Product Overview
The Rexroth STW0322-10/3WRCE50V720L-SG24K31C1M (Material Number: R901147272) is a high-performance proportional directional control valve engineered for precise, infinitely variable control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a 4-way, 3-position spool design with integrated position feedback, this valve operates on the principle of proportional solenoid actuation, where electrical input signals are translated into proportional spool displacement, enabling accurate metering of hydraulic fluid. The “WRCE” designation indicates a pilot-operated, high-response proportional valve with electrical position feedback and integrated control electronics, ensuring exceptional dynamic response and repeatability. As a core component within Rexroth’s renowned proportional and servo valve portfolio, the STW0322-10 series is designed for closed-loop control applications where precise velocity, position, and force regulation are critical to overall system performance and energy efficiency.

Engineering Features & Advantages
- Precision Proportional Metering: The valve spool is infinitely positioned via proportional solenoids, allowing exact, repeatable control of flow rate and direction proportional to the electrical command signal, essential for accurate velocity and position control in closed-loop systems.
- Integrated Position Feedback: The SG24K31C1M configuration includes an electrical position feedback sensor that continuously monitors spool position, ensuring high hysteresis accuracy, excellent repeatability, and minimal response delay even under varying pressure and flow conditions.
- High Dynamic Response: Designed for fast step responses and high-frequency command tracking, making it ideal for applications requiring rapid acceleration and deceleration of hydraulic actuators without sacrificing stability.
- Robust Industrial Construction: Manufactured to Rexroth’s stringent quality standards with hardened, precision-ground spool and sleeve assemblies, providing long service life and reliable operation in harsh industrial environments.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
