These models are and certified.
The fluid supply system’s main line pressures often exceed the pressure range of the gauge supplied
with regulators 214706, 243414, 255374, and 24A082. Exposing this gauge to excessive pressure can
damage the gauge, causing inaccurate readings and the needle will not return to zero.
This damage is not covered by the Graco warranty.

WARNING
PRESSURIZED EQUIPMENT HAZARD
Spray from the gun, hose leaks, or ruptured components can splash fluid in the eyes or on the skin
and cause serious injury.
Do not stop or deflect fluid leaks with your hand, body, glove, or rag.
Follow the Pressure Relief Procedure on page 8 whenever you: are instructed to relieve the
pressure; stop spraying; clean, check, or service the equipment; and install or clean the fluid
nozzle.
Tighten all the fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
Permanently coupled hoses cannot be repaired; replace the entire hose.
INSTRUCTIONS
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture, malfunction, or start unexpectedly and result
in a serious injury.
This equipment is for professional use only.
Read all the instruction manuals, tags, and labels before operating the equipment.
Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco
distributor.
Do not alter or modify this equipment. Use only genuine Graco parts and accessories.
Check the equipment daily. Repair or replace worn or damaged parts immediately.
Do not exceed the maximum working pressure of the lowest rated system component.
Use fluids that are compatible with the equipment wetted parts. See the Technical Data section of
all the equipment manuals. Read the fluid manufacturer’s warnings.
Never use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or
fluids containing such solvents in these regulators. In the event that there is a diaphragm failure, a
serious chemical reaction could occur, with the possibility of explosion.
Route the hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not
expose Graco hoses to temperatures above 180F (82C) or below –40F (–40C).
Never kink or over bend the hoses or use the hoses to pull equipment.
Comply with all applicable local, state, and national fire, electrical, and other safety
regulations.

Installation
Fluid pressure regulators are used for accurate, posi-
tive control of the fluid pressure to spray guns, dis-
pensing valves or atomizing heads.
Regulators installed at circulating line take-offs or
pumps are used to reduce main line pressure and
maintain the desired fluid pressure to the spray gun or
atomizing head.
Before Installing the Fluid Regulator
1. Determine where to locate the regulator.
2. Install a ball valve for the regulator inlet and outlet.
3. Install temporary plumbing between the ball
valves.
4. Thoroughly flush the system to remove metal
chips and other contaminants and to check for
leaks.
Installing the Fluid Regulator
1. Remove the temporary plumbing and install one
regulator for each spray gun. See the Dimension-
al Drawing on page 21 for regulator dimensions.
Mount the regulator in a vertical position, as shown
in Figs. 1 and 2, for the best flow and minimum
pigment settling. The gauge, if used, must be
mounted vertically. If the regulator is mounted
horizontally, an elbow must be used so the gauge
will be vertical.
2. Put sealer on threaded connections, except on the
swiveling end of swivel unions as it interferes with
the swivel action.
3. Flush and test the entire system. Be sure to follow
the flushing procedure on page 8.

Operation
CAUTION
The new system must be cleaned and tested
thoroughly before admitting fluid to the regulator
to avoid contaminants clogging or damaging the
regulator.
Always use the lowest possible air and fluid
pressures for your application. High pressures
cause premature spray nozzle and pump wear.
NOTE: Reference numbers and letters in parentheses
in the text refer to the Figs. and Parts Drawing.
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
Read warnings, page 5.
1. Shut off the pump.
2. Close the fluid regulator’s inlet ball valve. Refer to
Figs. 1 and 2.
3. Relieve fluid pressure in the fluid regulator by
triggering the spray gun.
Flushing Procedure
Flush before changing colors, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1. Record the pressure adjustment setting of the fluid
regulator before flushing.
2. Shut off the pump and relieve fluid pressure in the
system by triggering the gun and opening the back
pressure regulator or other bypass valve.
3. Never exceed the maximum working pressure of
the lowest rated system component. Remove the
gauge if the flushing pressure will exceed the
gauge range.
4. Open the fluid regulator fully.
a. Spring Operated Regulators Only (see Fig. 3).
The regulator can be fully opened in two ways:
Using the male end (B) of the regulator
key (24), turn the socket–head adjustment
screw (19) fully counterclockwise. The
pressure setting will be retained.
Using the female end (A) of the regulator
key (24), turn the adjustment screw (12)
fully clockwise. You will have to reset
pressure after flushing.
b. Air Operated Regulator Only. The regulator
can be fully opened in two ways:
Close the outlet valve at the air regulator
and open the air regulator bypass valve, to
supply air directly to the fluid regulator; do
not exceed the maximum rated air pres-
sure of the fluid regulator. Pressure setting
of the fluid regulator will be retained using
this method.
Increase the air regulator setting to fully
open the fluid regulator. You will have to
reset the fluid regulator’s pressure setting
after flushing.
5. Supply solvent to the system. Set pump to the
lowest possible pressure, and start pump.
6. Flush until thoroughly clean.

Operation
7. Adjust the fluid regulator to the desired setting.
a. Spring Operated Regulators Only (see Fig. 3).
The regulator can be adjusted in two ways:
Using the male end (B) of the regulator
key (24), turn the socket–head adjustment
screw (19) fully clockwise. Verify that the
pressure setting has not changed.
Using the female end (A) of the regulator
key (24), turn the adjustment screw (12)
counterclockwise to return to the desired
pressure setting.
b. Air Operated Regulator Only. The regulator
can be adjusted in two ways:
Close the air regulator bypass valve and
open the outlet valve at the air regulator.
Verify that the pressure setting has not
changed.
Adjust the air regulator to return to the
desired fluid pressure setting.
Regulating Fluid Pressure
Spring Operated Regulator
1. Close the regulator: engage the female end (A) of
the key (24) with the adjusting screw (12) and turn
it counterclockwise to relieve the spring tension.
See Fig. 3.
2. Start the pump and open the fluid regulator’s inlet
ball valve to admit fluid to the regulator. See Fig. 1.
3. Turn the key (24) clockwise to increase fluid pres-
sure. See Fig. 3. Adjust for the desired spray
pattern.
NOTE: If using a fluid pressure gauge, reduce the
regulator pressure before partially relieving pressure in
the gun hose, to ensure a correct gauge reading. Then
increase regulator pressure to the desired setting.
Air Operated Regulator
1. Start the pump and open the fluid regulator’s inlet
ball valve to admit fluid to the regulator. See Fig. 2.
2. Increase the air pressure to obtain the desired fluid
pressure. Adjust for the desired spray pattern.
NOTE: If using a fluid pressure gauge, reduce the
regulator pressure before partially relieving pressure in
the gun hose, to ensure a correct gauge reading. Then
increase regulator pressure to the desired setting.
NOTE: Make sure the air bleed hole in the air line
fitting (29) is not plugged. Refer to page 12.
For the best results, use an air regulator with at least a
2 in. (51 mm) diameter diaphragm to control this fluid
regulator.
