Product Overview
The Rexroth 4WRPEH10C3B50L-20/G24K0/F1M (Material Number: 0811404819) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth 4WRPEH series. Engineered for precise electro-hydraulic control of flow direction and magnitude, this valve features integrated digital on-board electronics (OBE) with a ±10 V or 4–20 mA command interface. The “C3” spool type provides a critical-center, overlapped configuration optimized for position and velocity control in demanding closed-loop systems. With a nominal flow capacity of 50 L/min at Δp = 10 bar per land and a maximum operating pressure of 350 bar, this valve delivers exceptional dynamic response, minimal hysteresis, and superior repeatability. Its robust design and precise metering characteristics make it the preferred choice for high-performance industrial applications requiring accurate motion control, pressure regulation, and energy-efficient operation.
