WARNING
WARNING
SKIN INJECTION HAZARD
Fluid from the dispensing valve, leaks, or ruptured components can inject fluid into your body and
cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on
the skin can also cause serious injury.
D Fluid injected into the skin may look like just a cut, but it is a serious injury. Get immediate
surgical treatment.
D Do not point the dispensing valve at anyone or at any part of the body.
D Do not put your hand or fingers over the end of the dispensing valve.
D Do not stop or deflect leaks with your hand, body, glove or rag.
D Use only extensions and nozzles that are designed for use with your dispensing valve.
D Do not use a low-pressure flexible extension with this equipment.
D Follow the Pressure Relief Procedure on page 9 before you clean, check, or service the
equipment.
D Tighten all fluid connections before you operate the equipment.
D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. Do
not repair high pressure couplings; you must replace the entire hose.

Installation
See manual 307965 for electronic meters installation, operation, parts, and cautions and warnings.
NOTE: Numbers in parenthesis, for example (7), and in the Parts Drawings are reference numbers
in the Parts List on page12.
Typical Installation
Fig. 1 shows a typical installation. Additionally, these
dispense valves can be installed on a console.
CAUTION
Do not use this electronic metered dispense
valve on non-Graco consoles. Such use could
result in the trigger becoming inadvertently
pressed while the dispense valve is stowed.

Installation
Pre-Installation Procedure
1. Relieve the pressure.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
2. Close the fluid shut-off valve (item J in Fig. 1).
3. Ground the hose and reel or console. See
Grounding on page 8. Do not use PTFE tape
on the pipe joints; it may cause a loss of ground
across the pipe joint.
Installation Procedure
CAUTION
If this is a new installation, or if the oil in the
lines is contaminated, flush the lines before you
install the dispensing valve.
Existing Installation
1. Relieve the pressure.
WARNING
To reduce the risk of serious injury, whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
2. Loosen and disconnect the hose from the old
dispense valve (the one that you are replacing).
For steps 3 to 5, see Fig. 2.
3. Thread the extension (26a) into the outlet of the
dispense valve, and tighten firmly.
NOTE: Do not over tighten the extension tube
assembly by using the nozzle adapter to hand turn the
nozzel. For rigid extensions, thread the extension
in at least three full turns, position the extension
for proper alignment, and tighten the sealing
nut (7). The PTFE seal on the sealing nut must
face the valve housing.
New Installation
1. Relieve the pressure.
WARNING
To reduce the risk of serious injury, whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
Steps2to6aretheFlushing Procedure.
2. Close the fluid shut-off valve (J) at each dispense
position.
3. Make sure the main fluid outlet valve at the pump
is closed, the air pressure to the pump motor is
adjusted, and the air valve is open. Slowly open
main fluid valve.
4. Place the hose end (with no dispense valve connected) into a container for waste oil. Secure the
hose in the container so it will not come out during
flushing. If you have multiple dispense positions,
first flush the dispense position farthest from the
pump, and work your way toward the pump.
4. Apply thread sealant to the male threads of the
hose fitting, thread the hose fitting into the swivel
(20), and tighten firmly.
5. Thread the new nozzle (8) or nozzle adapter onto
the extension, and tighten firmly.
6. Open all dispense position shut-off valves, and
start the pump to pressurize the syst em. See the
Operation section for proper operation.
7. For metered dispense valves, to ensure dispensing accuracy, purge all air from the fluid lines and
dispense valves before you use them.
Model shown is a V12 with
a75_ bend rigid extension.

5. Slowly open the shut-off valve (J) at the dispense
position. Flush out a sufficient amount of oil to
ensure that the entire system is clean, and close
the valve.
6. Repeat step 5 at all other dispense positions.

Grounding
Installation
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground all system
components per local and national electrical codes.
Refer to the user manuals for the pump and other
system components to ground the following:
D Pump: Follow manufacturer’s recommendations.
D Air and Fluid hoses: Use only grounded hoses.
D Air compressor: Follow manufacturer’s recommen-
dations.
D Fluid supply container: Follow your local code.
D To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
valve firmly to the side of a grounded metal pail,
then trigger the valve.

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until
pressure is manually relieved. To
reduce the risk of serious injury from
pressurized fluid, accidental spray from the
dispenser or splashing fluid, follow the PressureRelief Procedure whenever you
D Are instructed to relieve pressure
D Check, clean, or service any system equipment
D Install or clean fluid nozzles
1. Turn off the power supply to the pump.
2. Trigger the valve into a waste container to relieve
pressure.
3. Open any bleed-type master air valves and fluid
drain valves in the system.
4. Leave the drain valve open until you are ready to
pressurize the system.
If you suspect that the dispensing valve, extension, or
nozzle is clogged or that pressure has not been fully
relieved after following the steps above, very slowly
loosen a fitting on the fluid line to relieve pressure
gradually, then loosen it completely, then clear the
clog.
WARNING
To reduce the risk of a serious bodily injury, including fluid injection, never exceed the maximum
working pressure of the valve you are using or of
the lowest rated component in your system.
Dispensing Procedure
See instruction manual 307965 for electronic meter
operation.
NOTE: Before you begin, make sure you understand
how to unlock the trigger. Model EM6 does not have
a trigger lock.
1. Pull the trigger toward the valve body to open the
valve and begin dispensing.
2. Lock the valve open by keeping the trigger
squeezed and depressing the trigger lock button
(25intheParts Drawing). Then release the
trigger, releasing your forefinger from the trigger
lock last.
3. Pull the trigger toward the valve body to release
the trigger lock. The trigger lock disengages.
4. Release the trigger to stop dispensing.
3086429
Troubleshooting
Relieve the pressure before you check or repair the
dispensing valve. Be sure all other valves and controls
and the pump are operating properly.
