Bosch Rexroth 4WE6W51 AG24N 9K4 Hydraulic Directional Valve

Bosch Rexroth/Mannesmann Rexroth 4WE6W51/AG24N 9K4 is a solenoid‑operated 4‑way hydraulic directional valve that directs fluid between pump, actuators, and return lines in industrial hydraulic systems. This model sits in the 4WE6 family and employs a 24 V DC coil (AG24N9K4) to shift the internal spool between two positions, so in one state it connects P to A and T to B, and in the other it connects P to B and T to A. It is designed for reliable directional control in applications such as machine tools, presses, plastic injection molding lines, and other automated machinery requiring precise valve actuation. The 4‑port, 2‑position configuration is a hallmark of this series, enabling straightforward integration into existing hydraulic circuits with standard porting patterns consistent with Rexroth nomenclature. The valve is a product of Bosch Rexroth (formerly Mannesmann Rexroth), reflecting the long‑standing company focus on durable hydraulic control components for industrial environments. For installation, electrical connections are compatible with the AG24N9K4 coil variant noted in Rexroth catalogs, ensuring compatibility with common control hardware used in automated manufacturing environments.
