The 4WE6D6X/OFEW110DK25L/62 directional spool valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for controlling actuator movement in hydraulic automation. It is built in nominal size 6, allowing it to mount in compact blocks without excessive pressure loss, and follows the ISO 4401-03-02-0-05 porting pattern so manifold drilling remains standardized. A DK25L five-pole plug handles the electrical connection, providing quick removal during service. The solenoid is rated for 110 V AC at 50/60 Hz, and under 50 Hz supply it draws 0.52 A to create the magnetic force that shifts the spool. Hydraulic capability includes a continuous flow of 60 l/min, a pressure limit of 350 bar at ports P, A, and B, and 160 bar at the tank port so return lines remain protected. These limits define how the valve supports medium-power circuits without cavitation or leakage.
The valve operates in ambient temperatures up to 50 °C, enabling installation near heat-producing machinery. Fluid entering the unit must meet ISO 4406 cleanliness class 20/18/15, which safeguards the precision spool fit against scoring. An IP65 enclosure stops dust ingress and low-pressure water jets, while insulation class H windings allow coil temperatures that would damage lower-grade materials. The coil surface may reach 120 °C during prolonged energization without compromising integrity, and at 60 Hz supply the current falls to 0.39 A, reducing thermal loading in regions using that frequency. The design withstands 500 V switch-off overvoltage, protecting upstream control electronics when the field collapses. With both solenoids installed the assembly weighs 1.95 kg, so it can be handled with one hand during manifold maintenance.
