The 4WE6M6X/EW110N9DK25L/B08V directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automated machinery and mobile equipment. The valve features nominal size 6 to match circuits designed around the ISO 4401-03 interface, and the mounting pattern follows ISO 4401-03-02-0-05 so it bolts directly to standard subplates. Its solenoid assembly accepts 110 V AC at 50 or 60 Hz, drawing 0.52 A at 50 Hz and 0.39 A at 60 Hz, enabling straightforward wiring to common control transformers. The electrical winding is built to insulation class H to tolerate elevated coil temperatures during sustained duty. A 5-pin Brad Harrison connector with an integral LED provides detachable power and visual energization feedback. The valve passes up to 60 l/min at the stated nominal flow while withstanding 350 bar on ports P, A, and B, supporting high-pressure servo loops in compact manifolds.
Protection elements and service features complete the design. An IP65 enclosure rating keeps dust and low-pressure water jets out of the solenoid housing when the connector is fitted. FKM seals resist synthetic fluids and higher temperatures common in modern hydraulic oils. The concealed manual override allows local actuation without exposing the coil to contamination. The return line can handle 160 bar at port T, maintaining back-pressure capability in closed loop systems, while a Ø0.8 mm throttle insert in port P dampens pressure spikes as the spool shifts. Cleanliness requirements of ISO 4406 class 20/18/15 limit particle ingress to prevent spool sticking and premature wear. Total weight with two solenoids is 1.95 kg, so the valve adds minimal mass to a manifold block yet remains light enough for single-person installation.
