The micro valve is actuated electromagnetically
HARD-SEALING VALVE STRUCTURE WITH SAPPHIRE AND RUBY
The short opening travel and the correct actuation allow the micro valve to be switched 4000 times per second long-term. The finely ground and polished optimal inner forms of the valve nozzle and valve seat provide the best possible flow properties before emergence. This results in an exactly dispensing jet for contactless dispensing and optimal drop formation.
Additional guide elements in and around the hard material components and the already mentioned advantages, if properly applied, make for a long micro valve life-time. By using these high-quality materials, high chemical and mechanical resistance and compatibility values are also achieved.
