Theory of Operation
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 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
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.
Wetted parts on the FC100-CF include:
- 303, 304 stainless steel
- Teflon
- Kalrez
