The 4WE6D6X/EG24N4K4 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow paths in automated power units and accepts a 24 V DC supply; under this voltage it draws a rated current of 1.25 A and consumes 30 W of coil power to generate the magnet force needed for spool movement. The unit operates at 100 % duty so continuous energizing will not cause thermal overload. Electrical hookup is through a K4 connector conforming to DIN EN 175301-803, and Class F insulation separates the winding from the housing to withstand elevated temperatures. A ±10 % voltage tolerance permits reliable actuation despite supply fluctuations, while the coil surface may reach 120 °C without degrading materials. The enclosure attains IP65 protection against dust and water jets, and a lockable mushroom-style manual override designated N4 allows mechanical shifting when power is absent.
The valve mounts on an NFPA D03 sub-plate, matching the ISO 4401-03-02-0-05 porting pattern so circuit designers can exchange units without altering manifold blocks. It accommodates a maximum flow of 80 l/min, enabling moderate-capacity actuators to operate at full speed, and withstands 350 bar on ports A, B, and P to suit high-pressure industrial hydraulic systems. Tank return pressure may reach 210 bar, supporting circuits where back-pressure controls deceleration or counterbalance loads. A switch-off overvoltage limit of 500 V protects the coil and upstream electronics when the driver releases current, preventing arcing at contacts. These hydraulic and electrical limits combine to provide consistent, repeatable spool positioning across continuous service cycles.
