The Bosch Rexroth 4WE10L5X/EW120N9K4/M (R901487104) is a high-performance directional spool valve designed for controlling the start, stop, and direction of fluid flow within a hydraulic system. This valve is characterized by its robust housing, electronic solenoids, control spool, and return springs, which work together to ensure reliable operation under various conditions. The valve features manual override capabilities that allow for manual actuation in the absence of solenoid energization. Equipped with wet-pin electronic solenoids, the 4WE10L5X/EW120N9K4/M ensures smooth and precise movement of the control spool from its rest position to the desired end position, thereby allowing for controlled flow direction as per the selected symbol. Once the solenoid is de-energized, the control spool returns to its central or initial position unless it's a version with OF detent or without type O spring. This model includes throttle inserts that can be used in channels P, A, B, or T to increase flow resistance when necessary due to operating conditions that exceed the valve's performance limit. The valve is designed without spring return in its basic version (O), meaning it does not have a defined basic position when de-energized. However, there are versions with OF detent (with spring return) that lock the control spool in place during operation for energy-efficient use. The 4WE10L5X/EW120N9K4/M conforms to ISO porting pattern standards and features high-power solenoids which can be optionally rotated by 90 degrees. Electrical connections can be made individually or centrally and are compatible with PWM connectors for fast switching amplifiers and energy reduction. The unit also meets CE conformity requirements according to EC Low-Voltage Directive for electrical voltages greater than 50 VAC or 75 VDC and includes a solenoid coil with UR approval as well as an optional CSA C22.2 No. 0 approval. This versatile directional valve is suitable for various hydraulic applications requiring precise flow control and offers configurations suitable for different operational needs including those requiring continuous current application avoidance or specific locking positions during use.
