Bosch Rexroth 4WE10D5X/EW230N9K4/M solenoid-operated directional spool valve

4WE10D5X/EW230N9K4/M is a direct solenoid-operated directional spool valve with symbol D, four hydraulic ports and 2 switching positions. This size 10 subplate execution has NBR seals, a 230 V AC coil supply, a three-pole connector with protective earth, and concealed N9 manual override. The pressure ceiling at P, A and B is 350 bar; the separate T-port limit is 160 bar. Admissible flow depends on the spool-specific operating envelope, oil condition and return pressure.

The published pressure and flow limits are ceilings, not an assurance that both may be reached simultaneously. Selection and installation must follow the applicable performance curves, hydraulic-fluid restrictions, mounting requirements and seal-specific operating conditions.

The current factory article lists 145 L/min while the linked series sheet gives a 120 L/min AC ceiling. A single verified maximum-flow value is withheld pending manufacturer confirmation; pressure/flow operation must follow the applicable W230 and D-spool curves.
