The 4WH6E5X/5 valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and is intended to route hydraulic flow in automated circuits. It is hydraulically actuated and uses spool type E to establish three switching positions for directional control. Four working ports are provided, and a spring return centers the spool when pilot pressure is released. The valve attaches to machinery through a subplate interface, following the CETOP D03 mounting pattern specified as ISO 4401-03-02-0-05, so interchange with common manifolds is straightforward. With a nominal size 6 it suits compact power units where space is limited yet precise path selection is required.
System limits include a maximum operating pressure of 315 bar and a separate port-T rating of 160 bar, enabling safe discharge of return flow. The unit carries a maximum rated flow of 60 l/min and demands at least 6 bar pilot pressure to shift the spool. Internal sealing is handled by NBR material that resists standard mineral oils, while acceptable fluid cleanliness is ISO 4406 class 20/18/15 to maintain spool tolerances. Total mass is 1.620 kg, allowing straightforward handling during installation or service. These characteristics define consistent performance in hydraulic manifolds where rapid, reliable direction changes are required.
