Product Overview
The Rexroth 4WRTE16W6-200L-46/6EG24TK31/A1M (Material Number R901022813) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRTE series, engineered for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 16 (NG16) nominal bore, the valve utilizes a two-stage design in which a proportional pilot valve with integrated control electronics actuates the main spool via hydraulic pilot pressure. The “W6” spool designation provides a specific metering characteristic (progressive flow profile) suited to applications requiring fine low-command resolution and smooth velocity transitions. With a nominal flow rating of 200 L/min at a 10 bar (Δp) valve pressure differential, the 4WRTE16W6 delivers high flow capacity while maintaining excellent dynamic response and repeatability. The integrated 24 VDC solenoid with on-board amplifier (TK31 electronics) enables direct command interfacing with analog setpoint signals, making this valve a core control element in closed-loop position, velocity, and force control architectures for injection molding, metallurgical, and general industrial machinery.
