The 4WE6X48B6X/EG24N9K4 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. It shifts hydraulic flow paths to start, stop, or reverse actuators in automated machinery. The solenoid is sized for a nominal voltage of 24 V DC so that it integrates with common control power supplies, and it draws a rated current of 1.25 A to energize the coil. A voltage tolerance of ±10 % keeps the valve functional despite supply fluctuations, while the 30 W nominal power defines the electrical load that must be provided by the control system. Continuous energization is permitted because the duty cycle is 100 % ED, and the coil surface can reach up to 120 °C without damage, allowing extended on-time in warm environments. Wiring is performed through a DIN EN 175301-803 form K4 connector that also gives an IP65 protection class against dust and water jets, supporting exposed mounting conditions.
For hydraulic performance, the valve handles a maximum flow of 80 l/min so circuits can move moderate volumes without excessive pressure loss. The ports a, b, and p withstand operating pressure up to 350 bar, whereas the t port is limited to 210 bar, parameters that define manifold sizing and relief settings. Switching can occur at 4.2 cycles per second in direct-current operation, enabling rapid positioning sequences. The subplate interface follows the ISO 4401-03-02-0-05 porting pattern, which ensures interchangeability with standard size 6 mounting plates. A concealed manual override identified as type N9 lets maintenance staff shift the spool when power is absent, and this feature is rated for tank pressures up to 50 bar to avoid seal extrusion. Fluid cleanliness must meet ISO 4406 class 20/18/15 so the spool and lands remain free of abrasive wear, supporting long service life under the stated operating limits.
