3.2 Valve Adjustment
Shot size and bead width depend on the following factors:
1. Length of actuation, set at controller (Valve open time)
2. Material supply pressure at reservoir
3. Material viscosity
4. Diameter and type of dispensing tip
minimum suck-back
maximum suck-back
NOTICE
Turning the adjustment knob into the valve past the
minimum mark will cause the valve to remain open.
(see illustration below).
3.3 Suck-Back Adjustment
The DV-5325 Mini Spool Valve is equipped with a natural “suck-back” feature.
When closing, the valve will pull, or “suck-back” material into the material chamber thus
helping to prevent dripping. It is possible to adjust the amount of “suck-back” by turning
the adjustment knob on the back of the valve.
There are two notches in the adjustment cap that mark the maximum and minimum
“suck-back” settings.
