The 4WEH10G4X/6EG24N9DAL valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and is used to shift hydraulic flow in automated circuits. It is built in NG10 size, so the mounting interface matches standard 10 mm port spacing. Electro-hydraulic actuation allows a small pilot stage to shift the main spool, reducing the force demanded from control electronics. The unit carries spool symbol G and provides three discrete spool positions to route pressure, tank, and actuator lines as required. A high-power 6E pilot control valve supplies the pilot oil needed for fast shifting. The solenoid coil runs on 24 V DC, simplifying integration with common control panels. Design code 4X indicates the internal geometry revision used throughout the current component series. Porting follows ISO 4401-05-05-0-05, ensuring compatibility with sub-plates and manifolds that share this pattern.
The valve passes up to 160 l/min, permitting high cylinder or motor speeds without excessive pressure loss. System safety is upheld by a 280 bar rating on the P, A, and B ports, while pilot passages tolerate up to 250 bar. A spring-centered return needs at least 12 bar pilot pressure to shift the spool reliably. A concealed N9 manual override lets technicians reposition the spool during commissioning or power loss without exposing the mechanism to contaminants. Oil cleanliness must meet ISO 4406 20/18/15, limiting particle content to protect the precision fit between spool and housing. The mean time to dangerous failure is 100 years, reflecting the durability of the WEH design in continuous service.
