Product Overview
The Rexroth R900840587 is a high-performance proportional directional valve from the renowned Bosch Rexroth WRZ series, engineered for precise, infinitely variable control of flow direction and magnitude in industrial hydraulic systems. Utilizing a robust spool-and-sleeve design actuated by a high-force proportional solenoid, this valve translates an electrical current signal into a proportional hydraulic output, enabling smooth, stepless control of actuator speed, position, and force. As a critical interface component in modern electro-hydraulic control loops, the R900840587 is designed for demanding applications requiring fast response, excellent repeatability, and low hysteresis. Its direct-operated, spring-centered configuration ensures a defined fail-safe mid-position, making it an ideal choice for high-cycle industrial machinery where reliability and precise motion control are paramount.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool is directly positioned by the proportional solenoid, providing infinitely variable flow control with minimal hysteresis and excellent repeatability for accurate velocity and position regulation of hydraulic actuators.
- Fast Dynamic Response: Optimized spool geometry and high-force solenoid design deliver rapid response times, essential for high-cycle industrial applications and closed-loop control systems.
- Fail-Safe Spring Centering: In the event of power loss or signal failure, the integrated centering spring automatically returns the spool to its defined mid-position, ensuring safe system shutdown and preventing uncontrolled actuator movement.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust housing and precision-machined spool and sleeve for long service life and minimal internal leakage.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring seamless integration into existing hydraulic manifolds and control systems.
Typical Industrial Applications
The Rexroth R900840587 proportional directional valve is widely deployed in demanding industrial environments, including plastic injection molding machines for precise injection and clamping control, metallurgical presses for accurate force and position regulation, CNC machine tools for smooth axis movement, and general construction and marine hydraulics where reliable, proportional motion control is critical for operational efficiency and safety.
