The Bosch Rexroth 4WE10D3X/CW220N9K4/V CSA (R978909785) is a high-performance directional spool valve designed for controlling the start, stop, and direction of fluid flow within a hydraulic system. This valve features a robust housing, up to two wet-pin electronic solenoids for actuation, and a control spool that is manipulated by the solenoid force. The return springs ensure the spool returns to its rest position when de-energized. Equipped with manual override capabilities, this valve allows for manual operation without solenoid power. The design includes throttle inserts in channels P, A, B, or T to manage flow resistance and adapt to varying operational conditions that may exceed the valve's performance limit. It operates without spring return in specific configurations (type WE ..O), meaning it does not default to a basic position when unpowered. For versions equipped with detents (type WE ..OF), the control spool can be locked into position, allowing for energy-efficient operation as continuous current application is unnecessary. However, it is advised to use separate tank lines or install check valves to prevent unintended control spool movements due to pressure peaks. This model of directional valve boasts compatibility with high-power solenoids and conforms to ISO porting patterns. Its AC solenoids are wet-pin type with detachable coils that can rotate by 90 degrees and be swapped without opening the pressure-tight chamber. Users have flexibility in electrical connections through individual or central connection options and can benefit from an optional auxiliary operating device for enhanced functionality.
