The 4WE6J6X/EW110N9DK25L/B10V CSA valve is produced by Bosch Rexroth and belongs to the WE Directional Spool Valves series. It directs hydraulic fluid to actuators in automated machinery. The valve is built in nominal size 6, which matches the ISO 4401-03-02-0-05 mounting pattern to simplify manifold installation. A high-power wet-pin detachable coil allows quick replacement while keeping the armature immersed in oil for heat dissipation. The coil draws 0.39 A at a nominal voltage of 110 VAC on 50/60 Hz lines, providing the magnetic force needed for spool shifting. Switch-on power peaks at 220 VA, and holding power drops to 50 VA to limit continuous heat build-up. Continuous operation is supported by a 100 percent duty cycle in S1 service. A concealed manual override marked N9 lets maintenance staff move the spool without energizing the coil.
The valve handles flows up to 60 l/min while sustaining 350 bar on pressure, A, and B ports, so it suits medium-pressure circuits. Tank port C tolerates 160 bar, maintaining back-pressure capability without risking seal damage. FKM seals resist high-temperature hydraulic oils and provide chemical compatibility with modern fluids. An IP65 enclosure rating protects the electrical section against dust and water jets when the 5-pole Mini-Change connector DK25L is properly installed. The integrated throttle insert restricts port P with a 1.0 mm orifice designated B10, allowing damping of actuator motion. Pressure losses across the body are kept low to preserve efficiency at the maximum rated flow. The direct-operated spool shifts quickly, making the valve suitable for high-cycle machinery. These features give designers a compact directional control element that fits easily into automation manifolds.
