Product Overview
The Rexroth 3DREP 6 C-21=25EG24N9K4/M-00 (Material No. R900956101) 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 3DREP 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 valve is actuated by a proportional solenoid with central thread and detachable coil, converting an analog electrical command signal into a proportional hydraulic output pressure. This enables stepless pressure regulation, soft-start and pressure ramp functions, and closed-loop pressure control when combined with an external pressure transducer and Rexroth amplifier card. The 3DREP 6 C-21=25EG24N9K4/M-00 is a size 6 (NG6 / CETOP 3) valve with a nominal flow capacity of 25 L/min and is intended for subplate mounting in manifold or sandwich plate assemblies. Its robust construction, precise spool-to-bore fit, and high-resolution solenoid make it a preferred choice for demanding pressure-control circuits in injection molding, metallurgy, and general industrial automation.
