Product Overview
The Rexroth 4WRPEH 6 C3 B04L-30/M/24A1 (Material Number R901382345) is a high-response, direct-operated proportional directional valve with integrated digital on-board electronics (OBE) and electrical position feedback. Designed and manufactured by Bosch Rexroth, this valve belongs to the proven 4WRPEH series and serves as a precision control element for regulating both the direction and magnitude of hydraulic flow in proportion to an electrical input signal. The valve features a nominal size 6 (NG6 / CETOP 3) subplate interface and a 4-way, 3-position spool configuration with a closed-center (C3) design. Its integrated OBE electronics with a ±10 V or 4–20 mA command interface deliver exceptional dynamic response, minimal hysteresis, and outstanding repeatability, making it an ideal choice for closed-loop position, velocity, and force control in demanding industrial and mobile hydraulic systems.
