Product Overview
The Rexroth M-3SED 6 (Material No. R901117458) is a direct-operated solenoid directional seat valve designed for leak-free shut-off and directional control of hydraulic fluid flow in industrial hydraulic systems. As a poppet-type seat valve, it operates on a positive sealing principle where a spring-loaded or solenoid-actuated poppet seats against a machined valve seat to isolate or connect ports. This design eliminates internal leakage in the closed position, making it ideal for clamping, holding, and load-locking circuits. The M-3SED 6 is a 3-way directional seat valve with a nominal size of NG6 (CETOP 3 / ISO 4401-03), available in AC or DC solenoid configurations. It is engineered for high switching reliability, fast response, and long service life in demanding industrial environments.
