Product Overview
The Rexroth R901170939 is a high-performance solenoid-actuated directional spool valve engineered for precise control of hydraulic fluid flow direction, start, stop, and pressure regulation within complex industrial hydraulic circuits. Manufactured by Bosch Rexroth, a global benchmark in drive and control technology, this valve belongs to the renowned 4WE series of directional spool valves. It utilizes a robust wet-pin AC or DC solenoid to shift a hardened, precision-ground steel spool within a high-tensile cast iron housing. This design ensures rapid, reliable response times and leak-free operation, making it an essential component for controlling actuators, cylinders, and motors in demanding B2B applications requiring high cycle rates and dependable directional control.
