Product Overview
The Rexroth 4WRZE 10 W6-85-73/6EG24N9EK31/F1D3M (Material Number R900961306) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series. It is designed to control the direction and magnitude of flow in hydraulic systems proportionally to an electrical input signal, enabling precise, stepless velocity and position control of actuators. The valve features a size 10 (NG10) main stage with a nominal flow of 85 L/min at a 73 bar pressure differential across the valve, and is actuated by a single proportional solenoid with integrated position feedback for closed-loop control accuracy. The 4WRZE series is widely regarded as a benchmark for electro-hydraulic proportional control in demanding industrial environments.
