CS-11-02.1: Inline / Piggable Dual Modular Color Changer
TEST AND CHECK OUT PROCEDURE FOR COLOR
CHANGER
Step 1: Test Setup
A. Connect a main air line to the regulator #4.
B. Attach the output of #4 to a push button, manually oper-
ated pneumatic On/Off valve #5 and #3, two-way manual
ball valve. Attach a 5/32” hose from the output of #5 to
pilot connection for the color valve.
C. Attach the output of #3 the sanitary fitting input of the
valve. Plug the opposite sanitary fitting of valve.
D. Attach pipe tee, gage, #2 and two-way ball valve assem-
bly #1 to the output of the color changer. Plug off other
side.
Step 2: Testing Color Valve Assembly
A.
Set output pressure of regulator #4 to 90-100 psi.
NOTE—Turn the shutoff valve #6 counter-clockwise to the
OPEN position.
B. With ball valves #1 and #3 in the Off position, push and
release the button on the pneumatic valve #5, triggering
the microvalve assembly (78949-00) On and Off.
C. Visually inspect the movement of the valve and check for
air leaks from the weep hole on the color valve body. If
air is leaking, repair or replace valve assembly (78949-
00). Check for leaks between the pipe/plate assembly
and color valve block. Tighten screws or replace o-ring if
necessary.
D. With ball valves #1 and #3 in the On (open) position, push
and release the button on the pneumatic valve #5 trigger-
ing the microvalve assembly (78949-00) On and Off.
Check for a crisp and sharp actuation of air flow through
the output of the #1 ball valve. If valve is sluggish, repair
or replace valve assembly (78949-00).
TEST AND CHECK OUT PROCEDURE FOR COLOR CHANGER (Continued)
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. Efficiency of the equipment will also be re-
duced and damage or failure of the equipment’s components may occur.
WRAPPING THE EQUP-
MENT
in plastic will void warranty.
WARNING
Step 3: Testing Valve Body Leak Test
A. With ball valve #3 in the On (open) position and valve #1
In the Off position, push and release the button on the
pneumatic valve #5 triggering the microvalve assembly
(78949-00) On and Off several times.
B. Check the pressure gage reading on the #2 assembly.
This should be within 5 psi of the pressure of the set pres-
sure on regulator #4. The pressure should remain until
the valve #1 is returned to the open position. If the pres-
sure does not remain, check all fittings, hardware, and o-
rings on the valve body and plate assembly.
Step 4: Testing Microvalve and Valve Seat Assemblies
A. With ball valve #1 in the On position, and valve #3 in the
On position, push and release the button on the pneu-
matic valve #5 triggering the microvalve assembly
(78949-00) On and Off several times.
B. Close the 2-way ball valve on the #1 assembly. The
pressure should remain 0 psi.
If the pressure is greater than 0 psi, the valve seat assembly
(77367-00) should be replaced.
