The 4WE6D6X/OFEG125N4K4 is produced by Bosch Rexroth within the WE Directional Spool Valves series and is used to route hydraulic flow in automated machinery. It conforms to nominal size 6, enabling compact manifold mounting in space-constrained power units. Four main ports let designers connect pressure, tank, and two actuator lines through one interface. The porting pattern meets ISO 4401-03-02-0-05 for compatibility with standard subplates. Actuation is delivered by a high-power wet-pin solenoid that features a detachable coil for quick replacement. That coil operates on 125 V DC and draws 0.17 A, allowing direct drive from common control supplies. Continuous power consumption is 30 W, which influences power-supply sizing and thermal calculations. An IP65 protection class seals the enclosure against dust and water, extending service life in exposed plant areas.
The valve withstands 350 bar at the pressure and work ports, making it suitable for high-pressure applications. Maximum flow is 80 l/min in direct-current operation, supporting medium-capacity actuators without excessive loss. Tank port pressure is limited to 210 bar, guiding return-line component selection. A detent mechanism holds the spool in its last position after the coil is de-energized to maintain circuit status during control interruptions. A small lockable mushroom manual override permits intentional shifting for setup or emergency action. Electrical hookup is via a K4 connector per DIN EN 175301-803, simplifying wiring and disconnection. The coil tolerates switch-off overvoltages up to 500 V, protecting the winding from inductive peaks created by rapid de-energization. Together these ratings allow reliable flow direction in automated hydraulic systems that demand high pressure, moderate flow, and secure manual fallback options.
