The 4WEH10J4X/6EW110N9DA directional spool valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth. Designed to shift hydraulic flow paths in automated circuits, it uses a 4/3-way configuration so that pressure, tank, and work ports can be interconnected in three discrete positions. The J-coded spool installed in this NG10 unit defines the flow paths for symbol J applications. It fits on a subplate and matches the ISO 4401-05-05-0-05 mounting pattern, simplifying manifold integration. A spring-centered return recenters the control spool when the pilot signal is removed, and the design relies on an external X pilot oil supply with an external Y pilot oil return. The spring-centered version displaces 2.04 cm³ of pilot fluid per shift, and reliable actuation begins at a pilot pressure of 12 bar.
During operation the valve passes up to 160 l/min, while pressure at ports P, A, and B may reach 280 bar without derating. The same 280 bar limit applies to the tank port t, and the pilot stage tolerates a maximum of 250 bar. Circuit cleanliness must stay within ISO 4406 code 20/18/15 to protect the internal lands and seals. Electrical actuation is carried out through a connector conforming to DIN EN 175301-803, allowing quick attachment of standard coils. These ratings ensure consistent switching performance for hydraulic automation tasks that require compact valves with controlled flow, defined pressure limits, and repeatable electrical triggering.
