Rexroth 4WRL16 Series Two-Stage High-Performance Proportional Servo Valves

Product Overview:

The Rexroth 4WRL16 Series is a two-stage high-performance proportional directional valve engineered for hydraulic systems requiring high flow rates and exceptional dynamic response. As a standard Size 16 (NG16) valve, it utilizes a precision pilot stage to actuate the main spool, coupled with an integrated LVDT (Linear Variable Differential Transformer) for real-time position feedback. The 200M rating denotes a superior flow capacity of 200 L/min at rated pressure drop, making it the premier choice for presses, metallurgical equipment, and heavy-duty machine tool control systems.

Featured models on this page include the classic Series 3X 4WRL16V-200M-30 and the latest optimized Series 4X 4WRL16V-200M-4X.

Key Technical Advantages:

• Two-Stage Control Architecture: Combines a high-response pilot stage with a high-flow main stage to precisely regulate massive hydraulic power under high-pressure conditions.

• Precision Electrical Feedback: The integrated high-resolution displacement sensor ensures closed-loop control of the main spool, significantly reducing hysteresis and enhancing repetitive accuracy.

• Ultra-Fast Dynamic Response: Optimized internal geometry and pilot characteristics provide servo-grade frequency response bandwidth.

• Versatile Configuration: Supports various pilot oil supply and return options (internal/external), making it compatible with complex manifold block designs.
