Product Overview
The Rexroth 3DREP6A-21/45EG24N9K4/M (Material Number R900962045) is a directly operated, three-way proportional pressure reducing valve from the proven DREP series. It is engineered to continuously convert an electrical input signal into a proportional hydraulic output pressure, enabling stepless, infinitely variable pressure control within industrial hydraulic circuits. The valve operates on a three-way pressure reducing principle, simultaneously regulating the consumer (A) port pressure while providing a return path to tank (T), which allows it to control pressure even under varying load and flow conditions. With a size 6 (NG6 / CETOP 3) subplate mounting interface and a nominal flow capability of 45 L/min, this valve serves as a precise electro-hydraulic interface for pressure regulation, load simulation, and force-controlled actuation in demanding machinery. The integrated proportional solenoid (24 V DC, N9 coil with component plug per DIN EN 175301-803) delivers high actuating force and excellent repeatability, making the 3DREP6A-21/45EG24N9K4/M a reliable choice for closed-loop pressure control architectures.
