Product Overview
The Rexroth R901155051 is a high-performance solenoid-actuated directional spool valve engineered for precise control of hydraulic fluid flow direction, start, stop, and pressure regulation in industrial hydraulic systems. Manufactured by Bosch Rexroth, a global leader in drive and control technology, this valve belongs to the renowned 4WE series of directional spool valves. The R901155051 utilizes a robust wet-pin AC or DC solenoid actuator that shifts a hardened, precision-ground steel spool within a high-tensile cast iron or aluminum housing. This direct-acting design ensures rapid response times, minimal pressure drop, and exceptional leakage integrity. As a critical control element, it directs pressurized flow to specific actuator ports (A and B) while returning fluid from the opposite port to the tank (T), enabling forward, reverse, and neutral functions in complex hydraulic circuits. Its modular design allows for seamless integration into ISO 4401 standard mounting surfaces, making it a direct fit for a wide range of industrial machinery requiring reliable, repetitive directional control.
