YRead and heed all Warnings and Safety Precautions

before operation of this unit.

YUse only genuine ARO replacement parts to assure

compatible pressure rating and longest service life.

YBe certain anyone operating this equipment or fluid

system has been trained to use it safely.

WARNING

HIGH PRESSURE DEVICE. IMPROPER

USAGE OF THIS EQUIPMENT COULD RESULT IN

SERIOUS INJURY. The possibility of injection into

the flesh is a potential hazard. Wear approved

safety glasses or face shield and other equipment as

needed to prevent injury. Never allow any part of the

human body to come in front of or in contact with

the material outlet, the tip, or the material outlet

of the dispensing device. An injection injury can be

serious. If an injection accident should occur, it is very

important that you contact a qualified physician for

immediate treatment.

WARNING

MISAPPLICATION HAZARD. DO NOT USE

THE REGULATOR WHEN THE FLUID INLET PRESSURE

IS TOO HIGH FOR THEDESIGNED OPERATING RANGE.

Excessive inlet pressure can cause a Lock-Out

situation. Lock-Out occurs whenthe inlet pressure

isbeyondthe regulator’s springcapacity. THE

VALVE WILL NOT OPEN. Attempts to disassemble

componentswhile in a Lock-Out condition mayresult

in injury.

WARNING

COMPONENT RUPTURE. DO NOT OPERATE

REGULATOR AT AN INLET PRESSURE GREATER THAN

SPECIFIED. To avoid possible damage or personal

injury, DO NOT operate this unit at pressure higher

than the stated operating range as it appears on the

model plate.

WARNING

DISASSEMBLY HAZARD. DO NOT

DISASSEMBLE THIS REGULATOR WHEN IT IS UNDER

PRESSURE. RELIEVE PRESSURE IN THE PUMPING SYSTEM

BEFORE ATTEMPTING SERVICE OR DISASSEMBLY

PROCEDURES. Disconnect air lines and carefully bleed

pressure off the system. Be certain the system is not

maintaining pressure due to amaterial restriction in the

hose, line, dispensing device, or the spray or extrusion

tip. Failure to relieve pressure both up stream and

downstream may result in an injury upon disassembly.

WARNING

BONNET REMOVAL HAZARD. DO NOT

ATTEMPT TO REMOVE THE FOUR BONNET RETAINING

BOLTS WITHOUT FIRST RELIEVING THE TENSION ON THE

MAIN SPRING. Failure to relieve tension could result in an

accident upon disassembly.

WARNING

PREVENT FIRES. KEEP SOLVENTS AWAY

FROM HEAT, SPARKS OR OPEN FLAME. Keep containers

closed when not in use.Whenpumping, flushing or

recirculating volatile solvents, be certain the area is

adequately ventilated.

CAUTION

FLUSH SUPPLY LINE. Before installing

fluid regulator, blow the supply lines clear and flush

to remove contaminates.

OPERATING AND SAFETY PRECAUTIONS INSTALLATION

yRefer to the typical installation view which best applies.

yLocate the regulator as close as possible to the spray gun

or dispensing device for best pressure control.

yIdentify the regulator INLET / OUTLET (flow direction).

The regulator is marked with an arrow on the body base

(see gure 8).

yWhen flexible fluid lines are used, mount the regulator

securely using the (2) 1/4” - 20 threaded holes in the base

(see gure 8).

yFlush supply line before installing regulator.

OPERATING INSTRUCTIONS

Refer to page 4 and 5 for parts reference.

yTo INCREASE outlet pressure, turn the (6) adjusting screw

CLOCKWISE (see gure 4).

yTo DECREASE outlet pressure, turn the (6) adjusting

screw COUNTERCLOCKWISE (see gure 4).

NOTE: ARO Part Y106-109 Allen wrench is included to make

necessary pressure adjustments.

FLUSH-OUT FEATURE (see gure 5).

yFlush the regulator periodically. The interval may vary de-

pending on the amount and type of material used.

yBy using a wrench and “flush-out” plug (provided), the

operator is able to move the entire spindle downward

and force the ball off the seat which should purge the

regulator of particle build-up.

