Product Description
Rexroth Type 4WRZ25 Series Pilot-Operated Proportional Directional Valves
Product Overview: The 4WRZ25 Series is a high-capacity, pilot-operated proportional directional valve designed for large-scale hydraulic systems. Utilizing a two-stage architecture—a proportional pilot stage and a main stage controlled by pilot pressure—this series offers precision control over flow magnitude and direction. As the industry standard for Size 25 (NG25) footprints, it delivers exceptional dynamic response and handles massive flow rates, making it ideal for synchronization and speed regulation in heavy industries.
This category highlights essential high-performance configurations: the 4WRZ25W2-325-5X/6A24NTK4/D3M (325 L/min rated flow) and the classic E-spool 4WRZ25E220-5X/6A24N9K4/M. These valves are the premier choice for large injection molding machines, steel mill automation, heavy-duty forging presses, and marine hydraulic systems.
Key Technical Advantages:
Superior Flow Regulation: The pilot-operated design enables stepless proportional control of flow rates up to 600 L/min with minimal electrical input power.
High-Response Pilot Stage: Optimized under the 5X design sequence, featuring high-performance proportional solenoids that ensure minimal hysteresis and superior repeatability under fluctuating loads.
Versatile Electrical Connectivity: Supports multiple wiring formats including K4 (large square plug) and D3M interfaces, adapting to diverse industrial control cabinet requirements.
Comprehensive Spool Functions: Available in E-spool (closed center) and W2 configurations (special proportional characteristics) to meet various logic requirements from pressure holding to differential control.
