Product Overview
The Rexroth 4WRPH 10 C1 B100L-20/G24Z4/M (Material Number: 0811404076) is a high-response, pilot-operated proportional directional valve from the Bosch Rexroth 4WRPH series. Designed for precise, continuous control of flow direction and magnitude in industrial hydraulic systems, this valve utilizes a position-controlled pilot stage with a main spool featuring progressive flow characteristics. The integrated digital amplifier (G24Z4 configuration) with 24 V DC solenoid actuation enables fast, repeatable response to analog command signals, making it ideal for closed-loop position, velocity, and force control applications. The “B100L” designation indicates a nominal flow of 100 L/min at a 10 bar pressure drop across the valve, while the “C1” spool type provides a specific overlap and metering profile optimized for high dynamic response. This valve is a direct-fit replacement for OEM Rexroth part number 0811404076 and is engineered for demanding industrial environments requiring precise hydraulic motion control.
