The 4WEH10L4X/6EG24N9EK4/B10 valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series. It directs hydraulic flow in automation circuits where rapid switching and reliable pressure handling are required. The unit uses electro-hydraulic actuation so a pilot stage converts electrical commands into spool movement. A 4-way flow path allows separate pressure, tank, and two working lines, and the NG10 nominal size matches subplates that handle medium flow rates. The main ports withstand up to 280 bar, while the pilot return line is rated for 210 bar to protect the drain circuit. Pilot oil is taken internally from the pressure port, then discharged externally through port Y, which simplifies installation when back pressure is expected in the tank gallery. A throttle orifice of 1.0 mm in the pilot channel stabilizes the control signal and damps pressure spikes during spool shifts.
Electrical control is supplied by a 24 V DC coil that plugs into a DIN EN 175301-803 form K4 connector for standardized wiring. The low-voltage coil minimizes heat generation and allows direct drive from common PLC output cards. A concealed manual override identified by code N9 permits local actuation during commissioning without exposing moving parts. The mounting face follows the ISO 4401 porting pattern so it aligns with common manifolds and eliminates custom drilling. NBR seals contain the fluid and allow ambient temperatures up to 50 °C and fluid temperatures up to 80 °C in standard mineral oils. The sealing material also tolerates pressure fluctuations without compression set. The design accommodates hydraulic media with viscosities up to 500 mm²/s, supporting cold-start conditions and high-viscosity fluids. Together, these characteristics support dependable switching cycles over a long service life in mobile or stationary power units.
