Graco MD2 Elite Two-Component Dispense Valve

Graco MD2 Elite Dispense Valve Overview

Graco's MD2 Elite Dispense Valve is engineered for precision two-component mixing and dispensing, offering exceptional durability and performance in demanding applications. Designed with wear-resistant seals and surfaces, the Elite version withstands abrasive materials such as thermal interface materials (TIMs), silicones, urethanes, and epoxies, lasting at least 10 times longer than standard dispense valves. Available in 1:1 and 10:1 ratios, this high-pressure valve features hard seats, non-adjustable snuff-back, and an adjustable stroke option for maximum control. The modular design streamlines maintenance, ensuring minimal downtime and easy serviceability without special tools.

For standard dispensing applications, consider the Graco MD2 Standard Dispense Valve for a cost-effective solution with multiple seat styles and snuff-back configurations.

MD2 Elite Dispense Valve Options

• Ratio (1:1 or 10:1): Available in both ratios for varied material mixing needs.
• Hard Seat Construction: All Elite models feature hard seats for maximum durability, designed to handle abrasive materials like silicones, urethanes, and epoxies.
• Snuff-Back Type (Non-Adjustable or Adjustable Stroke): Non-adjustable snuff-back provides reliable, maintenance-free shut-off, while the adjustable stroke option allows for precise control over dispense volume and cut-off performance.
