The perfect valve for every application

Metering valves and dispensing valves from DOPAG demonstrate all the qualities that are essential for optimum results in metering: high precision, excellent reproducibility and high quality standards. The DOPAG range includes various valve types, all of which are based on one of two dispensing principles. The needle and chamber metering valves work on the volumetric principle (dot application). Here, each cycle means that the contents of the valve chamber are completely emptied upon a trigger signal. This has the advantage of high repetition accuracy and flexibility thanks to the possibility of volume adjustment. On the other hand, dispensing, spray and shot valves work on a different principle, where the discharged quantity is defined by material pressure and valve needle opening time. This allows for application of small quantities from a distance, as well as continuous applications of any material amount.
