PD44 Patented Meter, Mix & Dispense Valve

Brand: Graco, Inc
Request Information

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.
