Product Overview
The Rexroth 20 KE05-1X (Material No. R900340979) is a direct-operated directional spool valve from the proven Rexroth KE series, engineered for precise control of start, stop, and direction of hydraulic fluid flow in industrial power units. As a solenoid-actuated directional control valve, it utilizes a hardened, precision-ground spool within a high-tolerance valve housing to route pressurized oil between ports with minimal internal leakage. The 20 KE05-1X is a size 5 (NG5 / CETOP 3) valve designed for manifold or subplate mounting, delivering reliable switching performance in demanding hydraulic circuits where accurate directional control and long service life are essential.
