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 (
) 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 (
) for leaks.
Note: If the valve is leaking, refer to the Troubleshooting section.
7.
Turn the micrometer adjustment head (
) 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 (
) 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 (
) 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 (
) 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
