Product Description
Rexroth 4WRPH Series High-Response Servo-Proportional Valves
Product Overview: The Rexroth 4WRPH series (including 4WRPH6 and 4WRPH10) sets the standard for precision in direct-operated proportional directional valves. Designed for industrial applications requiring extreme dynamic response and high-accuracy closed-loop control, these valves feature Integrated Electronics (OBE). The 4WRPH series achieves servo-level performance, making it the ideal choice for injection molding machines, die-casting equipment, test stands, and complex machine tool controls. The precision-engineered spool combined with LVDT feedback ensures minimal hysteresis and superior repeatability throughout the entire stroke.
Featured models: 4WRPH6C4B40L-20/G24Z4/M, 0811404039, 4WRPH10C4B100L-2X, and 4WRPH6C4B12L-2X/G24Z4/M.
Key Technical Advantages:
Servo-Grade Dynamics: Exceptional frequency response bandwidth allows for flawless tracking of fast-changing command signals for precise position and pressure control.
Integrated OBE (On-Board Electronics): Digital control electronics are integrated directly onto the valve, simplifying external wiring and enhancing EMI resistance.
Closed-Loop Feedback: Utilizes high-precision LVDT displacement sensors for real-time spool position monitoring, reducing hysteresis to near-zero levels.
Rugged Reliability: Industrial-strength design with excellent vibration resistance and thermal stability, rated at IP65 protection.
Versatile Flow Options: Available in various spool capacities from 12L/min to 100L/min (at specific pressure drops) to match different actuator requirements.
