Product Description

Rexroth Type 4WRZ25 Series Pilot-Operated Proportional Directional Valves

Product Overview: The 4WRZ25 Series is a high-performance, two-stage pilot-operated proportional directional valve engineered for high-power hydraulic systems. By utilizing a proportional pilot stage to modulate the main spool, this series enables stepless and precise regulation of massive flow rates. As the industry standard for Size 25 (NG25 / CETOP 08) footprints, it is essential for heavy-industrial applications requiring rapid response and high synchronization accuracy.

This category showcases premium configurations from both the 50 and 7X design sequences: the robust 4WRZ25W3-325-50/6A24NEK4/M and the cutting-edge 4WRZ25W6-325-7X/6EG24N9EK4/D3M. These valves are the premier choice for large-scale die-casting machines, steel mill automation, mining machinery, and high-output hydraulic power units.

Key Technical Advantages:

  • Superior High-Flow Regulation: The pilot-operated architecture allows for smooth proportional control of flow rates up to 600 L/min with minimal electrical input power.

  • Multi-Generational Design (50/7X): The latest 7X sequence incorporates advanced solenoid technology (EG24) and optimized fluid dynamics for lower hysteresis and enhanced dynamic stability.

  • Versatile Connectivity: Equipped with EK4 (Square plug) and D3M interfaces, ensuring seamless integration with modern PLCs and proportional amplifiers.

  • Industrial Durability: Rugged iron castings and M (NBR) seals ensure long-term stability under high pressure (315 Bar), significantly reducing maintenance overhead.
