Product Description
Rexroth Type 4WRZ & 4WRZE25 Series Pilot-Operated Proportional Directional Valves
Product Overview: The 4WRZ and 4WRZE25 Series are high-performance, two-stage pilot-operated proportional directional valves engineered for the precision control of massive flow in sophisticated hydraulic systems. As the industry benchmark for Size 25 (NG25 / CETOP 08) footprints, this series delivers exceptional dynamic response for flow rates up to 600 L/min. The 4WRZE variant features integrated On-Board Electronics (OBE) for seamless “plug-and-play” installation, while the 4WRZ offers superior flexibility for external control architectures.
This category focuses on premium configurations from the latest 7X design sequence: the high-flow 4WRZ25W8-325-7X/6EG24N9ETK4/M (Part No: R900719985) and the digital-ready 4WRZE25E1-220-7X/6EG24N9EK31/F1D3M. 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 ensures stability under high-pressure conditions (315 Bar) while allowing stepless, linear adjustment of actuator speed and direction.
Integrated On-Board Electronics (OBE/4WRZE): Factory-calibrated control circuitry mounted directly on the valve simplifies wiring and enhances electromagnetic compatibility (EMC).
Advanced 7X Design Sequence: Optimized internal fluid dynamics significantly reduce pressure drop and improve switching smoothness under high-inertia loads.
Versatile Signal Compatibility (D3M): Supports both analog and digital communication protocols. Combined with TK4 (Square plug) or EK31 (7-pin) interfaces, it perfectly matches the requirements of modern Industry 4.0 closed-loop systems.
