Normal paint flow rate with valve activated: 150 cc/min
X: Time required for the paint to flow from the colour change block to the bell cup.
Y: Time required for paint to leave the bell cup.
Recommended solvent flow rate for injector: 300 cc/min
Recommended solvent flow rate for bell cup rinsing: 250 cc/min
Always use restrictors if the flow rate exceeds the values above.
The final pneumatic pulse clears and dries the rinsing circuit for the outside of the bell cup
in order to prevent any solvent being sprayed.
