Product Overview
The Rexroth 4WRZE 10 W8-25-73/6EG24N9EK31/F1D3M is a high-response, pilot-operated proportional directional valve from the renowned Rexroth 4WRZE series. Engineered for precise control of flow direction and magnitude in demanding hydraulic systems, this valve utilizes a proportional solenoid actuation principle to deliver infinitely variable spool positioning. The “10” size designation indicates an NG10 (Cetop 5 / ISO 4401-05) interface, while the “W8” spool type provides a specific metering characteristic optimized for smooth acceleration and deceleration of actuators. The integrated “6EG24N9EK31” solenoid configuration denotes a 24 V DC high-performance proportional solenoid with integrated position feedback and an amplifier interface (EK31), ensuring exceptional repeatability and hysteresis performance. This valve serves as a critical control element in closed-loop systems where precise velocity, position, and force control of hydraulic cylinders or motors is paramount.
