The 4WE6E6X/EG24N9K40SO859 valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series and directs pressurized fluid in automated hydraulic circuits. It mounts on subplates that follow porting pattern ISO 4401-03-02-0-05, ensuring compatibility with common CETOP 03 layouts. The unit withstands 350 bar in ports A, B, and P so it can be installed in high-pressure systems, while a rated flow of 80 l/min keeps medium-sized actuators supplied. The solenoid operates on 24 V DC, and a ±10 % voltage tolerance permits minor supply variations without malfunction. Coil power consumption is 30 W, and a 100 % ED duty cycle allows continuous energization during extended machine cycles. System oil must meet ISO 4406 cleanliness class 20/18/15 to avoid contamination-related sticking of the spool.
Electrical termination is achieved with a Deutsch K40 plug, and the connector assembly is sealed to IP69K so high-pressure wash-downs do not compromise the coil. A concealed manual override designated N9 enables manual spool shifting during commissioning or power loss. The coil surface may reach 120 °C, which requires adjacent components to tolerate elevated heat. Switching commands can be issued at up to 4.2 cycles per second, supporting rapid actuation in mobile or industrial equipment. Back-pressure at port T must stay below 210 bar to maintain reliable return flow. Class F winding insulation resists thermal aging under continuous load, and the two-solenoid configuration weighs 1.95 kg, a factor considered when sizing the manifold and mounting hardware.
