The 4WEH22D7X/6EW110N9ETK4/B10V valve belongs to the WEH Directional Spool Valves series and is manufactured by Bosch Rexroth for electrically actuated hydraulic flow control in automated machinery. It is specified with nominal size NG25, matching manifolds built to that cavity dimension. The function type is a 4-way design, so it directs flow between pressure, tank, and two work ports. A spool symbol D defines the neutral and switching positions used in circuit schematics. The component series 7X identifies the internal design revision. Work ports p, a, and b withstand a maximum operating pressure of 280 bar. The porting pattern follows ISO 4401-08-08-0-05, ensuring interchangeability with standard subplates. A throttle insert of 1.0 mm labeled B10 meters pilot flow for controlled shifting. FKM sealing material resists high-temperature oil and aggressive additives.
The unit is piloted by a 6E high-power valve that delivers the force needed to move the main spool under load. Its coil interfaces through a DIN EN 175301-803 K4 electrical connector for quick wiring. Pilot oil supply is taken internally through the ET gallery, removing the need for an external feed line. Pilot oil also returns internally via port T, simplifying manifold drilling. A pilot flow of 35 l/min supports the fastest achievable switching times. The pilot stage tolerates pressures up to 210 bar without performance loss. When the two-spool spring version is used, the pilot circuit must maintain at least 11 bar to initiate movement. Six mounting screws sized M12 × 60 and graded 10.9 secure the housing to the manifold during operation.
