The 4WE6D6X/OFEG24N9DK24L2SO43A-1791 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and directs pressurized oil to actuator ports in hydraulic automation systems. It operates on a nominal voltage of 24 V DC, and the coils draw a rated current of 1.25 A, so control electronics can size conductors and fuses appropriately. Electrical demand is defined by a nominal power of 30 W, while a duty cycle of 100% (S1) allows the solenoids to remain energized without interruption during continuous machine cycles. A permitted coil surface temperature of 120 °C prevents insulation damage under prolonged load, and ambient temperatures up to 50 °C let the unit work reliably on factory floors. The circuit tolerates a ±10% supply variation, which maintains shifting performance when voltage fluctuates. The assembly weighs 1.95 kg with two solenoids, supporting easy installation on compact manifolds.
The valve accommodates system pressures up to 350 bar at ports P, A, and B, enabling use in high-pressure servo presses and hydraulic clamps. A maximum flow of 80 l/min establishes the throughput the spool can pass without excessive pressure drop, and a return-line limit of 210 bar defines the allowable tank port back pressure. Switching frequency reaches 4.2 cycles per second in direct-current operation, making it suitable for moderately dynamic positioning tasks. Electrical hookup is provided through a central M12×1 four-pole connector that simplifies plug-and-play wiring in modular panels. An IP65 protection class guards internal components against dust and water jets so the valve can be mounted in exposed areas. The mounting interface follows the ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability with standard size 6 subplates and manifolds.
