Product Overview
The Rexroth 4WRPH10C3B50L-20/G24Z4/M (Material Number: 0811404058) is a high-response, pilot-operated proportional directional valve from the Bosch Rexroth WRPH series, engineered for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 10 (NG10) nominal footprint, this valve utilizes a proportional solenoid on the pilot stage to position a main spool via hydraulic pilot pressure, delivering fast, repeatable response with minimal hysteresis. The “C3” spool design provides a specific flow metering characteristic suited to position, velocity, and force control loops, while the integrated spring-centered design ensures a defined fail-safe neutral position when de-energized. With a rated flow of 50 L/min at Δp = 10 bar per land and a G24 (24 V DC) solenoid with Z4 (central connector) electrical interface, this valve is a direct-fit solution for high-cycle industrial applications requiring accurate electro-hydraulic actuation.
