The Bosch Rexroth 4WE6D9-6X/EG24N9K4/N15 (R900978423) is a high-performance directional valve designed for controlling the start, stop, and direction of fluid flow within a hydraulic system. This solenoid-operated directional spool valve is characterized by its robust housing, one or two electromagnets, a control spool, and return springs that ensure reliable operation. The control spool is held in a neutral position by the return springs when de-energized, except in versions without spring return (O). Upon energization of the electromagnet in oil, the control spool shifts to enable the desired flow path according to the selected symbol. Once the electromagnet is de-energized, the control spool returns to its neutral position unless it's a version with detent (OF) or without spring (O), which maintains its position for energy-efficient operation. The valve offers manual override capabilities through an auxiliary actuation feature. It is crucial that the hydraulic system be properly vented to guarantee correct functioning of this component. The 4WE6D9-6X/EG24N9K4/N15 valve comes without spring return and can be used with symbols A, C, and D for tailored applications. This model includes options such as soft switching behavior to minimize switching strokes and reduce mechanical stress during operation. Users should note that pressure peaks might cause unintended movements in valves with detent and that internal leakage inherent to this design may increase over time. Additional specifications include compatibility with ISO porting patterns, high-power solenoid options which can be rotated by 90 degrees for flexible installation, various electrical connection choices including single or central connections, optional spool position monitoring for enhanced control precision, CE conformity for certain electrical voltage requirements above specified thresholds, as well as UL and CSA approvals for adherence to safety standards.
