Product Overview
The Rexroth 3DREPE 6 C-21-25EG24N9K31/A1M-00 (Material No. R900958788) is a direct-operated, three-way proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. As part of the Rexroth 3DREPE series, this valve reduces a primary system pressure to a lower, electrically commanded secondary pressure at port A, while simultaneously limiting pressure rise at port B through its three-way spool design. The integrated proportional solenoid converts an analog electrical command signal into a proportional mechanical force acting on the control spool, enabling stepless pressure regulation independent of flow demand. This valve is engineered for demanding closed-loop and open-loop pressure control circuits where accurate, repeatable pressure modulation is essential.
