Product Overview
The Rexroth 3DREPE 6 C-21/25EG24N9K31/A1M (Material Number R900955784) is a direct-operated, three-way proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. As a member of the Rexroth 3DREPE series, this valve reduces a primary system pressure to a lower, electrically modulated secondary pressure proportional to the input command signal. The integrated proportional solenoid converts current input into a proportional mechanical force acting against a control spool, enabling stepless pressure regulation with high resolution and excellent repeatability. This valve is engineered for demanding closed-loop and open-loop pressure control circuits where accurate, dynamic pressure modulation is essential for machine performance and process consistency.
