The Bosch Rexroth 4WE 6 D6X/EG24N9K40/B10 SO859 (R901185264) 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 an essential component for various hydraulic applications, offering precise control over start, stop, and flow direction. The robust construction includes a housing, one or two electromagnets, a control spool, and return springs. This particular model features two switching positions with two high-power solenoids that can be optionally rotated by 90 degrees to accommodate different installation requirements. The electric connection can be configured as either a single or central connection based on the specific application needs. For manual operation without magnet supply, an auxiliary actuation mechanism is provided. Designed with versatility in mind, this valve supports porting patterns according to ISO standard with options for including or omitting a locating hole. It also offers optional spool position monitoring to ensure operational accuracy and safety. For systems requiring compliance with electrical safety standards, the solenoid coil comes with CE conformity according to the Low-Voltage Directive EU for electrical voltages greater than 50 VAC or 75 VDC and has an approved component marking (UR) according to UL standard edition, as well as optional CSA approval. The Bosch Rexroth 4WE 6 D6X/EG24N9K40/B10 SO859 valve is engineered for durability and energy efficiency; versions with detent allow for fixed positioning of the control spool without continuous current supply to the electromagnet. However, it's important to note that pressure peaks in the drain line may cause unintended control spool movements in these versions; separate return lines or check valves are recommended to mitigate this risk. While designed to minimize internal leakage, users should be aware that leakage can increase over the product's lifespan. Additionally, throttle inserts may be required under certain operating conditions where flows exceed the performance limit during switching processes.
