The 4WEH10E4X/6EG24N9K4/V valve is produced by Bosch Rexroth and belongs to the WEH Directional Spool Valves series. It directs hydraulic flow in automated circuits and is built in size NG10 so it mates with standard subplates of that size. The internal spool follows symbol E, providing the flow paths required for four-way control. When that spool is used the unit passes up to 160 l/min without exceeding pressure drop limits, and it withstands 280 bar on ports P, A, and B during continuous duty. Electrical actuation is supplied by a 24 V DC pilot coil, connected through a DIN EN 175301-803 (K4) plug for quick replacement. The pilot oil enters externally through port X while return oil leaves externally through port Y, which lets the main ports operate at differing pressures.
Port T tolerates 280 bar and port Y is limited to 210 bar, allowing separate drain routing in systems with high back-pressure. The valve operates between −15 °C and +50 °C, matching typical industrial machine environments. Hydraulic cleanliness must meet ISO 4406 class 20/18/15 to avoid spool sticking. A concealed manual override labeled N9 permits mechanical shifting during commissioning or in the event of power loss. Mounting follows the ISO 4401-05-05-0-05 pattern so the body drops onto common NG10 manifolds. FKM seals identified by the V suffix resist mineral oil and elevated temperature, extending service life under the stated conditions.
