The Bosch Rexroth 4WE10C5X/EW120N9K4/M (R901487112) is a high-performance directional spool valve designed for controlling the start, stop, and direction of fluid flow within a hydraulic system. This model features a housing, one or two electronic solenoids, a control spool, and return springs. The valve operates by shifting the control spool from its neutral position to an actuated position when the solenoid is energized, thereby allowing fluid to flow in the desired direction. The valve is equipped with manual override capabilities that allow for manual operation in the absence of solenoid power. It is important that the solenoid pressure chamber is filled with oil to ensure correct operation. The 4WE10C5X/EW120N9K4/M comes with throttle inserts which can be used in various channels to increase flow resistance and adapt to different operating conditions. This specific model does not have spring return in its default configuration; therefore, it does not return to a central position when de-energized unless configured with an OF detent option. With this detent feature, the control spool can be locked into position without continuous current application, which enhances energy efficiency. Key specifications include compatibility with ISO porting patterns and high-power solenoids that can be optionally rotated by 90 degrees. Electrical connections are available as individual or central connections and may include options such as PWM connectors for fast switching amplifiers or energy reduction circuits. The valve also meets CE conformity standards for electrical voltages greater than 50 VAC or 75 VDC and features solenoid coils with UR approval as well as optional UL approval according to CSA C22.2 No. 0-M91. In summary, this Bosch Rexroth directional valve offers robust performance and versatility for hydraulic applications requiring precise control of fluid dynamics while prioritizing energy efficiency and operational reliability.
