Product Overview
The Rexroth 4WRA 6 W1-30-2X/G24K4/V (Material Number: R900902537) is a high-performance, direct-operated proportional directional valve designed for precise control of flow direction and magnitude in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve belongs to the 4WRA series, which is renowned for its robust construction and reliable operation. The “W1” spool designation indicates a specific flow characteristic, while the “30” size and “2X” series denote standard industrial mounting and connection patterns. Featuring a 24V DC solenoid with a “K4” electrical connection, this valve is engineered to provide smooth, continuous control of actuator speed and position, making it an essential component in demanding motion control applications.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool is directly actuated by a proportional solenoid, enabling infinitely variable control of flow volume and direction. This allows for smooth acceleration and deceleration of hydraulic actuators, reducing mechanical shock and improving system efficiency.
- High-Response Solenoid Technology: Equipped with a 24V DC wet-pin solenoid, the valve delivers fast response times and high repeatability, essential for closed-loop position and velocity control systems.
- Robust Industrial Construction: Designed for continuous operation in harsh industrial environments, the 4WRA series features a durable housing and precision-machined spool and sleeve assembly to ensure long service life and minimal internal leakage.
- Direct Fit Replacement: Manufactured to exact Bosch Rexroth OEM specifications, ensuring dimensional and functional compatibility with existing 4WRA series installations and standard ISO 4401-03 subplates.
- Optimized Spool Design: The “W1” spool provides a specific flow characteristic that is ideal for applications requiring fine metering and stable control at low flow rates.
