Product Overview
The Rexroth 25 KE05-1X (Material Number: R900344778) is a high-performance directional spool valve from the proven Rexroth KE series, engineered for precise control of hydraulic fluid flow direction, start, stop, and pressure regulation in demanding industrial circuits. This direct-operated, solenoid-actuated directional control valve features a robust spool-in-housing design that ensures rapid response, minimal internal leakage, and consistent switching performance across the full operating pressure range. With a nominal size of 25 (NG25 / CETOP 8 interface), the KE05-1X is designed for high-flow applications where reliable directional control and long service life are critical. The valve is widely deployed as a central control element in complex hydraulic power units, manifolds, and integrated systems requiring dependable, repeatable spool positioning.
