The 4WEH22J7X/6EG24N9EK4/B10 SO43A-1058-A directional spool valve is produced by Bosch Rexroth within the WEH Directional Spool Valves series. It is an electro-hydraulic unit that shifts a main spool to route fluid in automated hydraulic circuits. Actuation is electro-hydraulic so a small pilot stage moves the spool with low force demand. The solenoid coil operates at 24 V DC, and the DIN EN 175301-803 K4 connector simplifies wiring inside manifold blocks. Nominal size 25 passages follow the ISO 4401-08-08-0-05 porting pattern for direct mounting. Spool code J permits a maximum flow of 450 l/min for high-volume actuators. Internal pilot supply draws pressure from port P, while pilot return is external at port Y to prevent back-pressure on the pilot stage. A minimum pilot pressure of 10.5 bar guarantees reliable switching under load.
Concealed manual override N9 lets technicians shift the spool without electrical power during commissioning or maintenance. A throttle insert with a 1.0 mm orifice identified as B10 can be installed to damp pilot flow and control response speed. Continuous service limits are 280 bar at ports P, A, and B, 250 bar at port T, and 210 bar at port Y, allowing planners to set matching relief valves. Fluid cleanliness must meet ISO 4406 class 20/18/15 so wear edges remain intact. These parameters define the valve’s operating envelope and ensure dependable flow direction in heavy-duty hydraulic systems.
