Product Overview
The Rexroth 15 KE05-1X (Material Number R900345372) is a direct-acting check valve designed for hydraulic flow control and modular manifold integration. As part of the Rexroth KE series, this valve permits free flow in one direction while blocking reverse flow with a zero-leak, spring-loaded poppet or ball seat design. The “KE05” size designation indicates a nominal NG6 (CETOP 3 / ISO 4401-03) interface, making it a compact, drop-in component for sandwich plate and manifold systems. The “-1X” suffix denotes the Rexroth series 10 to 19 design generation, ensuring backward compatibility with existing modular stacks. This valve is engineered for reliable leak-tight sealing in high-pressure industrial circuits, providing essential backflow protection for pumps, actuators, and directional control valve blocks.

Engineering Features & Advantages
- Precision Performance: Spring-loaded poppet/ball seat ensures fast, positive closure and zero leakage in the blocked direction, protecting sensitive downstream components from reverse flow surges.
- Modular Sandwich Design: NG6 interface allows direct stacking between directional control valves and subplates, reducing piping complexity and leak points in manifold assemblies.
- Industrial Reliability: Hardened steel internal components and robust housing are built for continuous operation under severe industrial conditions, including high-pressure and high-cycle applications.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth KE05-1X and R900345372 specifications, ensuring drop-in replacement without system modification.
- Low Pressure Drop: Optimized flow path minimizes pressure loss in the free-flow direction, improving overall system efficiency and reducing heat generation.
Typical Industrial Applications
This Rexroth check valve is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and construction & marine hydraulic systems. It is commonly used to prevent load dropping in lifting circuits, isolate pump lines during multi-actuator operation, and provide backflow protection
