Fluid quantity adjustment
The adjustment of the dispensed fluid quantity (ex. glue) by the valve is determined by:
\)
The nozzle diameter: greater diameter → more fluid quantity
\)
The fluid pressure: greater pressure → more fluid quantity
\)
The needle travel adjustment: greater needle travel → more fluid quantity
Operating on this points it’s possible to adjust the dispensed fluid quantity.
To adjust the needle travel, operate on the
