The Graco PD44 Patented Meter, Mix and Dispense Valve
The Graco PD44 is specifically designed for micro dispensing two-component materials. It dispenses 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. What’s more, there are no material hoses between the rod pump outlets and mixer inlet which eliminates potential ratio or shot size problems (phasing) due to hose expansion and contraction.
