Rexroth 3DREP 6 Series Proportional 3-Way Pressure Reducing Valves

Product Overview:

The Rexroth 3DREP 6 series is a direct-operated proportional 3-way pressure reducing valve engineered for precise, stepless pressure regulation within hydraulic systems. By utilizing proportional solenoids to actuate the spool directly, it converts electrical input signals into proportional output pressure. Commonly used as a pilot valve for larger directional valves or for fine pressure control of actuators, the 3DREP 6 series—including 3DREP6A (single solenoid), 3DREP6B, and 3DREP6C (double solenoid)—is renowned for its compact design, rapid response, and high repeatability.

Featured models: 3DREP6C-14/25A24NZ4M, 3DREP6A-14/45A24NK4M, and 3DREP6B-2X/25EG24N9K4/M.

Key Technical Advantages:

• Direct Proportional Control: Spool positioning is controlled directly by the proportional solenoids, requiring no pilot oil and offering quick activation.

• 3-Way Functionality: Capable of pressure reduction from port P to A/B and relief from A/B to T, maintaining stable secondary pressure.

• Versatile Configurations (A/B/C): Supports symmetrical or asymmetrical pressure control to match various system logic requirements.

• Robust 1X/2X Design Series: Features optimized coil sealing and internal galleries for long-term durability and low hysteresis during high-cycle operation.

• Flexible Electrical Connectivity: Offers multiple connector types like Z4 or K4, compatible with standard industrial 24V DC power supplies.
