Explosion Hazard /
Incompatible
Materials
3
Halogenated hydrocarbon solvents for example: methylene
chloride and 1,1,1,-Trichloroethane are not chemically compatible with the aluminum that
might be used in many system
components. The chemical reaction caused by these solvents
reacting with aluminum can
become violent and lead to an
equipment explosion.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum equipment during spraying, ushing, or cleaning. Read
the label or data sheet for the material you intend
to spray. If in doubt as to whether or not a coating
or cleaning material is compatible, contact your
material supplier. Any other type of solvent may
be used with aluminum equipment.

DESCRIPTIONS
The MCV 2 Collet Series Modular Color Changer is a
material valve stack used to control material ow to
an applicator or other material supply equipment.
The stack assembly is made up of several sub-assembled stacks which are then connected together.
The assemblies are available in both Metric and
English tube sizes.
A description of stacks are as follows:
• Bell Wash Module - This may be attached
to the main stack.
• Stand-Alone Bell Wash Module - These may
be mounted separately away from the stack
assembly. An external outlet port is included
to provide a connection to an applicator or
other such device.
• Two and Four Color Block Modules. Both available in 3 styles: Circulating, Daisy Chain, and Dead Head.
• Inline DR-2 Regulator with performance
matching the industry standard
Ransburg DR-1 Regulator.
• Flow Meter Module for use with bottom
ported uid ow meters.
The 78949-00 microvalve was designed to trigger
up to 2-million cycles. The uid and air sections are
separated by a weep port to prevent contamination
between air and uid.

> The color changer MUST be properly grounded. Proper grounding (as described below)
will prevent static charge buildup and possible
discharge from the color changer.
Grounding of the Color Changer
For safety, the color changer MUST be grounded.
Using a 12-gauge wire, ground the output plate
of the color changer to a true earth ground. Using
an ohmmeter, check for ground, testing the earth
ground to the outlet. The resistance should be 10
ohms or less.

PROCEDURES
Determine Location for Color Changer
The color changer should be located as close as
possible to the spray device in order to save paint
and solvent with a color changer. If possible, use an
enclosure to protect the color changer from airborne
paints and solvents.
Calculate Footprint of Color Changer
(See Figure 3)
To calculate the footprint of the color changer add:
• The dimension of the end plate
• The dimension of the purge assembly
• The dimension(s) of the module(s) used to
create the desired number of color valves
• The dimension of the output assembly

the insert, blow compressed air in the hex end of the
insert and the carbide seat will come out.
Figure 13: Diaphragm Assembly Position
NOTE
> The seat and stem are matched sets of
parts, each having a serial number engraved
on them. Care must be taken not to mix nonmatching seats and stems or the regulator
will not perform properly.
Reassembly
1. Install all removed o-rings [9] and [4] on the
insert and the seat. Push the seat [5] into the insert
(straight in) using an arbor press if possible.
2. Insert spring [10], stem [5], and one o-ring [4]
into the regulator body [1].
3. Using a 3/16” Allen wrench, tighten the insert
down until it bottoms out.
5. Add plate [13], upper diaphragm [6], and lid
[14]. Tighten the eight (8) screws [16] in a cross
pattern to 10 lbs•in. Then follow by tightening
each screw in a circular pattern to 20 lbs•in.
4. Locate the dot on the diaphragm assembly [2]
and place it so it is 180° from the outlet hole of
the body.

TEST AND CHECKOUT
PROCEDURE FOR COLOR
CHANGER
Step 1:
1. Connect air line to a regulated air supply.
2. Attach the air line to a ball valve assembled to
the outlet of the color changer.
3. Adjust the air supply pressure to 100 psi (6.9
bar).
4. Open the ball valve at the outlet of the color
changer.
5. Apply a soap solution on the color changer
manifold.
6. Check the manifold assembly’s mating surfaces between color blocks for soap bubbles.
2. Connect the air supply hose with 100 psi
(6.9 bar) to color inlet valve. Connect a 2-way ball
valve to the matching return port on the color
changer manifold.
3. Turn the ball valve installed on the paint circulation tting to verify recirculation ability.
NOTE
> Ensure valve is closed when completed.
4. Connect the air supply with a 3-way valve
(normally closed) to the color valve cylinder.
5. Activate the 3-way valve to operate the color
valve.
NOTE
NOTE
> If bubbles are observed, dismantle color
changer manifold and repair as required.
7. If no bubbles are present, rinse manifold with
water and blow dry with air.
Step 2:
1. Attach two (2) regulated air supply hoses, one
with a 3-way valve (normally closed) for operating
the color valve cylinder on the color changer. (Set
the pressure to the 3-way valve at 75 psi
(5.8 bar) or more.)
The second hose will be used for supplying 100 psi
(6.9 bar) of air to the color inlet port of each color
changer valve.
> The piston rod on the top of the color valve
assembly should EXTEND and air should
blow out of the color changer outlet. Check
for a crisp and sharp actuation of the color
valve air cylinder.
6. Deactivate the 3-way valve and close the
color valves.
NOTE
> The piston rod on the top of the color
valve assembly should be RETRACTED, and
the air should have stopped blowing out of
the outlet of the color changer.
7. Connect a 1/4-inch (6.4cm) ID hose 3-ft.
(91.4cm) long to the outlet of the color changer.

8. Acquire a container of water and ll it with
about 4-inches (10.6cm) of WATER. Position the
hose in the container lled with water.
9. There should be no more than 6 bubbles per
minute coming from the outlet of the hose that is
submerged.
10. If there are more than 6 bubbles per minute,
remove the color valve assembly, replace the
valve seat (77367-00) and reinstall color valve
assembly. If the new seat does not correct the
problem, either the manifold block or color valve
assembly is defective.
11. Proceed to the next color valve and repeat
Steps 2 thru 11.
12. When all the color valves are checked out,
then check the purge valve assembly repeating
Steps 2 thru 11.

W A R N I N G
> NEVER wrap the equipment in plastic to
keep it clean. A surface charge may build-up
on the plastic surface and discharge to the
nearest grounded object. Eciency of the
equipment will also be reduced and damage
or failure of the equipment’s components may
occur. WRAPPING THE EQUIPMENT in plastic
will void warranty.
13. Once all valves are operational, deactivate
the 3-way valve, and then disconnect the air
lines used for testing from the color changer.
!
W A R N I N G
> ALWAYS test color changer for conductivity
after assembly or repair. Proper conductivity is
required to assure entire color changer can be
properly grounded when installed.
14. With an ohmmeter, check for conductivity
between the output plate on the color changer
and earth ground. There should be 10 ohms or less
between the two points (see Figure 14).
