The Bosch Rexroth 4WE10D5X/EW120N9K4/M (R901483527) is a high-performance directional spool valve designed for controlling the start, stop, and direction of flow within hydraulic systems. This model features a robust housing, two high-power electronic solenoids, a control spool, and return springs that maintain the spool in its central or initial position when de-energized. The wet-pin electronic solenoids enable precise movement of the control spool to achieve desired flow directions upon energization and return it to its resting state once power is cut off. This particular valve also includes a manual override function that allows operators to manually switch the valve in the absence of electrical power. It is important to note that for optimal operation, the pressure chamber should be filled with oil. The unit can be equipped with a throttle insert in channels P, A, B or T for increased flow resistance under certain operating conditions. The 4WE10D5X/EW120N9K4/M valve comes without spring return in its default configuration but has options for detent (OF) which locks the control spool in position and reduces the need for continuous current application for energy efficiency. However, it is recommended to use separate return lines or install a check valve to avoid unwanted movements due to pressure peaks when using valves with detent. This directional valve can be configured as 3 or 4-way versions with porting patterns according to ISO standards. It features an electric connection that can be individually or centrally connected and is suitable for use with PWM connectors or fast-switching amplifiers for enhanced performance. Additionally, this model meets CE conformity requirements according to the Low-Voltage Directive EC for electrical voltages above specified thresholds and includes solenoid coils approved by UR and optionally by CSA C22.2 No. 139 standards.
