The 4WE6D6X/OFEG48N9K4 directional valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and routes pressurized hydraulic oil between actuator ports. A Wet-Pin High-Power solenoid shifts the spool to ensure reliable flow control under load, while a nominal voltage of 48 V DC lets the coil tie into common low-voltage supplies. Power consumption is capped at 30 W to limit heat in compact manifolds, and the valve draws 0.66 A so it remains compatible with standard relay outputs. A voltage tolerance of ±10 % keeps performance consistent when the supply varies, and the duty cycle of 100 % ED allows continuous energization without cooling pauses. A K4 plug conforming to DIN EN 175301-803 and an IP65 enclosure protect the electrical section against dust and water jets.
The subplate interface follows mounting pattern ISO 4401-03-02-0-05, enabling straightforward exchange on standardized manifolds. Maximum flow reaches 80 L/min to support medium-sized drives, and ports A, B, and P tolerate pressures up to 350 bar for high-pressure circuits. Port T withstands 210 bar in direct-current service, safeguarding the tank return line. A detent spool return holds the spool in its last position after de-energization, eliminating continuous power draw during steady states. The concealed N9 manual override permits hand actuation when electrical control is unavailable. NBR sealing material resists common hydraulic oils and maintains leak tightness, and the 1.95 kg assembly is light enough for single-person installation.
