuously without duty-cycle timing. Coil insulation withstands a surface temperature of 120 °C, defining the thermal ceiling before service is required. An IP65 enclosure blocks dust and low-pressure water jets, allowing the valve to operate on open machine frames. A concealed manual override identified as N9 sits beneath a cap to prevent accidental shifts; it can be used when the tank line is below 50 bar for safe depressurization during service. These characteristics combine to deliver a directional valve that runs nonstop, resists harsh environments, and offers guarded manual control for maintenance crews.
