The 4WE6D6X/EG24N9K4/62SO888 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for switching hydraulic flow paths in automation systems. It follows the NFPA T3.5.1 D03 mounting pattern so the body aligns with standard subplates, while the ISO 4401-03-02-0-05 porting pattern positions the pressure, tank, and work ports precisely for leak-free manifold assembly. A 24 V DC solenoid drives the spool, and the ±10 % voltage tolerance keeps operation stable when the supply varies. Electrical demand stays modest because the coil draws a nominal 30 W, and a 100 % ED duty cycle lets the solenoid remain energized continuously without overheating. The DIN EN 175301-803 (K4) connector offers a quick-disconnect interface, and an IP65 rating at the connector prevents dust ingress and low-pressure water jets from reaching the contacts.
The hydraulic circuit can run at up to 350 bar on pressure and work ports, while the tank port is limited to 210 bar, letting the valve fit medium-to-high pressure systems. Flow capacity reaches 80 l/min in direct-current operation to support actuators that require moderate volume. During coil de-energization, a switch-off overvoltage of up to 500 V may occur, so downstream electronics must be rated accordingly. The coil surface may reach 120 °C under continuous load, a figure used to verify insulation class and surrounding material limits. A concealed manual override identified as N9 allows local actuation when electrical power is absent yet shields the pin from accidental operation. Positioning in the manifold is secured by a locating hole that accepts a locking pin ISO 8752-3×8, preventing rotation or axial movement under vibration.
