Rexroth 4WRA & 4WRAP Series Proportional Directional Valves

Product Overview:

The Rexroth 4WRA and 4WRAP Series are essential components for achieving automated control in industrial hydraulic systems. The 4WRA Series is a direct-operated proportional directional valve, ideal for open-loop proportional control of flow and direction. The 4WRAP Series is the high-performance variant, specifically engineered for closed-loop or advanced open-loop systems requiring superior dynamic response and control precision. Driven by proportional solenoids, these valves provide stepless regulation of actuator speed and position based on input current, widely used in machine tools, woodworking machinery, and general industrial automation.

Featured models on this page include the high-performance 4WRAP6W7-02/07 and the standard proportional 4WRA10E60.

Key Technical Advantages:

• Precise Proportional Regulation: Optimized current-to-force solenoid characteristics ensure smooth, linear flow adjustment, effectively reducing hydraulic shock within the system.

• High Response & Reliability: The 4WRAP series features enhanced spool dynamics, maintaining excellent stability during frequent switching and high-speed cycles.

• Flexible Spool Configurations: Available in multiple spool functions, including E-type (closed center) and W-type (pressure relief center), to fit various hydraulic circuit logic.

• Ease of Integration: Designed with standard ISO 4401 mounting patterns for seamless integration into existing valve manifolds, compatible with Rexroth VT series proportional amplifiers.
