The Bosch Rexroth 3WE6A9-6X/EW110N9DK25LSO779 (R900955819) is a high-performance directional spool valve designed for controlling the start, stop, and direction of flow in hydraulic systems. This solenoid-operated valve features a robust housing, one or two electromagnets, a control spool, and return springs that ensure reliable operation in various applications. In its deenergized state, the control spool is maintained in its initial position by the return springs, except for the version O which lacks a spring return. Upon energizing the electromagnet(s), the control spool shifts to enable the desired flow direction as indicated by the selected symbol. Once the magnet is de-energized, except in versions with detent OF or without spring type O, the spool returns to its initial position. The model offers manual override capabilities through an auxiliary actuation feature that allows manual operation without power supply to the magnets. The valve's design incorporates soft switching behavior to reduce switching strokes and minimize wear during operation. It is important to note that internal leakage may occur and can increase over time due to this design principle. For efficient performance, it is advisable to use separate return lines or install check valves to prevent unintended movements caused by pressure peaks when using versions with detent. This model supports various configurations including 2-way or 3-way versions and follows ISO porting patterns with optional locating holes. It comes equipped with a high-power solenoid which can be rotated if necessary and offers electrical connections as either single or central connections. Additional features include optional spool position monitoring and CE conformity for electrical voltages above certain thresholds. The solenoid coil carries UL approval (UR marking) and an optional CSA approval. Overall, this Bosch Rexroth directional valve provides precise control over hydraulic flows with customizable options suitable for diverse operational requirements while ensuring energy-efficient operation and compliance with safety standards.
