Product Overview
The Rexroth M-3SED10CK14/350CG24N9K4 (Material Number: R900086685) is a direct-operated solenoid directional seat valve engineered for precise control of hydraulic fluid flow direction in industrial systems. Manufactured by Bosch Rexroth, this valve belongs to the proven 3SED series, which is renowned for its leak-free sealing characteristics in the closed position. The valve operates on a seat-type working principle, utilizing a hardened steel ball or poppet that seats against a precision-machined valve seat to achieve zero-leakage isolation when de-energized or energized. With a size 10 (NG10) interface, this component serves as a critical control element in hydraulic circuits requiring reliable shut-off and directional switching, commonly functioning as a pilot valve or direct control valve in high-pressure industrial machinery.
