6. Attached each assembled tie rod (8) to the input
side of the adapter connector and hand-tighten with
no gaps in the tie rods.
7. Lubricate the seal (3) of the first valve assembly and
insert it in the adapter connector’s (7) input port.
8. Slide the first valve assembly along the tie rods (8)
snap the valve assembly’s fluid outlet into the
adapter connector’s (7) input port.
9. Repeat steps 7 and 8 for each valve assembly.
10. Attach the end block (6) to the ends of the tie rods
(8) and secure with the two screws (9). Torque to 35
in-lbs (4.0 N•m).
Insert Additional Valves in a Color Change
Stack
1. Repeat steps 1 and 2 of Assemble a Color
Change Stack , page 12, for each new color change
valve.
2. Loosen remove the screws (9) securing the end
block (6) and remove the block.
3. Slide off enough valve assemblies from the tie rods
(8) to make room for the new valve assembly.
4. Attach the tie rod segments for each new valve
assembly to the ends of the assembled tie rods (8)
and hand-tighten with no gaps in the tie rods (8).
5. Repeat steps 7 and 8 of Assemble a Color
Change Stack , page 12, for each new color change
valve.
6. Slide on any remaining valve assemblies on the tie
rods (8).
7. Attach the end block (6) to the ends of the tie rods
(8) and secure with the two screws (9). Torque to 35
in-lbs (4.0 N•m).
Connect Air and Fluid Tubes
1. Connect 5/32 in. (4 mm) OD air actuation tubes
from the valve solenoids to the air inlets (A) of each
valve. (See F
IG
. 2.)
NOTE: The color change valve uses a spring-operated
valve closure vent (20) that does not require a second
air actuation line.
2. Connect fluid supply lines (E) to the Quick Socket
fitting inlet port (B) of each valve adapter, and the
solvent supply line (F) to one valve (S) at the top of
the stack.
NOTE: For paint circulating systems: The color change
valves have two fluid ports for each individual valve. If
you are circulating paint, use one port for the inlet and
the other for the outlet. For paint non-circulating
systems: The color change valve has one fluid inlet port
(B).
3. Connect the gun fluid supply line to the Quick
Socket fluid outlet port (C) of the color change
manifold.
NOTE: A check valve is recommended at the inlet of all
valves to prevent backflow if a valve fails, and to prevent
color crossover if two valves are actuated at the same
time.
