3.3 Fluid connection
The valve must be connected to a power supply unit (tank, pump or other). A hose must be connected to the connector
in the lower part of the valve. If you work at pressures above 8 bar use fittings and pipes for high pressure .
3.4 Setting of the valve
The adjustment of the stroke of the plunger determines together with the pressure of
the material and the opening time of the amount of fluid dispensed.
> Micrometric version:
To adjust the stroke to act on the adjustment knob on the upper part of the valve.
Rotate clockwise to decrease the travel of the needle and consequently, the amount
is fluid. Turn clockwise coming all the way the valve will be fully closed, so it will
dispense fluid.
Rotate counterclockwise to increase the stroke of the plunger and therefore the
amount of fluid.
3.5 Setting of the material quantity
The adjustment of the quantity of material is determined by:
> The nozzle diameter (0.3 - 0.5 - 0.8 - 1.0 - 1.5)
> The pressure of the fluid
> Adjusting the stroke of the needle
Acting on these factors one can adjust the amount of desired material.
