The 4WEH10J4X/6EG24N9ETK4/B10V valve belongs to the WEH Directional Spool Valves series produced by Bosch Rexroth. It directs hydraulic flow to actuators in automated machinery where reliable position control is required. The valve is sized NG10 so it mates with manifolds designed for 10 mm nominal passages and moderate flow rates. A 4-way path arrangement provides pressure, tank, and two working ports to handle bidirectional cylinder or motor circuits. The J-type spool geometry sets the flow paths for three-position service, and a spring-centered layout returns the spool to neutral when the solenoids are de-energized to prevent unintended motion. Electro-hydraulic actuation uses a pilot stage to shift the main spool with reduced electrical power, and the 24 V DC supply voltage matches common industrial control cabinets. The DIN EN 175301-803 K4 connector offers quick plug-in wiring, while a concealed manual override lets technicians move the spool mechanically during setup or power loss. The ISO 4401-05-05-0-05 porting pattern ensures interchangeability with standard sub-plates.
Maximum nominal flow of 160 l/min allows the valve to service medium-capacity circuits without excessive pressure drop. The main ports tolerate up to 280 bar operating pressure, supporting high-force actuators, whereas the pilot stage accepts a limit of 250 bar to protect the control components. Internal supply and return of pilot oil simplify plumbing, and the internal Y return path can handle back pressure to 210 bar when the coil is powered by direct current. A 1.0 mm throttle insert is fitted to damp pressure spikes and moderate shifting speed for smoother motion. Fluoroelastomer (FKM) seals permit the use of higher-temperature or synthetic fluids while maintaining leak-tight service life.