NOTE: The ush-out procedure temporarily overrides the

adjusted pressure. It will not, however, aect the regulator

setting when ushing operation is completed.

FLUSH-OUT PROCEDURE

1. Remove spray gun or dispensing device, this will allow

any particles to clear from the system.

2. Insert (30) flush-out plug and turn clockwise until it

touches the (4) washer (see view on page 5).

3. Turn up to two turns maximum. This will allow the ball

to unseat and pass material at free flow (unregulated).

DO NOT attempt to turn further to avoid damage.

4. Turn the plug back to its original position.

SEAT PLUG FEATURE

The (29) plug located at the base of the regulator can be

removed for access to the ball and seat assembly for clean-

ing and inspection for wear. With this feature, the regulator

REGULATOR DISASSEMBLY

FOR “WARNINGS”, REFER TO “OPERATING AND SAFETY

PRECAUTIONS” ON PAGE 2 FOR DETAILS.

BEFORE SERVICING, READ “WARNING: DISASSEMBLY

HAZARD”. FOUND ON PAGE 2.

TOOLS REQUIRED: Small bench vise, 5/32” allen wrench, 3/8”

allen wrench, torque wrench and Loctite 242.

NOTE: It is not always necessary to remove the regulator

from the uid line to service or inspect only the valve section.

BEFORE DOING ANY IN-LINE SERVICE, ALL FLUID PRES-

SURE MUST BE RELIEVED. HEED ALL WARNINGS FOUND

ON PAGE 2.

VALVE SEAT NOTE: Before deciding to order a repair kit to

service the regulator, check the easiest things rst. Remove

and inspect the valve seat for dirt, foreign matter, damage or

wear (step 1).

1. Remove the (29) seat plug and (28)“O”ring, releasing (27)

ow tube, (26) spring, (25) ball, (24) seat and (23)“O” ring.

2. Remove four (1) bolts and (2) lock washers, releasing (3)

housing.

NOTE: The (6) adjusting screw [with (8) adjustment nut], (5)

thrust bearing and (4) washer are retained by (7) plate, which

is pressed into place. It should not be necessary to disassem-

ble these parts during normal service.

3. Remove (11) plate and (10) spring from (3) housing.

4. Remove (15) cap screws, releasing (16) plate.

5. Remove the stem / diaphragm / piston assembly.

6. Place the assembly in a vise, clamping on ats of (21)

stem assembly.

7. Using a 5/32” Allen wrench, remove the (12) cap screw,

releasing (13) lock washer, (14) piston, (17 and 18) dia-

phragms and (19) “O” ring.

does not have to be unthreaded from the pumping system.

Be certain to relieve system pressure (See “WARNING: DISAS-

SEMBLY HAZARD”).

MAINTENANCE

yDisassembly should be done on a clean work bench and

use clean cloths.

yIf replacement parts are necessary, refer to the parts list

and drawings on pages 4 and 5.

yUpon reassembly, lubricate parts and use Loctite where

indicated. Follow the torque specications as shown.

yService kits are available which include parts typically

needed for an overhaul.

yKeep good records of service activity and include the

regulator in a preventive maintenance program.

yCertain ARO “Smart Parts” are indicated with a “V” in the

parts list, these parts should be available for fast repair

and reduction of down time.

TROUBLE SHOOTING

No uid pressure.

yCheck for damaged or worn diaphragms.

yLook for possible obstruction by hardened material or

foreign matter, periodically use the regulator “ush-out”

feature. Use a uid lter upstream from the regulator.

Pressure creeps above the setting when system is dead

ended and in a static (no ow) mode.

yCheck for dirty seat and clean as appropriate.

yCheck for worn or damaged seat and replace if necessary.

Outlet pressure drops below setting.

yCheck pump for proper operation and check for possible

leakage problems.

yLook for a clogged supply line problem, ush the supply

line.

Fluid leakage from spring housing.

yCheck the (1) bolts and the (15) cap screws and re-torque

as needed.

yCheck for damaged diaphragm, replace as needed.

Regulator will not function, even when dispensing de-

vice is opened.

yCheck for possible obstruction in the uid line.

yInlet pressure is too high causing a “Lock-Out” situation.
