Installation

Fluid pressure regulators are used for accurate, posi­tive control of the fluid pressure to spray guns, dis­pensing 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.

7307212

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. 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.

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.

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 pres­sure 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.

8 307212

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.

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.

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

Graco Standard Warranty

Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the
date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco,
Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub­stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.

Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection
with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured
by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide
purchaser with reasonable assistance in making any claim for breach of these warranties.

In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
