Product Overview
The Rexroth 3DREPE 6 C-21-25EG24N9K31/F1M-00 (Material Number: R900958859) 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 system supply pressure to a command-dependent secondary pressure at port A, maintaining that pressure against variations in flow and load. Actuation is achieved via a proportional solenoid with central electrical connection, allowing the outlet pressure to be continuously modulated in proportion to the solenoid current. The valve is engineered for high-resolution pressure regulation, making it suitable for demanding applications where accurate force, torque, or pressure profiling is required.
