The Bosch Rexroth 4WE 10 HA4X/CG12N9DA (R978908741) is a high-functioning directional spool valve designed to manage the start, stop, and direction of fluid flow within a hydraulic system. It features a robust housing that contains one or two wet-pin electronic solenoids, a control spool, and return springs to ensure efficient operation. The control spool can be shifted from its neutral position to an active state by the force of the solenoids, directing fluid from ports P to A and B to T or vice versa. When the solenoid is de-energized, the return spring moves the spool back to its rest position. This model includes a manual override that allows for manual operation of the valve without electrical power. The valve is engineered for reliability in various applications, with the pressure chamber requiring oil filling for proper solenoid function. Additionally, it has a throttle insert option for increased flow resistance when necessary due to operating conditions. The 4WE 10 HA4X/CG12N9DA valve is available in configurations without spring return (O) and with detent (OF) options for specific applications that require or do not require a defined basic position when de-energized. The detent feature locks the control spool in place, allowing for energy-efficient operation by eliminating continuous current application. It's important to note that pressure peaks in tank lines connected to multiple valves may cause unintended movements if equipped with detents; thus, separate return lines or check valves are recommended. This directional valve supports high-power solenoid operations and conforms to ISO porting patterns. Its wet-pin AC solenoids are detachable and rotatable by 90° degrees for flexible installation. The coil can be replaced without opening the sealed chamber, ensuring maintenance simplicity. Electrical connections are versatile, offering both individual and central connection options. This model also comes with an optional auxiliary operating device. The Bosch Rexroth directional valve has a size designation and belongs to component series X and X2 with maximum operating pressures up to bar and maximum flow rates of l/min. It demonstrates Bosch Rexroth's commitment to quality and performance in hydraulic system components.
