The Bosch Rexroth 4WE 6 D6X/OFEG12N9DA/V/62 (R978892369) is a high-precision directional control valve designed for hydraulic systems requiring the control of fluid direction and flow. This model operates as a solenoid-operated directional spool valve, integral in starting, stopping, and directing flow within a hydraulic circuit. It features two solenoid electromagnets without detent, meaning the control spool does not have a fixed basic position when de-energized and requires electrical power to maintain its position. Constructed with a robust housing, the valve includes a control spool that shifts between positions under electromagnetic force, facilitated by the solenoids. Return springs are used to revert the spool to its neutral position once the solenoid is de-energized; however, this particular model does not incorporate spring return on the control spool. For manual override in situations where there is no power supply to the electromagnets, an auxiliary actuation feature is included. The 4WE 6 D6X/OFEG12N9DA/V/62 is engineered for reliable operation with an optional throttle insert for scenarios where operating conditions generate flows exceeding the valve’s performance limit during switching processes. It adheres to ISO porting patterns with options for locating holes and offers flexibility with high-power solenoids that can be rotated by 90 degrees. Electrical connections are versatile, allowing for single or central connections. For safety and compliance purposes, this model conforms to CE standards relevant to low-voltage directives for electrical voltages greater than 50 VAC or 75 VDC. Additionally, it has options for solenoid coils with UR marking according to UL standards and CSA approval. The design ensures efficient energy use by eliminating the need for continuous current supply when equipped with detents that hold the control spool in position during operation. However, users must be cautious of pressure peaks which may inadvertently cause unintended spool movements in versions with detent; separate return lines or check valves in drain lines are recommended solutions. Despite being subject to internal leakage by design principle, this valve remains a reliable component in hydraulic systems where precision flow direction is critical.
