The Bosch Rexroth 4WE10G4X/CW110RN9DA/V (R978909773) is a high-performance directional spool valve, integral to controlling the start, stop, and direction of fluid flow within hydraulic systems. This model features a robust housing that contains one or two wet-pin AC solenoids, a control spool, and return springs. The solenoids are designed to actuate the control spool from its rest position to the desired end position, effectively managing the flow from P to A and B to T or P to B and A to T. The valve is equipped with manual override capabilities that allow for manual operation in the absence of solenoid energization. It also includes a throttle insert option for increasing flow resistance in specific channels under certain operating conditions that may exceed the valve's performance limit. The 4WE10G4X/CW110RN9DA/V is engineered without spring return in its default state, meaning it does not have a defined basic position when deenergized—unless it is equipped with detent (OF version), which locks the control spool in place for energy-efficient operation by eliminating the need for continuous current. This particular model boasts compatibility with porting patterns according to ISO standards and features high-power solenoid technology. The solenoid coil of this valve can rotate by 90 degrees and can be swapped out without opening the pressure-tight chamber, providing ease of maintenance and flexibility. Additionally, electrical connections can be made either as individual connections or through a central connection, with an optional auxiliary operating device available for enhanced functionality. It's important to note that when using valves with detents, separate return lines or check valves in tank lines are recommended due to potential pressure peaks that could cause unintended movements of the control spool. This model offers reliable performance in various hydraulic applications where precise flow direction control is required.
