The 4WEH10D4X/6EW110NETDAL/B10 belongs to the WEH Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation where controlled directional flow is required. The valve employs electro-hydraulic actuation, allowing a solenoid-driven pilot stage to shift the main spool. It is configured as a 4-way unit, and its nominal size NG10 defines passage dimensions suitable for systems that handle up to 160 l/min. Working ports P, A, and B tolerate a maximum operating pressure of 280 bar, enabling use in high-pressure circuits. A porting pattern that matches ISO 4401-05-05-0-05 aligns the body with standard subplates, while subplate mounting simplifies replacement during service. Electrical hookup is completed through a DIN EN 175301-803 K4 connector that supports quick field wiring and secure strain relief.
A 4WE6E pilot control valve shifts the main stage, and pilot oil is supplied internally through path ET while returning internally to tank at port T, eliminating external jump lines. The pilot section withstands pressures up to 250 bar, and a manual override marked N lets technicians reposition the spool during setup or power loss. Flow stability in the pilot gallery is assisted by a 1.0 mm throttle insert coded B10. System cleanliness must reach ISO 4406 20/18/15 to protect the closely fitted spool lands from abrasion. During installation, M6 × 45 mounting bolts are tightened to 12.5 Nm to seat the valve evenly on its manifold face and prevent leakage.
