Product Overview

The Rexroth M-3SED 6 CK13/350CG24N9K4/B15 (Material No. R900224515) is a direct-operated solenoid directional seat valve designed for leak-free load holding and precise flow direction control in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve features a poppet-type seat design that ensures zero internal leakage in the closed position, making it ideal for applications requiring reliable load holding or pressure isolation. The valve is actuated by a wet-pin DC solenoid with a nominal voltage of 24 VDC and includes a manual override for emergency operation. With a size 6 (NG6 / CETOP 3) interface, it delivers a maximum operating pressure of 350 bar and a nominal flow capacity of up to 60 L/min, providing robust performance in demanding hydraulic circuits.
