Product Description
4WRPEH6 Series Direct-Operated Proportional Servo Valve with OBE
Product Overview: The Rexroth 4WRPEH6 is a direct-operated proportional directional valve offering servo-level dynamic performance. Its primary advantage lies in the integration of OBE (On-Board Electronics) and an inductive spool position feedback system. Compared to standard proportional valves, the 4WRPEH6 provides significantly faster dynamic response and minimal linearity error, enabling precision position and pressure control even at high switching frequencies. This valve is the ideal choice for demanding closed-loop applications such as synchronized cylinder control, plastics processing machinery, and precision machine tools.
Featured model: 4WRPEH6CB24L-20/G24K0/A1M (Material No: 0811404355).
Key Technical Advantages:
Servo-Level Dynamics: High-efficiency proportional solenoids directly actuate the spool, providing an exceptional frequency response bandwidth for rapid and stable system movements.
Integrated OBE Electronics: The factory-integrated signal processing and power amplifier modules allow for “Plug-and-Play” operation while providing robust immunity to external electromagnetic interference.
High-Precision Feedback: An inductive displacement transducer monitors the spool position in real-time. This feedback to the OBE reduces hysteresis to < 0.1%, ensuring extreme linearity of the output flow.
Compact Direct-Operated Build: Fits the Size 6 (NG6) mounting interface, offering a compact design that saves valuable space in manifold integrations.
