Bosch Rexroth 4WE6D51/AG24N9K4V is a solenoid‑operated four‑way, two‑position hydraulic directional valve from the WE6 family. This direct‑operated spool valve uses a 24 V coil (AG24) to shift flow between ports, enabling bidirectional actuation of a double‑acting hydraulic cylinder. Designed for robust industrial hydraulics, it provides reliable on/off control with fast switching and is offered in Rexroth's standard cavity/port configurations for subplate or manifold mounting; the 4WE6D51 designation identifies the size and flow characteristics within the class, while AG24 denotes the coil voltage for actuation.
