The 4WE10G3X/CG12N9K4SO43A-1042 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for controlling hydraulic actuators in automated machinery. It is built around nominal size 10 geometry, and it conforms to the NFPA D05 mounting interface so it fits standard subplates. The porting pattern follows ISO 4401-05-04-0-05, providing four working ports for pressure, tank, and two actuator lines in accordance with the series layout. A G-configured spool shifts fluid between these ports and handles flow rates up to 120 l/min without exceeding the envelope limits. System pressure can reach 315 bar on the pressure port, while the tank port is limited to 210 bar during dynamic cycles. Reliable operation depends on fluid cleanliness held at ISO 4406 (C) 20/18/15 to protect the precision spool fit and reduce wear.
In electric actuation, the valve uses a 12 V DC coil that draws 35 W during steady energization, and the coil can be rotated 90° to accommodate space constraints in tight manifolds. The low-voltage design limits power dissipation, helping the solenoid remain within thermal limits during frequent cycling in mobile or industrial equipment. Power reaches the device through an EN 175301-803 three-pole connector identified as K4, and a concealed manual override designated N9 allows local shifting when power is absent. The enclosure achieves IP65 protection, safeguarding the internal winding and spool against dust ingress and water jets when a proper mating cable gland is installed. All electrical items are arranged to match the series envelope so that field service remains straightforward and consistent with other Rexroth directional valves.
