The Z4WEH10E68-4X/6EG24NETK4/B10 directional valve from Bosch Rexroth belongs to the Z4WE Solenoid Actuation Spool Valves series. It provides 4/2-way flow control in hydraulic automation where cylinder extension and retraction must be selected electrically. Electro-hydraulic actuation shifts the NG10 spool with a 6E pilot stage so the main spool moves quickly under full system load. The E68 spool form defines the internal flow paths, while component series 4X indicates the current design generation. A permitted operating pressure of 315 bar lets the valve handle high-pressure circuits, and the ISO 4401-05-04-0-05 porting pattern together with NFPA size D05 ensures direct sub-plate mounting without adapters.
An internal supply and return pilot oil version (ET) removes the need for external pilot lines, simplifying manifold layouts. The valve accepts a 24 VDC coil supply and uses an EN 175301-803 three-pole plug with protective earth; the individual K4 connection style allows each solenoid to be wired separately for independent diagnostics. Peak flow capacity is 160 l/min, matching the NG10 passage size while keeping pressure losses low. A Ø 1.0 mm throttle insert stamped B10 can be fitted to meter pilot oil and dampen spool movement when softer shifting is required. A manual override is provided so technicians can position the spool during commissioning or when power is unavailable.
