PosiDot Meter Mix Dispense Micro-Valve
The PD44 is specifically designed to repeatably dispense volumes from 0.005 cc's up to 5 cc's of two part Silicones, Epoxies, and Urethanes materials.
The PD44 Valve features balanced inlet/outlet spool assemblies that do not displace material while shifting from the reload to the dispense position. This allows pressure feeding of the “A” and “B” components up to 1200 psi during reloading while isolating the materials from the mixer inlet. Upon shifting to the dispense position, an accurate volume of “A” and “B” components is injected into the disposable mixer inlet by rod displacement metering technology. Shots from 0.005 to 5 cc’s and handle material ratios from 1:1 to 25:1.
