The Bosch Rexroth 4WE 6 X2-6X/EG24N9K4 (R900947469) is a high-performance directional spool valve that operates as an electromagnetic component to control the start, stop, and direction of fluid flow within hydraulic systems. This valve features a robust housing, one or two electromagnets for actuation, a movable control spool, and return springs that hold the spool in its initial position when de-energized (except for certain versions without spring return). The energizing of the electromagnet shifts the spool from its rest position to enact the desired flow direction as per the symbol selected. Designed with versatility in mind, this model can be manually actuated through an auxiliary device without power supply to the magnets. It also boasts a porting pattern compliant with ISO standards and can be configured with or without a locating hole. The high-power solenoid is optionally rotatable by 90 degrees, allowing for flexible installation orientations. Electrical connections can be made via single or central connections. For applications requiring precise spool position monitoring, this option is available to ensure operational accuracy. Moreover, this valve aligns with CE conformity regulations for electrical voltages above certain thresholds and offers solenoid coils with UR marking as per UL standards edition, and optional CSA approval. Furthermore, it is important to note that proper venting of the hydraulic system is crucial for optimal functionality. The valve's design may inherently allow internal leakage which could increase over its lifespan. In configurations where detents are used to hold the spool in position without continuous electromagnet activation (contributing to energy efficiency), precautions such as separate return lines or check valves are recommended due to possible pressure peaks causing unintended spool movements. Lastly, this model may require a throttle insert when operational conditions produce flows during switching processes that exceed the valve's performance limit. With its sophisticated design and multiple configuration options, the Bosch Rexroth 4WE 6 X2-6X/EG24N9K4 directional valve provides reliable and efficient control in various hydraulic applications.
