The 4WE6E6X/EG24N9K40 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressurized fluid to selected actuator ports in mobile or industrial hydraulic automation. The solenoid section is designed for a nominal voltage of 24 V DC, and a voltage tolerance of ±10 % keeps actuation reliable under varying supply conditions. At 24 V the coil draws a rated current of 1.25 A and consumes 30 W, so standard machine power supplies can drive the coil without extra converters. Continuous energization is permitted because the duty cycle is 100 %, while a maximum switching frequency of 4.2 cycles per second supports rapid control loops. Transient suppression must account for a switch-off overvoltage that can peak at 500 V. Electrical termination is through a Deutsch DT04-2PA connector in the K40 variant, and the molded housing attains an IP69K ingress rating so outdoor equipment and high-pressure washdowns do not compromise the coil.
The hydraulic section follows the ISO 4401-03-02-0-05 porting pattern, allowing the valve to mount on standard size 03 sub-plates without additional adapters. It handles a maximum operating pressure of 350 bar at ports A, B, and P, while the tank port tolerates up to 210 bar in direct current service, covering most mid-pressure circuits. Permissible flow reaches 80 l/min, giving adequate capacity for medium-sized cylinders and motors. A concealed manual override, identified by option N9, lets technicians shift the spool during commissioning; this operation is rated for tank pressures up to 50 bar to avoid seal damage. System oil must be maintained to cleanliness class 20/18/15 according to ISO 4406 to protect the tight spool clearances from contamination-related wear. These hydraulic attributes, combined with the sealed electrical design described earlier, establish the 4WE6E6X/EG24N9K40 as a compact interface between electronic control signals and high-pressure fluid power.
