Product Overview
The Rexroth 4WREE10E75-3X/V/24F1 (Material Number R901572041) is a high-response, direct-operated proportional directional valve from the Bosch Rexroth 4WREE series. Engineered with a size 10 (NG10 / CETOP 5) subplate interface, this valve features integrated digital on-board electronics (OBE) with a 24 VDC supply and command value input of 0 to ±10 V. The 4WREE platform utilizes a precision-machined spool and sleeve assembly actuated by a proportional solenoid, enabling infinitely variable control of flow direction and magnitude proportional to the electrical command signal. With a nominal flow of 75 L/min at a 10 bar pressure differential per land, the valve delivers fast, repeatable response for demanding closed-loop position, velocity, and force control tasks in industrial hydraulic systems. Its spring-centered, fail-safe spool design ensures a defined mid-position in the event of power loss, making it a reliable choice for critical motion control applications.
