Product Overview
The Rexroth 4WRE 10 W30-22/G24K4/V (Material Number R901012439) is a high-performance, direct-operated proportional directional valve designed for precise control of flow direction and magnitude in industrial hydraulic systems. As part of the Rexroth 4WRE series, this valve features a robust housing, a precision-machined spool, and a proportional solenoid actuator that enables infinitely variable positioning. It serves as a critical interface between electronic control signals and hydraulic power, allowing for smooth acceleration and deceleration of actuators, precise velocity control, and reliable load holding. The “W30” spool type indicates a specific flow metering characteristic, while the “G24” designation confirms a 24 V DC solenoid supply. This valve is engineered for demanding applications requiring high dynamic response and repeatability.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool is directly actuated by a proportional solenoid, providing infinitely variable flow control proportional to the input current. This enables precise velocity profiling and smooth motion control of hydraulic actuators.
- High Dynamic Response: Optimized solenoid and spool design ensures fast response times and high repeatability, essential for closed-loop position and pressure control systems.
- Robust Industrial Construction: The valve housing and internal components are manufactured to Rexroth’s stringent quality standards, ensuring long service life and reliable operation even in harsh industrial environments with high cycle rates.
- Direct Fit Replacement: Exact dimensional and functional compatibility with the original Rexroth 4WRE series, allowing for drop-in replacement without modification to existing manifolds or control systems.
- Integrated Electronics Option: The “K4” connector allows for simple integration with standard proportional amplifier cards or modern electronic control units, facilitating easy setup and calibration.
Typical Industrial Applications
This proportional directional valve is ideally suited for a wide range of heavy industrial applications requiring precise motion control. Common uses include plastic injection
