To adjust the needle travel, operate on the
micrometric adjustment handle placed on the top
of the valve. This handle allows to adjust with a fine
control the dots or lines size that are dispensed.
A . Turn counter-clockwise to increase the needle
travel therefore the dispensed fluid quantity.
B . Turn clockwise to decrease the needle travel
therefore the dispensed fluid quantity. At the
end of the needle travel, the valve is completely
closed, therefore it doesn’t dispense any fluid.
Be careful not to unscrew too much the
adjustment, because above a certain limit
the magnet inside the valve will go out
from its working range, obstructing the
correct valve operating..
Don’t tighten with excessive force the
needle adjustment handle to avoid
damage to the nozzle and needle.
