Bosch Rexroth 4WE6E51 AG24 N9K4V Solenoid Valve

Bosch Rexroth 4WE6E51 AG24 N9K4V is a solenoid‑operated four‑way hydraulic directional valve used to route fluid and control the motion of a double‑acting cylinder in hydraulic systems. It is driven by a 24 V DC coil (AG24) and belongs to Rexroth’s 4WE6 series, a compact direct‑acting valve family designed for reliable electrical actuation in industrial machinery. The 4WE6E51 code identifies the valve size/configuration, while the N9K4V suffix denotes the electrical variant for this exact model. In operation, energizing the valve shifts the spool to connect the appropriate ports, enabling extend or retract actions, with the neutral position returning as configured in the valve’s standard pattern. The valve is designed to fit standard Rexroth porting and mechanical patterns, facilitating mounting on compatible manifolds or subplates and enabling straightforward integration into existing control architectures. Typical applications include actuation of double‑acting cylinders in automation lines, presses, or machine tools where dependable 24 V control signals are available and reliable directional control is required.
