The 4WE6E6X/EG24N9K4/B20V directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and shifts hydraulic flow paths in automated circuits. The solenoid coil operates on 24 V DC, allowing connection to standard machine control power. At that voltage the coil draws 1.25 A, and its electrical power requirement is 30 W, which helps planners size the supply transformer. A 100 % duty cycle permits the valve to remain energized continuously without overheating. The electrical interface is a DIN EN 175301-803 connector (K4) that supports fast field wiring. The housing is rated IP65 so dust and low-pressure water cannot enter. A concealed manual override (N9) lets technicians shift the spool during service, while switch-off transients are limited to 500 V to protect driver electronics.
The valve passes up to 80 l/min, giving adequate capacity for medium-size actuators. Operating pressure at ports P, A, and B can reach 350 bar, and the tank port withstands 210 bar, so the unit fits high-pressure mobile and industrial systems. Mounting uses the ISO 4401-03-02-0-05 porting pattern, enabling direct installation on NG6 subplates. A 2.0 mm throttle insert in port P (B20) restricts inlet flow to damp pressure surges. FKM seals resist higher temperatures and aggressive fluids, and the hydraulic medium must meet ISO 4406 20/18/15 cleanliness to avoid spool wear. With both solenoids fitted the assembly weighs 1.95 kg, a factor considered when sizing manifold supports.
