Connect Circulating Fluid Lines

Circulation valves enable constant circulation of a color when that color is not being sprayed:

•When a color valve is closed, the system bypasses the dosing pump by directing that color from the inlet color valve to the outlet color valve to the remote color valve, through a circulation line, then back to the color supply.

•When a color valve is open, the circulation line is shut off. The color is directed through the material A dosing pump and out to the remote color valve stack and mix manifold, as in normal operation.

NOTE: On circulating systems, install a cap (T) on any unused valve ﬁttings.

NOTE: There can be only one solvent valve (S) and one dump valve (D) per pump.

NOTE: On high pressure systems, see

Install the Back Pressure Regulator (High Pressure Systems Only), page 21.

1.Connect all ﬂuid lines as described in Connect Non-Circulating Fluid Lines, page 26. These lines are used during normal mixing and spraying.

2.Connect the circulation lines as follows:

a.Connect a 1/4 npt(f) circulation line for each color from the color valve’s circulation ﬁtting (R1, R2, etc.) on the inlet color valve stack

(B)to the corresponding circulation ﬁtting (R1, R2, etc.) on the outlet color valve stack (C). This circulation line bypasses the material A dosing pump when the color valve is closed, allowing continuous circulation of that color.

b.Connect a dedicated ﬂuid supply line for each color to the corresponding color valve (C1, C2, etc.) on the outlet color valve stack. Connect the other end of each line to the corresponding color valve on the remote color stack.

c.Connect a 1/4 npt(f) circulation line from the circulation port on each remote valve back to the ﬂuid supply container.
