Product Overview
The Rexroth M-3SED6CK14/350CG205N9K4 (Material Number: R900223863) is a direct-operated solenoid directional seat valve designed for reliable shut-off, release, and directional control of hydraulic fluid flow in industrial hydraulic systems. As a member of the Rexroth SED6 series, this valve features a poppet-type seat design that ensures zero-leakage sealing in the closed position, making it ideal for applications requiring tight holding and load-holding capability. The valve is actuated by a wet-pin AC or DC solenoid and returns to its normal position via a mechanical spring when de-energized. With a nominal size of NG6 (CETOP 3 / ISO 4401-03), it integrates seamlessly into standardized manifold and subplate mounting configurations. The “350” designation indicates a maximum operating pressure of 350 bar, while the “CG205” coil code and “N9K4” electrical connection identify the specific solenoid and connector configuration. This valve is engineered for high-cycle industrial duty, offering fast response, minimal pressure drop, and long service life in demanding hydraulic circuits.
