Product Overview
The Rexroth R930081345 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 leader 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 steel spool within a precision-machined housing, directing flow from the pressure port to the designated actuator ports (A and B) and returning fluid to the tank port. Designed for direct pipe connection or manifold mounting, this valve serves as a critical control element in systems requiring high cycle rates, leak-free operation, and reliable switching performance under demanding industrial conditions.
