Product Overview
The Rexroth R901488887 / R901050010 is a high-performance solenoid-operated directional spool valve engineered for precise control of start, stop, and direction of hydraulic fluid flow in industrial hydraulic systems. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this valve belongs to the renowned directional spool valve family, designed with a robust housing, hardened spool, and high-force wet-pin AC or DC solenoids. The valve operates on the principle of shifting a precision-ground spool within a machined bore via electromagnetic actuation, thereby directing pressurized flow to the selected work port while returning the opposite port to tank. Its direct-acting or pilot-operated configuration ensures fast response, minimal pressure drop, and reliable switching even under high system pressures. The R901488887 and R901050010 designations represent specific ordering codes for solenoid directional valves within the Rexroth portfolio, typically featuring a 4-way, 3-position (4/3) or 4-way, 2-position (4/2) spool configuration with spring return or detent options. This valve is a critical control element in demanding hydraulic circuits requiring precise directional control, load holding, and safe actuator positioning.
