Liquid product can be dispensed by controlling head pressure in a closed pressure vessel. Whether it is a liquid, solder paste or flux dispensing application, stable and repeatable pressure control will provide the most consistent dispensing results.
In this example a QPV1 is being used to precisely control air (or inert gas) pressure in the vessel. This type of control eliminates dispensing changes because of weight experienced in a gravity fed system.
The QPV employs a true proportional inlet valve that allows for extreme resolution (up to ±0.005% of full scale calibration). Having great resolution allows the dispensed material to be very finely manipulated.
