The 4WEH10J4X/6EW110N9EK4/B08V is a directional spool valve in the WEH Directional Spool Valves series produced by Bosch Rexroth. It directs hydraulic flow to actuators in automation circuits requiring fast response. The unit is built in valve size NG10 to fit systems that follow the ISO 4401-05-05-0-05 porting pattern. A 4-way configuration with spool symbol J provides two service positions for cylinders or motors. It sustains operating pressures up to 280 bar at ports P, A, and B, and handles flow rates as high as 160 l/min without excessive pressure drop. Overall weight is 6.8 kg which supports rigid mounting on standard subplates.
Control functions are managed by an integrated 6E pilot valve that takes supply internally from channel X and returns externally through channel Y, so main flow can be drained separately from pilot oil. Reliable actuation is maintained between 12 and 250 bar of pilot pressure. A throttle insert with a 0.8 mm orifice labeled B08 moderates pilot oil to prevent shock during switching. The valve offers a concealed manual override designated N9 for local shifting when power is absent. Electrical connection is provided by a DIN EN 175301-803 form K4 plug, and all dynamic seals are made from FKM to support high temperature or aggressive fluids.
