Product Overview
The Rexroth 4WRPH 10 C4 B100L-20/G24Z4/M (Material Number: R911404061) is a high-response, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. As part of the Rexroth 4WRPH series, this valve features a size 10 (NG10) nominal bore with integrated digital on-board electronics (OBE) and a spring-centered, 4-way, 3-position spool configuration. The “C4” spool type provides a specific flow characteristic optimized for high dynamic response applications, while the “B100L” designation indicates a nominal flow rate of 100 L/min at a 10 bar pressure drop per metering edge. The integrated G24Z4/M amplifier card accepts a ±10 V analog command signal and provides closed-loop position feedback via an inductive position transducer, ensuring exceptional repeatability and minimal hysteresis. This valve is engineered for applications requiring fast response times, high flow capacity, and precise velocity control of hydraulic actuators in injection molding, die-casting, and metallurgical processes.
