Product Overview
The Rexroth 4WRTE 10 Q2-100P-42/6EG24EK31/A5M (Material Number: R900773306) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRTE series, designed for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a four-way, three-position (4/3) spool configuration with integrated position feedback, this valve delivers exceptional dynamic response and repeatability. The “Q2” designation indicates a high-response variant with optimized spool geometry for fast, accurate positioning, while the “100P” rating reflects a nominal flow capacity of 100 L/min at a 10 bar pressure drop per land. The valve is actuated by a single proportional solenoid with 24 VDC (EG24) supply and features an integrated amplifier (EK31) with position transducer feedback, ensuring closed-loop control of the main spool. With a size 10 (NG10) interface per ISO 4401, this valve is engineered for seamless integration into high-performance hydraulic circuits requiring precise velocity and position control of actuators.
