Product Overview
The Rexroth R900340979 is a high-performance directional cartridge valve from the proven KE05-1X series, engineered by Bosch Rexroth to deliver precise flow direction control within compact manifold and cartridge block assemblies. Operating on a direct-acting spool principle, this 2-way directional cartridge valve responds to pilot pressure signals to open, close, or redirect hydraulic flow with minimal pressure drop and fast switching response. Its slip-in cartridge design allows clean integration into custom manifold blocks, reducing external piping, minimizing leakage paths, and enabling high-density hydraulic circuit layouts in demanding industrial power units.

Engineering Features & Advantages
- Precision Spool Metering: Hardened, precision-ground spool and sleeve pairing delivers accurate flow direction control with minimal internal leakage and consistent response across the operating pressure range.
- Compact Cartridge Architecture: The slip-in KE05-1X design eliminates external pipework, reduces potential leak points, and enables high-density manifold integration for space-constrained hydraulic power units.
- Fast Switching Response: Direct pilot actuation provides rapid opening and closing characteristics, supporting precise sequencing in multi-actuator circuits.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust materials and surface treatments resistant to contamination and wear.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in interchangeability without manifold modification.
Typical Industrial Applications
The Rexroth R900340979 / 20 KE05-1X directional cartridge valve is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and construction and marine hydraulic systems where compact, reliable directional control is essential. It is equally suited to custom manifold blocks in general industrial power units requiring precise pilot-operated flow switching.
