Product Overview
The Rexroth 4WRPH10E4B100L-20/G24Z4/M (Material Number: 0811404061) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth WRPH series. Engineered for precise electro-hydraulic control of flow direction and magnitude, this valve utilizes a proportional solenoid on a pilot stage to actuate the main spool, delivering infinitely variable flow control proportional to the input current. With a size 10 (NG10) nominal footprint and a flow capacity of 100 L/min at a 10 bar pressure drop per land, it serves as a critical control element in demanding industrial systems requiring fast response, high repeatability, and smooth dynamic performance. The integrated Z4 designates a spool position feedback option, while the G24 indicates a 24 V DC solenoid supply. This valve is the definitive choice for closed-loop position, velocity, and force control applications in modern hydraulic machinery.
