The Bosch Rexroth 4WE 6 F6X/EW110N9DK25L/62 (R978901061) is a high-performance directional control valve designed for managing the start, stop, and direction of flow within a hydraulic system. This solenoid-operated directional spool valve is characterized by its robust housing, one or two high-power solenoids, a control spool, and return springs. It offers precise control over hydraulic flow with the option of manual actuation through an auxiliary device when electromagnetic supply is unavailable. The valve operates by shifting the control spool to the desired position when the electromagnet is energized, allowing for the selection of flow direction as per the symbol chosen. Once de-energized, return springs (except in versions without spring return) push the spool back to its neutral position. Versions without spring return maintain their last position until manually shifted or electrically actuated again. Designed for flexibility in application, this model can be configured as a 3 or 4-way version with porting patterns that adhere to ISO standards, with or without a locating hole. The solenoid can be optionally rotated by 90° to accommodate various installation requirements. For electrical connections, options include both single and central connections. Additionally, spool position monitoring can be opted for enhanced operational awareness. The valve also meets CE conformity requirements according to the Low-Voltage Directive of the EU for electrical voltages greater than 50 VAC or 75 VDC. For North American markets, it includes an optional solenoid coil with UR marking compliant with UL standard edition and CSA C22.2 approval. Notably, this Bosch Rexroth valve incorporates features aimed at reducing switching strokes and ensuring energy-efficient operation—particularly in versions equipped with soft switching behavior that diminishes acceleration values during on/off actions. However, internal leakage inherent to its design may increase over its service life—a factor users must consider in maintenance planning. Lastly, separate drain lines or check valves are recommended when using multiple valves to prevent unintended spool movements due to pressure peaks in shared drain lines.
