Positive displacement valves are available as either servo driven auger valves or peristaltic dispensing pumps. An auger valve is a servo motor driven valve suitable for dispensing high viscosity pastes. A peristaltic dispensing pump is a volumetric valve with an adjustable chamber for accurate deposits.
The PDV1000 auger valve has been engineered to dispense small amounts of solder paste using positive displacement. The auger valve (commonly called a screw valve) is a servo driven system controlled by the PDC2000 controller for rotation speed, fluid pressure and reverse drive affecting snuff-back. The PDV1000 can also be used to dispense higher viscosity materials greater than 35,000cps.
The PDV-1000 series of precision auger valves is suitable for dispensing medium to high viscosity pastes, epoxies, solder pastes and other filled materials. Capable of dispensing a minimum shot size of 0.020" (0.508mm), the PDV-1000 uses an Archimedes auger servo-motor driven-screw for positive displacement. Select the syringe barrel size for the system
