The Bosch Rexroth 4WE6D6X/EW110N9DK25LSO779 (R900945536) is a high-performance directional spool valve designed to control the start, stop, and direction of fluid flow within a hydraulic system. This model features two switching positions and is operated by two electromagnets without a spring return, meaning it does not have a defined basic position when de-energized. It also includes an auxiliary actuation for manual switching without magnet supply. The valve's housing, electromagnets, control spool, and return springs are constructed to ensure reliable operation and ease of maintenance. The design allows for soft switching behavior, reducing the number of switching strokes and potential system shock when engaging or disengaging the valve. This model adheres to ISO porting pattern standards and offers options for port configurations with or without locating holes. Equipped with high-power solenoids that can be rotated by 90 degrees for flexible installation, the 4WE6D6X/EW110N9DK25LSO779 also provides electric connections as either single or central connections. For safety and compliance, it meets CE conformity according to the Low-Voltage Directive EU for electrical voltages greater than 50 VAC or 75 VDC. Additionally, the solenoid coil comes with an approved UR marking according to UL standard edition, with an optional approval according to CSA C22.2 No. 139. This directional valve is suitable for various hydraulic applications where precise control of fluid flow is required. It offers energy-efficient operation through its detent version that allows for fixed positioning of the control spool without continuous current supply. However, it's important to note that separate return lines or check valves may be necessary due to pressure peaks in drain lines that could cause unintended spool movements in versions with detent. Lastly, the model may require a throttle insert under certain operating conditions where flow during switching processes exceeds performance limits of the valve. This ensures optimized performance and longevity of the valve within complex hydraulic systems.
