What to do if the PVA FCS300 valve does not spray anything?
- RRebecca CowanAug 14, 2025
If your PVA Control Unit's valve isn't spraying anything, first, check if the fluid pressure is too low and increase it if necessary. Also, the material might have cured in the fluid section; if so, disassemble and clean the valve. Finally, ensure the micrometer adjustment bolt isn't set too close to zero by turning it counterclockwise.
