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

Revision B /February 2022 Page 6 of 23
Nozzle Options
The FC100-CF valve is available with a variety of film coat nozzles. All nozzles have a
different orifice to allow for a maximum flow rate and a slit to create a fan shaped flow
pattern. The width of the fan pattern is determined by the distance from the valve nozzle
to the substrate. Different nozzles are easily interchangeable to the valve by removing the
nozzle cap (5).
Nozzle sizes are selected based on the viscosity of the coating fluid and desired coating
thickness. PVA’s application engineers can help you select the best nozzle for your valve.
Valves are supplied from the factory with one nozzle included.
Below is a chart showing the part numbers that are used to specify the nozzle that is
supplied with a valve and the available orifices, flow rates, and fan widths, for each
individual nozzle.
Nozzle Part Number

Safety
Due to material contents being under pressure eye protection is required for operators.
Refer to MSDS sheets on material being dispensed for other precautions.

FC100-CF Manual
Revision B /February 2022 Page 8 of 23
Setup
The FC100-CF requires a 2-position, 4-way air solenoid valve to actuate the air section.
The valve should be operated with clean, dry air between 60-100 psi. Two #10-32 threaded
air ports are located on the air section of the valve. The port located furthest from the
midsection of the valve is air to close the valve. The port located closest to the mid-section
of the valve is air to open the valve. Quick connect air fittings are typically supplied with
the FC100-CF to fit 5/32 in tubing.
Note: The valve should normally be in the closed position.
Fluid is supplied to the FC100-CF through the 1/8 in fnpt port located on the stainless steel
fluid section of the valve.

Operation
Refer to Figure 8: FC100-CF Cross Section for part reference numbers.
1. Plumb up the valve as outlined above in the Setup procedures.
2. Regulate the air pressure operating the valve between 60-100 psi.
3. Ensuring the valve is not aimed toward anyone, cycle the valve several times. When
the valve is cycling, the piston can be heard hitting the micrometer adjustment, and
the needle (2) can be seen going up and down in the center.
Note: If the valve is not cycling properly, refer to the Troubleshooting section.
4. When the fluid delivery system is connected to the valve, pressurize the material to
be dispensed.
5. Once again, cycle the valve open to purge. Fluid should begin to dispense from the
for tip nozzle of the valve, continue dispensing until all air is removed.
6. Check the fluid connection and the packing nut (17) for leaks.
Note: If the valve is leaking, refer to the Troubleshooting section.
7. Turn the micrometer adjustment head (6) until the desired flow rate is achieved.
Turning the adjustment clockwise toward zero will decrease the material flow rate
and counterclockwise will increase the material flow rate. If the micrometer
adjustment is turned all the way down to zero, it will stop fluid flow entirely.
8. Once the micrometer setting is determined, the collar (Figure 9, Part E) on the
micrometer head (6) can be turned clockwise to lock the adjustment.
Periodic Maintenance
Refer to Figure 7: FC100-CF Cross Section and Figure 8 for location of parts referenced in
the following procedures.
1. Lubricate the packing (16) on the FC100-CF valve every 200 hrs by placing a few
drops of mineral oil or other light oil inside the packing nut.
2. The packing nut (17) may require occasional tightening, as wear occurs in order to
prevent leaks through the packing.
Note: PVA offers a 2.5cc mineral oil lubrication kit; Part#: B62-0752
