System Description
The FC100-CF is a front closing stainless steel film coat dispense valve designed to apply
fluids in a non-atomized method to deliver transfer efficiency greater than 99%. This valve
is typically used for low viscosity coatings.
The FC100-CF has a divorced design comprising of two major sections. These include:
1.
Air section (red anodized portion)
2.
Fluid section (stainless steel portion)
The air section is an aluminum body with a simple piston/cylinder combination used to
open and close the valve. A micrometer adjustment, Figure 9: Micrometer Adjustment
Breakdown, in the upper air body controls how far the piston and needle assembly can
retract thus regulating the rate of fluid flow. The micrometer will display a distance that the
piston and needle will travel.
The fluid section is a stainless steel body, which includes a needle and seat combination to
control fluid flow. Fluid dispenses as the needle retracts out of the seat, then stops as the
needle moves back into the seat. The micrometer adjustment regulates the distance that
the needle can retract out of the seat, thus controlling the orifice size and the rate of fluid
flow. A film tip nozzle at the end of the valve will fan the liquid outward without the need
for atomizing air to apply thin ribbon coating patterns. Fluids typically include solvent
based or low viscosity conformal coatings.
