Rexroth 3DREPE6C Proportional Valve | R900958859 | 3DREPE6C-21/25 | Integrated OBE | DC 24V

Rexroth 3DREPE6C Series Proportional Valve with Integrated OBE

Product Overview:

The 3DREPE6C series represents the pinnacle of direct-operated 3-way proportional pressure reducing valves from Rexroth. The standout feature is the Integrated Electronics (OBE), which processes command signals directly on-board, eliminating the need for external amplifiers. This design significantly simplifies electrical wiring and achieves ultra-low hysteresis and high repeatability through internal closed-loop control. Whether for the 3DREPE6C-2X or -21 design series, these valves are the ideal choice for pressure control in injection molding, machine tool HPU, and precision actuators.

Featured models include: 3DREPE6C-2X=25EG24K31/F1M=00, 3DREPE6C-21=25EG24N9K31/F1M, and the official Part Number R900958859.

Key Technical Advantages:

• Integrated OBE Control: Built-in K31 interface electronics accept $0-10V$ or $4-20mA$ commands. This “plug-and-play” solution boosts noise immunity and system reliability.

• Precision Pressure Regulation: The 25 bar regulation range, paired with high-sensitivity proportional solenoids, ensures smooth transitions for even minute pressure changes.

• Ultra-Fast Dynamic Response: The direct-acting architecture eliminates pilot-stage lag, enabling pressure setpoint transitions within milliseconds.

• Industrial Ruggedness: Featuring F1M seal specifications and wet-pin EG24 solenoids, ensuring superior heat dissipation and chemical compatibility.
