4WE6D6X/OFEG110N9K4/V

The 4WE6D6X/OFEG110N9K4/V valve is built by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automation circuits. With a nominal size of 6, it fits manifolds where compact envelope and moderate flow capacity are required. The ISO 4401-03-02-0-05 porting pattern enables direct mounting on standardized subplates to simplify installation. A maximum operating pressure of 350 bar at ports p, a, and b allows the valve to handle high-pressure work lines, while the tank port withstands 210 bar so return flow can be routed without supplemental relief devices. The direct-current version passes up to 80 l/min, supporting fast actuator movement in mobile or industrial systems. FKM sealing material resists aggressive hydraulic media and elevated temperatures, preserving leakage integrity over long service life. An IP65 protection rating shields the coil and connections from dust and water jets, making the unit suitable for outdoor or wash-down environments. Continuous duty at 100 % ED lets the solenoid remain energized indefinitely without exceeding thermal limits in demanding cycle sequences.

The electrical package is matched to 110 V DC supplies, so control cabinets can run the valve directly from common battery or rectified sources without additional converters. During actuation it draws a rated current of 0.25 A, a figure that eases sizing of power supplies and wiring. Nominal power of 30 W keeps heat generation modest, allowing close mounting to other components. The coil’s surface is limited to 120 °C, preventing insulation damage and maintaining operator safety near hot equipment. A DIN EN 175301-803 plug coded K4 provides a quick-disconnect connector that speeds replacement and ensures correct pin orientation. The spool is held in its last shifted position by a detent identified by the OF code, which maintains flow direction after power is removed. When manual intervention is necessary, a concealed N9 override lets technicians shift the spool without dismantling adjacent modules, protecting the mechanism from accidental activation. Together these features integrate electrical control and mechanical fallback options for reliable hydraulic switching.
