The 4WE6J73-6X/EG24N9DK24L1/H12SO407 valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that need repeatable on-off flow control. It employs a nominal size 6 spool so it fits subplates built to ISO 4401-03-02-0-05 porting, allowing straightforward interchange with other NFPA D03 components. A 24 V DC supply energizes the coil, and a voltage tolerance of ±10 % prevents nuisance trips when the machine bus varies. The coil draws 8 W, limiting heat rise while still producing the magnetic force required for reliable shifting. Continuous service is possible because the duty cycle is 100 % ED, and the coil surface is rated up to 85 °C so it remains within insulation limits during extended runs. At 1.95 kg for two solenoids the assembly can be mounted on light manifolds without extra bracing.
An M12×1 four-pin connector marked DK24L1 provides quick electrical hookup and, when mated, achieves IP65 ingress protection so the solenoids resist dust and low-pressure water. A concealed manual override identified by code N9 lets maintenance staff move the spool without power for troubleshooting. Hydraulic performance reaches 60 L/min of direct-current flow, with ports P, A, and B accepting 315 bar while the tank port tolerates 210 bar, supporting medium-pressure machines. A maximum switching frequency of two cycles per second keeps wear in check on continuous duty stations. The 1.2 mm throttle insert in port A moderates acceleration of actuators connected to that line, helping damp pressure spikes during rapid reversals.
