Product Overview
The Rexroth 4WRPEH 10 C3 B50L-20/G24K0/A1M (Material Number: 0811404800) is a high-response, direct-operated proportional directional valve with integrated digital electronics (OBE) and position feedback. As part of the Rexroth 4WRPEH series, this valve is engineered to deliver precise, continuous control of flow direction and magnitude in proportion to an electrical input signal. The “C3” spool design provides a specific flow characteristic optimized for position, velocity, and force control in demanding closed-loop industrial systems. With a nominal size of NG10 (Size 10) and a rated flow of 50 L/min at a 20 bar pressure drop per land, this valve serves as a critical interface between electronic control systems and hydraulic actuators, offering exceptional dynamic response, minimal hysteresis, and superior repeatability for high-precision motion control applications.
