The 4WE6G6X/EG24N9K4SO43A-1755 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow between actuator ports in automated machinery. Nominal size 6 defines its compact envelope, while an ISO 4401-03-02-0-05 porting pattern and NFPA D03 mounting face enable straightforward subplate installation. The solenoid operates at a rated voltage of 24 V DC and draws 1.25 A, integrating with standard control supplies. Class F coil insulation tolerates higher winding temperatures, and the permitted coil surface temperature reaches 120 °C before de-rating is required. Electrical hookup uses a DIN EN 175301-803 K4 connector that secures with a central screw for reliable contact.
The valve supports a maximum flow of 80 l/min during direct-current actuation and allows operating pressures to 350 bar at ports P, A, and B, while the tank port is limited to 210 bar. Hydraulic fluid must meet ISO 4406 20/18/15 cleanliness to prevent spool wear. An IP65 ingress rating protects the enclosure against dust and water jets when the connector is properly sealed. A concealed manual override identified as N9 permits mechanical actuation without exposing moving parts. The coil circuit withstands switch-off overvoltages up to 500 V, minimizing the risk of insulation damage. A mean time to dangerous failure of 300 years supports long-term reliability in safety-related hydraulic loops.
