Product Description

Rexroth Type 4WRREH6 Series Pilot-Operated Proportional Directional Valves with Integrated Electronics (OBE)

Product Overview: The 4WRREH6 Series is a high-performance, pilot-operated proportional directional control valve featuring the industry-standard Size 6 (NG6 / CETOP 03) footprint. This series integrates high-end On-Board Electronics (OBE) for closed-loop spool position control, delivering exceptional dynamic response, minimal hysteresis, and superior linearity in complex hydraulic systems.

This category highlights the primary part number 0811404720 (4WRREH6VB12L-10/G24K0/B5M) and the high-flow variant 4WRREH6VB40L-1DG24K0B5M. These valves are essential for high-performance molding machines, die-casting equipment, flight simulators, and precision metallurgical control systems.

Key Technical Advantages:

  • Integrated Electronics (OBE): Features an onboard proportional amplifier and position transducer for real-time spool monitoring and precise correction, simplifying external wiring and enhancing EMI resistance.

  • Pilot-Operated Architecture: The pilot stage ensures smooth main spool actuation even under peak system pressures, providing high frequency response characteristics.

  • Superior Dynamics: Specifically engineered for closed-loop control systems, capable of handling sophisticated pressure and flow composite control commands.

  • B5M Industrial Interface: Utilizes standardized electrical connection protocols, ensuring seamless integration with mainstream PLCs and control systems.
