PD44 Patented Meter, Mix & Dispense Valve
Brand: Graco, IncThe 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.
