Product Overview
The Rexroth 4WRSE 10 V50-32/G24K0/A1V (Material Number: R900579943) is a high-response, two-stage proportional directional valve manufactured by Bosch Rexroth. It is engineered for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. The valve operates on a pilot-operated principle: a high-performance proportional solenoid actuates a pilot spool, which in turn controls the main stage spool via hydraulic pressure. This two-stage architecture delivers fast dynamic response, minimal hysteresis, and excellent repeatability, making it ideal for closed-loop position, velocity, and force control applications. The integrated position feedback of the main spool ensures accurate spool positioning proportional to the electrical command signal, enabling seamless integration with modern proportional amplifier cards and PLC-based control systems.
