Product Overview
The REXROTH M-4 SED 6 D13/350 C G125 N9K4 is a high-performance solenoid-actuated directional seat valve engineered by Bosch Rexroth for precise control of hydraulic fluid flow direction in industrial power units. Operating on the proven ball/seat sealing principle, this valve provides zero-leakage shut-off in the closed position, making it ideal for applications requiring positive load holding and leak-free isolation. The “M-4” designation indicates a manifold mounting pattern with a 4-way function, while the “SED 6” series denotes a size 6 (NG6 / CETOP 3) direct-operated seat valve. With a rated pressure of 350 bar (designated by “D13/350”), this valve delivers exceptional pressure capability for high-demand hydraulic circuits. The “C G125” code specifies the electrical solenoid configuration with a nominal voltage of 125 V DC, and the “N9K4” suffix identifies the specific spool/seat variant and manual override option. This valve is a direct-fit, drop-in replacement for OEM Rexroth installations, ensuring seamless integration into existing hydraulic systems without modification.
