Product Overview
The Rexroth 4WRREH6VB8L-11/G24K0/B5M (Material Number: 0811404723) is a high-response, direct-operated proportional directional valve from the renowned Rexroth WRREH series. Engineered for precise electro-hydraulic control, this valve features a 4-way, 3-position spool configuration with a nominal size of NG6 (CETOP 3 / ISO 4401-03). It operates on a 24V DC proportional solenoid with integrated position feedback, enabling exceptional dynamic response and repeatable flow metering. The valve is specifically designed to manage both direction and magnitude of flow in proportion to an electrical input signal, making it a critical component in closed-loop industrial control systems requiring high accuracy and fast cycle times.
