Product Overview

The Rexroth M-3SED 6 CK14/350CG24N9K4/B05 (Material No. R900224556) is a direct-operated solenoid directional seat valve designed for leak-free load holding and precise flow direction control in industrial hydraulic systems. As a member of the Rexroth 3SED series, 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 AC/DC solenoid (24V DC, high-performance design) and is available with a manual override for emergency operation. With a nominal size of NG6 (CETOP 3 / ISO 4401-03), it is engineered for compact manifold mounting and delivers dependable switching performance in demanding hydraulic circuits.
