Product Overview
The Rexroth R900771391 is a high-performance solenoid-actuated directional spool valve from the renowned 4WE series, engineered by Bosch Rexroth for precise control of hydraulic fluid flow direction in industrial systems. This direct-operated directional spool valve utilizes a robust solenoid actuator to shift a precision-machined spool within a hardened valve body, enabling reliable switching, holding, and directional control of hydraulic actuators such as cylinders and motors. Designed for demanding B2B hydraulic circuits, the R900771391 delivers fast response times, minimal pressure drop, and leak-tight sealing, making it a critical control component in manifold blocks and centralized hydraulic power units.
