Bosch Rexroth 4WE6J51 AG24NK4 Solenoid Valve

The Bosch Rexroth 4WE6J51 AG24NK4 is a size-6, four-way, two-position solenoid-operated directional valve in the Rexroth WE6 family, engineered for precise hydraulic control in industrial equipment. This 4/2 valve uses a dual-solenoid (J) configuration to switch fluid between the P–T supply and the A–B work ports, and it mounts to standard ISO 4401-03-02 patterns for easy integration into prebuilt manifolds. The valve features high-power solenoids with a detachable coil and a 24 V DC coil voltage (AG24NK4 family), with the option for 90° rotation to suit tight installations. Porting follows the ISO 4401-03-02-0-05 pattern, enabling consistent connections across Rexroth’s modular valve platforms and multiple circuit configurations. Optional features include spool-position monitoring and CE conformity; the solenoid coil may carry UL UR markings where applicable. Typical applications include actuating hydraulic cylinders or motors in automation, clamping, lifting, and material-handling systems, where reliable, fast directional control is required and space constraints call for compact, standard-pattern valves.
