Graco PR-Xv Advanced Variable Ratio Industrial Dispensing System

About the Graco PR-Xv Posi-Ratio®  Variable Ratio Two-Part Meter Mix System

The Graco PR-Xv meter system is engineered for highly abrasive two-component materials, with a flexible ratio range of 1:1 to 5:1 or 2:1 to 10:1. This makes it the ideal choice for bonding, gasketing, metering, potting, sealing, and thermal management applications. Its Posi-Ratio® (PR) technology delivers precision mixing, metering, and dispensing, while its high-wear-resistant construction withstands even the toughest thermal interface materials (TIMs), epoxies, and silicones. A patented first-in-first-out (FIFO) fluid path eliminates dead zones, preventing material buildup and ensuring accurate shot repeatability within 1%.

Graco PR-Xv Features and Benefits

• Extreme Ratio Flexibility: Adjust dispense ratios between 1:1 to 5:1 or 2:1 to 10:1.
  
• Superior Abrasion Resistance: Withstands TIMs, filled adhesives, and high-viscosity materials.
  
• FIFO (First-in-first-out) Fluid Path: Prevents material accumulation and clogging, reducing downtime.
  
• Recirculation Capability: Prevents material precipitation, ensuring smooth operation.
  
• Precision Servo Motors: Delivers consistent, repeatable dispensing.
  
• Twin Control (TC) Valve: Independently regulates A and B outlets for greater control.
  
• Integrated Pressure Monitoring: Built-in transducers provide real-time pressure feedback.
  
• Base Purge Function: Minimizes mixer consumption and reduces material waste.
  
• High Wear Option: Available for extended service life when handling fillers and other highly abrasive materials.
