Product Overview
The Rexroth 4WRPH 6 C4 B24L-20/G24Z4/M (Material Number: 0811404038) is a high-response, direct-operated proportional directional valve from the renowned Rexroth 4WRPH series. Engineered for precise electro-hydraulic control, this valve features a 4-way, 3-position spool configuration with a nominal size of NG6 (CETOP 3 / ISO 4401-03). It utilizes a proportional solenoid on one end (designated by “Z4” for the electrical connection) to infinitely vary spool position, thereby controlling both flow direction and magnitude in proportion to the electrical input signal. The “B24L” spool type indicates a specific flow characteristic (linear with overlap), while the “20” designates the component series. This valve is a critical component in closed-loop control systems, offering exceptional dynamic response, minimal hysteresis, and high repeatability for demanding industrial motion control applications.
