Product Overview
The Rexroth 045930038620000 (also designated R930006131) is a high-performance solenoid-actuated directional cartridge valve engineered for precise control of hydraulic flow direction in demanding industrial circuits. As part of the Rexroth directional spool valve family, this cartridge-style valve utilizes a hardened, precision-ground spool and sleeve assembly that shifts in response to an integral solenoid pilot signal, directing pressurized fluid to the selected work port while venting the opposite port to tank. Its slip-in cartridge construction allows direct installation into a machined manifold cavity, eliminating external piping, reducing leakage paths, and enabling compact, high-density hydraulic power units. The valve is designed for continuous duty in systems requiring fast, repeatable directional control with minimal pressure drop and reliable long-term sealing.
