Product Overview
The Rexroth 4WREE 10 W50-2X/G24K31/F1V (Material No. R901013985) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WREE series, designed for precise control of flow direction and magnitude in industrial hydraulic systems. Featuring a size 10 (NG10) spool valve with integrated proportional solenoids and position feedback, this valve delivers exceptional dynamic response and repeatability. The “W50” spool type provides a specific metering characteristic optimized for smooth velocity control in both directions. With a rated flow capacity of approximately 50 L/min at Δp = 10 bar per land, the 4WREE 10 W50-2X is engineered for demanding applications requiring accurate electro-hydraulic actuation, closed-loop position, velocity, or force control. The G24K31 designation indicates a 24 V DC proportional solenoid with integrated position transducer, while the F1V suffix denotes the specific electrical connector and feedback configuration. This valve is a direct-fit, OEM-compatible component suitable for new installations and critical replacement in high-performance hydraulic systems.
