Product Overview
The Rexroth 4WRSE 10V80-32/G24K0/A1V (Material Number: R900579286) is a high-performance, direct-operated proportional directional valve designed for precise control of flow direction and magnitude in industrial hydraulic systems. Featuring a size 10 (NG10) nominal footprint, this valve utilizes a robust proportional solenoid on one end and a spring return mechanism on the opposite end to achieve infinitely variable spool positioning. The “V80” designation indicates a nominal flow capacity of 80 L/min at a 10 bar (145 psi) pressure drop per metering edge, making it ideal for applications requiring smooth acceleration and deceleration profiles. The integrated “A1V” spool type provides a specific flow characteristic (typically progressive or linear) tailored for sensitive velocity control. As a critical component in modern electro-hydraulic control loops, this valve interfaces seamlessly with Rexroth proportional amplifiers and control electronics to deliver repeatable, high-resolution actuation for demanding motion control tasks.
