Product Overview
The Rexroth 4WRPH 6 C3 B12L-20/G24Z4/M (Material Number: 0811404034) is a high-response, pilot-operated proportional directional valve from the Bosch Rexroth WRPH series. Designed for precise, dynamic control of flow direction and magnitude in hydraulic systems, this valve utilizes a proportional solenoid actuation principle with integrated position feedback to deliver fast, repeatable spool positioning. The 4WRPH series is engineered for applications demanding high response sensitivity, minimal hysteresis, and excellent repeatability under varying load conditions. With a nominal size of NG6 (CETOP 3 / ISO 4401-03), this valve serves as a critical control element in closed-loop and open-loop hydraulic circuits, enabling smooth acceleration and deceleration of actuators in high-cycle industrial machinery.
