Product Overview
The Rexroth R901531818 is a high-performance solenoid-actuated directional spool valve engineered for precise control of start, stop, and direction of hydraulic fluid flow in industrial hydraulic systems. As part of the Rexroth directional spool valve family, this component utilizes a hardened, precision-ground spool and sleeve assembly housed within a robust cast iron body, ensuring minimal internal leakage and long service life. The valve is actuated by a wet-pin AC or DC solenoid, providing fast, reliable shifting with high switching force and excellent resistance to contamination. Designed for manifold mounting in accordance with ISO 4401 / DIN 24340 standards, the R901531818 serves as a critical control element in demanding circuits requiring dependable directional control, load holding, and actuator sequencing.
