What to do if the PVA FCS300 valve does not spray anything?
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.
Why are there air bubbles in the fluid of my PVA FCS300 Control Unit?
If you notice air bubbles in the fluid of your PVA Control Unit, it might be due to a few reasons. First, the valve may not be properly purged; try flipping it upside down and cycling it until the air bubbles are removed. Second, there might be an issue with the fluid delivery system, which would need diagnosing and repair. Lastly, the atomizing air pressure might be set too high, so try reducing it.
How to fix a PVA FCS300 Control Unit valve that does not cycle?
If the PVA Control Unit valve does not cycle, there could be several reasons. The air pressure to the air section might be too low; increase it to 60-100 psi. The packing nut might be too tight; loosen it until the valve just begins to cycle, then retighten. The micrometer adjustment might be bottomed out; back it out by turning it counterclockwise. The material might be cured in the valve; disassemble and clean the valve. Finally, the valve might have been assembled without lubricating the O-ring seals; disassemble the valve, lubricate the seals, and re-assemble.
Why is material leaking from the valve tip of my PVA FCS300 Control Unit?
If material is leaking from the valve tip of your PVA Control Unit, it could be because the packing nut is too tight; try loosening it. Also, the needle and/or seat might be worn, requiring replacement. Lastly, the seat might not be tightened enough against the fluid section; use a seat wrench to tighten the seat onto the fluid section (FCS300).
How to troubleshoot a poor spray pattern in my PVA FCS300 Control Unit?
If you're experiencing a poor spray pattern with your PVA Control Unit, it may be due to dried material at the tip of the needle and seat; remove the air cap and clean the tip. Also, check for dried material in the air cap and clean it if necessary. Incorrect atomizing air pressure can also cause this issue, so adjust it accordingly. Lastly, damaged needle and or seat can result in a poor spray pattern, so replace parts as necessary.
Why is my PVA FCS300 Control Unit valve leaking from the mid-section?
If your PVA Control Unit valve is leaking from the mid-section, it could be because the packing nut is loose; tighten it until it's snug. Alternatively, the packing might be worn, in which case you should replace it.
Why am I seeing cob webbing when using my PVA Control Unit?
If you are seeing cob webbing during spraying with your PVA Control Unit, it could be due to several reasons. The atomizing air pressure might be too high; try reducing it. The valve head might be too close to the substrate; move the valve head away from the substrate. Finally, there might not be enough solvent mix in the coating; re-examine the solvent mix ratio.
How to decrease the spray rate on a PVA FCS300 Control Unit?
If the spray rate of your PVA Control Unit is too fast, it's likely that the micrometer adjustment is set out too far. To correct this, turn the micrometer adjustment bolt clockwise toward the zero mark.
How to increase the spray rate on a PVA FCS300?
If the spray rate of your PVA Control Unit is too slow, the micrometer adjustment bolt might be set too close to the zero mark. Turn the micrometer adjustment bolt counterclockwise to resolve this.
