The Bosch Rexroth 4WE10G73A5X/EG12N9K4/A12M (R901349645) is a solenoid-actuated directional spool valve designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This model features a housing, electronic solenoids, a control spool, and return springs. The valve operates by moving the control spool to direct flow when an electronic solenoid is energized and returns it to its initial position via the return springs upon de-energization. The 4WE10G73A5X/EG12N9K4/A12M is equipped with manual override capabilities allowing for manual operation without solenoid activation. It's critical for proper functioning that the pressure chamber of the solenoid is filled with oil. This particular model includes throttle inserts that can be used in P, A, B, or T channels to increase flow resistance when necessary due to operating conditions. The valve comes in various configurations including versions without spring return (O) for specific symbols (A, C, D) where there isn't a defined basic position when de-energized. There are also versions with detent (OF) that lock the control spool in position to enable energy-efficient operation by avoiding continuous current application during use. This model adheres to ISO porting patterns and features high-power solenoids that can be rotated by 90 degrees. Electrical connections can be made individually or centrally and may include options like PWM connectors or fast switching amplifiers for energy reduction. Additionally, it complies with CE conformity standards for electrical voltages greater than 50 VAC or 75 VDC and includes a solenoid coil with UR approval as well as CSA C22.2 No. 139 approval as an optional feature.
