WARNING
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
• This equipment is for professional use only.
• Read all instruction manuals, tags, and labels before operating the equipment.
• Use the equipment only for its intended purpose. If you are not sure, call your Graco distributor.
• Do not alter or modify this equipment. Use only genuine Graco parts and accessories.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not exceed the maximum working pressure of the lowest rated system component. Refer to the
Technical Data on page 24 for the maximum working pressure of this equipment.
• Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Techni-
cal Data section of all equipment manuals. Read the fluid and solvent manufacturer's warnings.
• Route 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).
• Wear hearing protection when operating this equipment.
• Never use 1,1, 1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or flu-
ids containing such solvents in pressurized aluminum equipment. Such use could result in a chemi-
cal reaction, with the possibility of explosion.
• Comply with all applicable local, state, and national fire, electrical, and safety regulations.
Warning
309475F 5
SKIN INJECTION HAZARD
Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an
extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can
also cause serious injury.
• Fluid injected into the skin might look like just a cut, but is a serious injury. Get immediate surgical
treatment.
• Do not point the gun at anyone or at any part of the body. Do not put your hand or fingers over the
spray tip. Do not stop or deflect fluid leaks with your hand, body, glove, or rag.
• Never spray without the tip guard in place.
• Follow the steps under Pressure Relief Procedure, page 13, when you stop spraying and before
cleaning, checking, or repairing equipment.
• Check the hoses and couplings daily. Replace worn, damaged, or loose parts immediately. Perma-
nently coupled hoses cannot be repaired; replace the entire hose.
• Tighten all fluid connections before each use.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.
• Know the specific hazards of the fluid you are using. Read the fluid manufacturer’s warnings.
• Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
• Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.
WARNING
Introduction
6309475F
Introduction
A fluid pressure regulator is used in air-assisted spray
systems to ensure accurate, positive control of fluid
pressure to a spray gun, dispensing valve, or atomizing
head.
A regulator installed at a circulating line take-off or pump
reduces main line pressure to maintain the desired fluid
pressure to the spray gun, dispensing valve, or atomiz-
ing head.
Models 233771, 233772, 234268 and 234269 (FIG. 1.)
are mechanically operated back pressure regulators that
limit the supply pressure to a set value by opening an
outlet and guiding back excess material when the prede-
termined pressure has been achieved. These valves are
used in circulating systems.
Models 233767, 233814, 233768, 234260, 234264, and
234265 (FIG. 2.) are mechanically operated fluid pres-
sure regulators designed primarily for use with low to
medium viscosity fluids.
Models 233760, 233769, 233770, 233813, 234259,
234266, 234270, and 234271 (FIG. 3.) are pneumati-
cally operated fluid pressure regulators designed pri-
marily for use with highly viscous coatings.

Installation
1. Install one regulator for each spray gun.
2. Apply thread sealant to connections as necessary.
3. Make sure that the direction of fluid flow agrees with
the flow direction markings on the regulator body.
a. Install a fluid pressure regulator upstream of the
gun: Connect the fluid line from the pump to the
inlet of the fluid regulator. Connect the fluid line
to the gun to the regulator’s outlet.
b. Install a back pressure regulator downstream of
the gun. Connect the fluid return line from the
gun to the inlet of the back pressure regulator.
Connect the fluid return line to the pump to the
regulator’s outlet.
4. Flush and test the entire system.
FIG. 4., FIG. 5., and FIG. 6. show possible configurations
for installing a system. They do not depict actual system
designs. Consult your Graco distributor for assistance in
designing a system that meets your specific require-
ments.
