The Bosch Rexroth 4WE 6 C6X/EG96K4 SO9 (R978035089) is a high-performance directional control valve designed for managing the flow and direction of hydraulic fluid within a system. This solenoid-operated directional spool valve is essential for starting, stopping, and directing fluid flow with precision. It features a robust housing that encases two electromagnets, the control spool, and return springs which ensure the valve's reliability in maintaining its default position when de-energized. The 4WE 6 C6X/EG96K4 SO9 model is versatile, with manual override capabilities through an auxiliary actuation feature that allows manual operation in the absence of power to the electromagnets. This specific model lacks spring return in the control spool, meaning it does not have a predefined resting position when not powered. However, it can be equipped with detents for fixed positioning in its switching states, promoting energy efficiency by eliminating the need for continuous power supply to maintain its position. This valve variant offers soft switching behavior that minimizes hydraulic shock during operation by significantly reducing switching strokes and associated acceleration values. The porting pattern of this model adheres to ISO standards and includes options for high-power solenoids that can be rotated if necessary. Electrical connections can be made either individually or via central connection points. Additional features include optional spool position monitoring and compliance with CE conformity standards for electrical voltages above specified thresholds. The solenoid coil comes with an UR marking as per UL specifications and can also be outfitted to meet CSA approval requirements. Users must note that separate drain lines or check valves are recommended to avoid unintentional spool movements caused by pressure peaks when using versions with detents due to internal leakage that may increase over time. Furthermore, a throttle insert may be necessary under certain operating conditions to manage flows that exceed the valve's performance limit during switching processes.
