The Bosch Rexroth 4WE10Y5X/EW120N9K4/M (R901487103) is a high-performance solenoid-actuated directional spool valve designed to control the start, stop, and direction of fluid flow in hydraulic systems. This model features a robust housing, one or two high-power solenoids, a control spool, and return springs that ensure reliable operation in various applications. The valve operates by moving the control spool from its central or initial position to an end position when the wet-pin electronic solenoid is energized, allowing for precise flow direction as per the selected symbol. Equipped with manual override capabilities, this valve can be manually actuated in the absence of solenoid power. It is important to maintain oil within the pressure chamber of the solenoid for optimal functionality. The inclusion of a throttle insert (Type B) enables adjustment of flow resistance at channels P, A, B, or T to accommodate different operating conditions and prevent flows that exceed the valve's performance limit during switching processes. This particular model is available without spring return (Type O), suitable for symbols A, C, and D configurations and without spring return but with detent (Type OF), also compatible with symbols A, C, and D. Detents are incorporated to lock the control spool in place during operation for energy-efficient usage without requiring continuous current. The Bosch Rexroth 4WE10Y5X/EW120N9K4/M valve features porting patterns according to ISO standards and offers options such as electrical connections for individual or central connections and use with PWM connector fast switching amplifiers. It has CE conformity per Low Voltage Directive EC for voltages greater than 50 VAC or 75 VDC and includes a solenoid coil with UR approval UL. Additionally, it holds an approval according to CSA C22.2 No., optional for certain configurations. This versatile directional valve is designed for both 3-way or 4-way configurations ensuring adaptability across various hydraulic system requirements.
