Product Overview
The Rexroth R901272641 is a high-performance solenoid-actuated directional spool valve engineered for precise control of hydraulic fluid flow direction, start, stop, and pressure regulation in demanding industrial circuits. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this valve operates on the proven directional spool principle, utilizing a hardened, precision-ground steel spool within a high-tolerance housing bore. Energizing the integrated wet-pin AC or DC solenoid shifts the spool axially against the centering spring, thereby opening or closing specific flow paths between the pressure (P), tank (T), and work ports (A and B). This model serves as a critical control element in hydraulic power units, manifolds, and centralized lubrication systems, delivering reliable switching performance and leak-tight sealing for continuous industrial duty cycles.
