The Bosch Rexroth 4WE 6 H6X/EG24N9DA/V/62 SO43A-656-3 (R978900127) is a high-performance directional valve designed for controlling the flow and direction of hydraulic fluids within a system. This model is part of the WE series, which are solenoid-operated directional spool valves that serve as electromagnetic components in various applications. The valve features a robust housing, one or two electromagnets, a control spool, and return springs that maintain the spool in its initial position when de-energized. This specific model is equipped with two switching positions and two high-power solenoids without detent, meaning it does not have a defined rest position when not powered. It also offers flexibility in installation with an electric connection available as either single or central connection and the option for an auxiliary operating device. Additionally, spool position monitoring is available to enhance operational safety and precision. The valve's porting pattern conforms to ISO standards, with options for versions with or without a locating hole. The solenoid coil can be rotated by 90 degrees if required by the system design. For electrical safety compliance, this model meets CE conformity according to the Low-Voltage Directive EU for electrical voltages greater than 50 VAC or 75 VDC. Furthermore, it includes an optional solenoid coil with UR marking according to UL standard edition and can be approved according to CSA C22.2 No. 139 upon request. This Bosch Rexroth valve ensures energy-efficient operation through its soft switching behavior which minimizes switching strokes and associated acceleration values during on/off cycles. It should be noted that pressure peaks in the drain line might cause unintended control spool movements in versions with detent, so separate return lines or check valves are recommended. Internal leakage inherent to the valve's design may increase over its service life but is considered within operational tolerances. In summary, this Bosch Rexroth directional valve offers reliable performance for systems requiring precise control over hydraulic flow directions with energy efficiency and operational safety in mind.
