Product Overview
The Rexroth 3SED6CK14/350CG24N9K4 (Material No. R900055392) is a high-performance directional seat valve manufactured by Bosch Rexroth, engineered for precise hydraulic flow control in demanding industrial systems. This direct-operated, spring-return seat valve features a poppet-type sealing element that provides zero-leakage shut-off in the closed position, making it ideal for applications requiring reliable load holding and tight sealing integrity. The valve is actuated by a wet-pin DC solenoid (24V DC) with a nominal pressure rating of 350 bar, ensuring robust switching performance in high-pressure hydraulic circuits. As part of the Rexroth SED6 series, this valve is designed for direct mounting via a standard ISO 4401-03 (CETOP 3) interface, delivering exceptional response times and long service life in continuous industrial operation.
