The 4WE6J73-6X/EW110RN9DK25L/A12 CSA directional spool valve is built by Bosch Rexroth as part of the WE Directional Spool Valves series for controlling hydraulic actuators in industrial automation systems. Its nominal size 6 establishes the internal flow section required for compact manifolds, while the ISO 4401-03-02-0-05 porting pattern matches common subplates to simplify installation. The valve endures line pressures up to 350 bar at ports P, A, and B, whereas return flow at port T is limited to 160 bar to protect tank lines. A maximum flow of 60 l/min supports medium-duty cylinder or motor speeds without excessive pressure drop. The wet-armature solenoid is energized with 110 V at 50 or 60 Hz and draws 0.34 A during steady conduction; an inrush demand of 220 VA supplies the magnetic force needed to shift the spool quickly.
After actuation the power requirement falls to a holding value of 50 VA, reducing heat generation in continuous service. A duty cycle of 100 % ED lets the coil remain energized indefinitely, and insulation class H materials permit winding temperatures up to 120 °C without loss of dielectric strength. The DK25L five-pole plug provides a secure electrical connection that supports quick replacement during maintenance. An IP65 enclosure rating keeps dust and low-pressure water jets from entering the solenoid housing when the gasketed connector is fitted. For commissioning or emergency operation, a concealed N9 manual override allows the spool to be shifted with a tool while preventing accidental use. These features maintain reliable valve performance in harsh plant environments and ensure compatibility with standard control cabinets.
