Product Overview
The Rexroth 4WRZ 10 E85-7X/6EG24N9ETK31/F1D3M (Material No. R901048582) is a pilot-operated, two-stage proportional directional valve from the renowned Rexroth 4WRZ series. Designed for precise control of flow direction and magnitude in industrial hydraulic systems, this valve features a size 10 (NG10) main stage with integrated position feedback and a proportional solenoid pilot stage. The 4WRZ series is engineered to deliver high dynamic response, excellent repeatability, and low hysteresis, making it ideal for applications requiring accurate velocity and position control of hydraulic actuators. With a nominal flow capacity of 85 L/min at Δp = 10 bar per land, this valve serves as a critical control component in demanding industrial machinery.
