Product Overview
The Rexroth S6A3.0 directional spool valve (material number R900422884) is a direct-operated, solenoid-actuated directional control valve designed for precise switching and routing of hydraulic fluid in industrial power units. Part of the proven Rexroth S6 series, this valve uses a hardened, precision-ground steel spool that slides within a close-tolerance housing bore to connect or block flow paths between the pressure, tank, and actuator ports. With a nominal size of 6 (NG6 / CETOP 3 interface) and a nominal flow rating of 3.0 L/min, the S6A3.0 is engineered for low-flow control circuits where accurate, repeatable directional control is required. Its compact subplate mounting design allows fast integration into manifold blocks and standard connection plates, making it a reliable building block for machine tools, test stands, and other industrial hydraulic systems requiring dependable directional spool valve performance.
