PD44
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.
- 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
