Rexroth R900052621 M-3SED 6 UK13/350CG24N9K4
The Rexroth M-3SED 6 UK13/350CG24N9K4 is a direct-operated directional seat valve with solenoid actuation, designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. As a 3-way, 2-position valve, it features a robust design with a hardened valve seat and ball as the closing element, ensuring reliable operation and tight, leak-free shut-off. This valve is suitable for applications requiring fast switching times and dependable performance. The ‘UK13’ designation refers to its specific spool configuration and porting, while ‘350CG24N9K4’ indicates its maximum operating pressure (350 bar), a 24V DC solenoid, and a standard DIN electrical connector.
