Bosch Rexroth 4WE10E21 AW110NZ4 5V Hydraulic Valve

Bosch Rexroth 4WE10E21 AW110NZ4 5V is a solenoid-operated four-way directional valve in Rexroth’s compact 4WE series, designed for tight hydraulic circuits. With nominal size 10 (the 4WE10 designation) and two-position actuation, it directs flow from the pressure port to either work port A or work port B while the opposing work port is routed to the tank, enabling precise control of a double‑acting actuator. The valve operates from a 5 V direct-current coil, supporting integration with low‑voltage control logic in automated equipment. Its small footprint combined with the rugged Rexroth build quality makes it suitable for machine tools, automation cells, clamping tasks, and other applications where space is at a premium but reliable directional control is required. Common use cases include actuating simple cylinder moves, selecting hydraulic paths within compact manifolds, and retrofit projects where a like-for-like Rexroth 4WE10 valve is desired alongside existing control elements. The 4WE10 family is known for robust performance in industrial hydraulics, offering standard mounting interfaces and compatibility with Rexroth valve patterns and materials designed for mineral oil–based hydraulic fluids in auxiliary and primary circuits.
