Product Overview
The Rexroth 4WRA 6 V30-22/CG24N9K4/V-589 (part number 0811404123) is a direct-operated, proportional directional valve from the renowned Rexroth 4WRA series. Engineered for precise control of flow direction and magnitude in hydraulic systems, this valve utilizes a proportional solenoid on each end of a spring-centered spool to deliver infinitely variable metering positions. The 4WRA series is a proven workhorse in industrial hydraulics, offering excellent dynamic response, low hysteresis, and reliable performance in demanding applications where accurate velocity and position control of actuators is required. With a size 6 (NG6 / CETOP 3) interface, this valve is designed for direct manifold mounting and is compatible with a wide range of mineral oils and hydraulic fluids.
