Product Overview
The Rexroth M-3SEW 10 U1X/420MG24N9K4 (Material Number: R900055561) is a high-performance direct-operated solenoid directional seat valve designed for precise control of start, stop, and direction of hydraulic fluid flow. As part of the Rexroth M-3SEW series, this valve features a robust seat valve design (poppet type) that ensures zero leakage in the closed position, making it ideal for applications requiring secure load holding and leak-free operation. The “10” size designation indicates a nominal flow capacity optimized for industrial circuits, while the “U1X” series denotes the standard Rexroth modular design with a wet-pin AC/DC solenoid. This valve is engineered for demanding B2B industrial environments, offering high switching reliability and long service life in hydraulic power units, presses, and machine tools.

Engineering Features & Advantages
- Zero-Leakage Sealing: The seat valve (poppet) design provides bubble-tight shut-off, preventing internal leakage and ensuring secure load holding in critical clamping and pressing applications.
- High-Pressure Capability: Rated for continuous operation up to 420 bar, making it suitable for high-pressure industrial hydraulic systems where standard spool valves may fail.
- Direct Solenoid Actuation: Fast and reliable switching with a wet-pin DC solenoid, reducing response time and eliminating the need for pilot pressure in many circuits.
- Manual Override: Integrated manual override (N9K4 designation) allows for emergency operation and system diagnostics without electrical power.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction that resists contamination and wear.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification.
Typical Industrial Applications
This Rexroth solenoid directional seat valve is widely used in heavy industrial scenarios including: plastic injection molding machines for precise mold clamping and injection pressure control; metallurgical presses for high-pressure forming and holding operations; <
