The Bosch Rexroth 4WE6D6X/EG24N9DK24L2/B10/62 (R978908789) is a high-performance directional spool valve designed for controlling the flow and direction of hydraulic fluid within a system. This model is solenoid-operated, featuring two electromagnets without detent, meaning it does not maintain a fixed position when de-energized. The valve operates with a 4-way configuration and conforms to ISO porting patterns, which can include an optional locating hole for installation ease. Capable of manual operation via an auxiliary actuation device, this Bosch Rexroth valve offers flexibility in control even without electrical power. It has been engineered to exhibit soft switching behavior, significantly reducing the number of switching strokes and potential acceleration values during operation. This contributes to smoother transitions and reduced system wear. For enhanced performance customization, the 4WE6D6X/EG24N9DK24L2/B10/62 valve can be fitted with a throttle insert if operating conditions exceed the valve's performance limits during switching processes. The high-power solenoid of this model can be rotated for optimal alignment with system requirements, and electrical connections are available as either single or central connections. Monitoring of the spool position is optional for this model, providing additional operational insights when required. The valve also meets CE conformity standards for electrical voltages above certain thresholds and includes solenoid coils that have been approved with UR marking according to UL standards. Additionally, there is an optional CSA approval available. Notably, this directional valve may experience internal leakage over its service life—a common characteristic due to its design principle. Users are advised to properly vent hydraulic systems and consider separate return lines or check valves in certain configurations to prevent unintended control spool movements in applications where pressure peaks could occur in the drain line.
