The Rexroth R900420674 DRE4K-31/18G24-10NK4M is a high-performance, pilot-operated proportional pressure reducing valve. Designed as a 3-way version for subplate mounting, it provides precise and continuous control of pressure in hydraulic systems. This valve effectively reduces and maintains a constant secondary pressure, independent of inlet pressure fluctuations. It features integrated electronics (OBE) for straightforward control via a 24V DC signal, making it ideal for sophisticated industrial applications such as in machine tools, presses, and automated manufacturing lines where accurate pressure regulation is critical for performance and safety.
