Product Overview
The Rexroth 4WREE10E1-50-23/G24K31/F1V (Material Number R900703908) is a high-response, pilot-operated proportional directional valve with integrated digital control electronics. Manufactured by Bosch Rexroth, this valve is part of the 4WREE series, which is renowned for its exceptional dynamic response, precise flow control, and robust construction. The valve operates on a proportional solenoid principle, where an electrical input signal is converted into a proportional hydraulic output, allowing for infinitely variable control of flow direction and magnitude. This makes it an ideal component for demanding industrial applications requiring precise position, velocity, or force control of hydraulic actuators. The integrated digital amplifier (OBE) ensures superior repeatability, minimal hysteresis, and simplified commissioning, positioning this valve as a critical element in advanced closed-loop hydraulic systems.
