The 4WEH22D7X/6EW110N9ETDK25L/B10V AN valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series and directs pressure oil in automated hydraulic machinery. Electro-hydraulic actuation lets an electrical signal move the main spool by pilot pressure, so electronic controllers can command flow remotely. The valve handles four flow paths because it is a 4-way unit, and the D-coded spool offers two discrete positions for extend-retract tasks. Nominal size NG25 aligns with mid-range circuits and fits size-08 manifolds. A maximum flow of 450 l/min at 210 bar keeps pressure loss low in high-volume systems, while ports P, A, and B tolerate 280 bar operating pressure for heavy-duty service. Shifting force comes from the high-power 4WE 6E pilot valve, ensuring consistent response. Control oil is taken internally from port X, eliminating an external pilot line and simplifying installation.
A concealed manual override (N9) lets technicians shift the spool during setup without exposing the mechanism to dirt. The pilot circuit accepts up to 210 bar, and reliable switching is maintained down to 11 bar in two-position operation. Internal supply begins working once pressure in line X reaches 4.5 bar, reducing startup delay. Pilot oil returns internally through port T, so subplate drilling remains simple. The mounting face follows ISO 4401-08-08-0-05, allowing direct interchange with standard subplates. FKM seals resist heat and aggressive fluids for longer service life. A 1.0 mm throttle insert identified as B10 can be installed to damp pressure spikes and meter pilot flow.
