The 4WEH16E7X/6EG24N9EK4/B10 valve belongs to the WEH Directional Spool Valves series and is produced by Bosch Rexroth for automated hydraulic circuits. It meters flow by shifting a spring-centered E-type spool between three positions to route pressure and return lines. The NG16 size works with subplates that follow the ISO 4401-07-07-0-05 porting pattern so installation is standardized. A 24 V DC solenoid coil drives the spool, and wiring is completed through a DIN EN 175301-803 K4 connector. A concealed manual override lets technicians move the spool without energizing the coil for setup or troubleshooting. The assembly weighs 8.9 kg which allows direct mounting on manifolds without additional supports.
Internal pilot supply draws system pressure to actuate the spool while an external pilot return sends pilot fluid back to tank to avoid cross-port interference. The valve functions with pilot pressures from 14 bar up to 250 bar so control remains stable over a broad range. Main flow paths accept operating pressures to 280 bar and pass up to 300 l/min to serve medium-to-high capacity actuators. A Ø1.0 mm throttle insert identified as option B10 moderates pilot flow for smoother shifting under variable load. These features complete the hydraulic control package and align the valve with machines that require reliable directional change at high flow rates.
