Product Overview
The Rexroth M-3SEW6U38/630MG24N9K4/P (Material Number R900030919) is a direct-operated solenoid directional seat valve designed for leak-free load holding and precise flow direction control in high-pressure industrial hydraulic systems. As a member of the Rexroth SEW6 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 without drift. The “U38” spool/seat configuration provides a defined flow path with a specific cracking pressure characteristic, while the “630” pressure rating indicates a nominal operating pressure of up to 630 bar, suitable for demanding high-pressure circuits. The integrated MG24N9K4 solenoid is a 24 V DC wet-pin solenoid with a nominal power of approximately 30 W, featuring an ISO 4400 / DIN 43650 connector interface for straightforward electrical integration. This valve is engineered for use in hydraulic power units, clamping circuits, and safety-related control functions where dependable sealing and rapid response are critical.
