Patented Meter, Mix and Dispense Valve

For micro dispensing two-component materials

The Graco PD44 is specifically designed to dispense small amounts of water thin to paste viscosity materials from 0.005 cc’s to 5 cc’s. The metering rods are matched with machined seals for improved seal life.

Features :

  • Specifically designed to accurately dispense shots of two-component epoxies, urethanes, silicone and most reactive resin systems
  • Improved low viscosity spool design
  • Rod positive displacement metering
  • Precise mix ratio and shot repeatability
  • Eliminates cleaning and potential hardening of materials in the valve
