WARNING  
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.

Introduction  
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.  
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.  
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 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.  
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.

Operation  
Operation  
Flush Before First Use  
Adjusting the Regulator  
Your pressure regulator has been tested in the factory  
with an anti-corrosion liquid. Before using the regulator,  
thoroughly flush the system with a solvent to remove  
residue of this liquid as well as any contaminants that  
have been introduced during assembly of the system.  
The fluid pressure regulator controls pressure down-  
stream from its outlet. The inlet fluid pressure should  
always be higher than the outlet fluid pressure.  
If you are using an accessory fluid pressure gauge, trig-  
ger the spray gun to relieve pressure in the line when  
reducing the pressure, to ensure a correct gauge read-  
ing.  
Pressure Relief Procedure  
Adjust the pump air pressure and the fluid pressure reg-  
ulator for the best spraying combination.  
WARNING  
In a circulating system, the back pressure valve controls  
the fluid pressure upstream of its inlet in the same way.  
The system pressure must be manually relieved to  
prevent the system from starting or spraying acciden-  
tally. To reduce the risk of an injury from accidental  
spray from the gun, splashing fluid, or moving parts,  
follow the Pressure Relief Procedure whenever you:

check or service any of the system equipment  
or install or clean the spray tip.  
3. Turn the knob clockwise to adjust fluid pressure to  
the desired level.  
1. Lock the gun trigger safety.  
Pneumatic Regulator  
1. With the fluid supply shut off, turn on the air pres-  
sure to the regulator.  
2. Close the bleed-type master air valve (required in  
your system).  
2. Turn on the fluid supply, to admit fluid to the regula-  
tor.  
3. Unlock the gun trigger safety.  
4. Hold a metal part of the gun firmly to the side of a  
grounded metal pail and trigger the gun to relieve  
pressure.  
3. Increase the fluid inlet pressure. When the fluid out-  
let pressure is at the desired level, shut off the air to  
the fluid regulator.  
5. Lock the gun trigger safety.  
6. Open the drain valve (required on your system), with  
a container ready to catch the drainage.  
7. Leave the drain valve open until you are ready to  
spray again.  
If you suspect that the spray tip or hose is completely  
clogged or that pressure has not been fully relieved after  
performing steps 1 through 7, very slowly loosen the tip  
guard retaining nut or hose end coupling and relieve  
pressure gradually. Then loosen completely and clear  
the tip or hose.

extended periods. Fluid could dry on the plunger and  
cause leakage at the plunger packings. If leakage  
occurs, disassemble and clean the regulator.  
WARNING  
Cleaning and Repair  
When changing fluids or colors, the regulator should be  
disassembled and cleaned. Regular cleaning and  
inspection of the internal parts is necessary to keep the  
fluid regulator working properly.  
The system pressure must be manually relieved to  
prevent the system from starting or spraying acciden-  
tally. Fluid under high pressure can be injected  
through the skin and cause serious injury. To reduce  
the risk of an injury from fluid injection, splashing fluid,  
or moving parts, follow the Pressure Relief Proce-  
dure whenever you:  
1. Relieve all air and fluid pressure in the system.  
2. Remove the regulator from the system.  
are instructed to relieve the pressure  
stop spraying  
check or service any of the system equipment  
or install or clean the spray tip.  
3. Disassemble the regulator (see the parts drawings  
on pages 16 through 22).  
4. Clean and inspect all parts.  
1. Relieve the pressure.  
CAUTION  
2. Remove the spray tip. Clean the tip and set it aside.  
Be very careful when handling the carbide balls and  
seats. Damage will cause poor operation and leak-  
age.  
3. Supply solvent to the pump. Start the pump. Use the  
lowest possible fluid pressure when flushing.  
4. Flush the gun, spraying into a grounded metal con-  
tainer until clean solvent comes from the gun.  
5. Inspect the diaphragm, packings, o-rings, and seals  
for wear. Check the ball and seat for nicks, wear, or  
other damage.  
5. Relieve the pressure.  
6. Reinstall the spray tip.  
6. Lubricate packings, o-rings and seals when reas-  
sembling the regulator.
