Product Overview
The Rexroth 4WRZ10W85-A2/6A24NETZ4/D2M-960-3 (material number R971P20980) is a pilot-operated, two-stage proportional directional valve from the Bosch Rexroth 4WRZ series, designed for continuous, high-resolution control of flow direction and flow magnitude in industrial hydraulic systems. The valve utilizes a proportional solenoid pilot stage acting on a main spool, delivering infinitely variable spool positioning that is proportional to the electrical command signal. With a nominal size of NG10 (size 10) and a rated flow of 85 L/min at a 10 bar (1 MPa) valve pressure differential, this valve is engineered for precise velocity and directional control of actuators in demanding closed-loop and open-loop applications. The integrated on-board electronics (OBE) with the “A2” command interface and the “6A24” solenoid configuration allow direct connection to analog control signals, eliminating the need for external amplifier cards and simplifying system integration. The “NETZ4” designation indicates a specific spool/spring/override configuration, while “D2M” denotes the electrical connector and monitoring variant. As a genuine Rexroth proportional valve, it provides the dynamic response, repeatability, and long service life required in modern industrial hydraulics.
