The 4WE6L6X/EG24N9DK35L valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to shift flow paths in hydraulic automation systems. Its porting pattern conforms to ISO 4401-03-02-0-05, allowing direct installation on standard subplates, while the NFPA mounting size D03 matches common manifold footprints. The valve tolerates 350 bar on ports P, A, and B so it can operate in high-pressure circuits, and the tank port withstands 210 bar to handle elevated return pressures. Maximum flow under direct-current actuation reaches 80 l/min, covering medium flow demands. A nominal supply of 24 V DC powers the solenoid, with a ±10 % voltage window to keep performance stable when supply levels vary. At rated voltage the coil draws 1.25 A, giving designers a fixed current figure for power budgeting.
The electrical load is defined by a nominal power of 30 W, and a 100 % duty cycle allows the solenoid to remain energized continuously without forced cooling. Coil surface temperature is limited to 120 °C to protect windings that use insulation class F materials. An IP65 protection rating seals the enclosure against dust ingress and low-pressure water jets, making the valve suitable for exposed machine areas. Fluid cleanliness must meet ISO 4406 20/18/15 so the spool can shift reliably without sticking, and NBR seals provide compatibility with customary mineral hydraulic oils. The valve can switch up to once per second in the DK35L damping configuration, supporting moderate cycling tasks in automated equipment.
