Warning

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 point the gun at anyone or at any parts of the body.

Do not stop or deflect leaks with your hand, body, glove, or rag.

Follow the Pressure Relief Procedure on page 11 whenever you are instructed to relieve pressure;

stop spraying; clean, check, or repair the equipment; and install or clean the spray nozzle.

•

Tighten all 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.

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.

Introduction

A fluid pressure regulator is used in air spray systems to

ensure accurate, positive control of fluid pressure to an

air spray gun or to a low pressure dispensing valve or

atomizing head.

Fluid Pressure Regulators

Models 233757, 233759, 233774, 234263, 234267, and

234273 (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 air spray gun or to a low pressure dis-

pensing valve or atomizing head.

Models 233773, 233809, 234256, and 234272 (FIG. 3.)

are pneumatically operated fluid pressure regulators

designed primarily for use with highly viscous coatings.

Back Pressure Regulators

Models 233810, 233811, 233812, 233950, 234255,

234257, 234258, 233758, 234261, and 234262, are

back pressure regulators that limit the supply pressure

to a set value by opening an outlet and guiding back

excess material when the predetermined pressure has

been achieved. These valves are used in circulating

systems. Model 233810 pneumatic back pressure regu-

lator is shown in FIG. 1.

Installation

1. Install one regulator for each spray gun.

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.

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.

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.

Operation

Mechanical Regulator

Flush Before First Use

1. Back out the adjustment screw until there is no

spring pressure.

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.

2. Turn on the fluid supply, to admit fluid to the regula-

tor.

3. Turn the screw clockwise to adjust fluid pressure to

the desired level.

Pressure Relief Procedure

Pneumatic Regulator

1. With the fluid supply shut off, turn on the air pres-

sure to the regulator.

WARNING

2. Turn on the fluid supply, to admit fluid to the regula-

tor.

Read the warnings on page 5, and follow the Pressure

Relief Procedure below whenever you:

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.

•

are instructed to relieve pressure

stop spraying

check or service any of the equipment

install or clean the fluid nozzle.

1. Shut off the air to the pump.

2. Trigger the air spray gun to relieve the fluid pres-

sure.

3. Open the fluid drain valve to relieve all fluid pres-

sure, having a container ready to catch the drain-

age.

Adjusting the Regulator

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 air spray gun to relieve pressure in the line when

reducing the pressure, to ensure a correct gauge read-

ing.

Adjust the pump air pressure and the fluid pressure reg-

ulator for the best spraying combination.

In a circulating system, the back pressure valve controls

the fluid pressure upstream of its inlet in the same way.

309474K

Troubleshooting

Relieve the pressure (page 11) before checking or repairing the equipment.

To repair the regulator, refer to page 13.

Problem

Cause

Solution

Replace diaphragm.

Drop in fluid outlet pressure.

Ruptured diaphragm (15).

Air escaping (pneumatic regulators

only).

Check air hose and connections.

Replace piston seal (21).

Fluid outlet pressure increases to

level of fluid inlet pressure.

Valve ball (5) and seat (2) are worn

or stuck open.

Clean ball and seat. Replace worn or

damaged parts.

Fluid leaking from upper housing.

Ruptured diaphragm (15).

Replace diaphragm.

309474K

Maintenance

1. Relieve all air and fluid pressure in the system.

Flushing

2. Remove the regulator from the system.

Flush before changing colors, at the end of the day,

before storing, and before repairing the equipment.

3. Disassemble the regulator (see the parts drawings

on pages 14 through 19).

Flush with a fluid that is compatible with the fluid you are

pumping and with the wetted parts of your system.

Check with your fluid manufacturer or supplier for rec-

ommended flushing fluids and flushing frequency.

Relieve the pressure after flushing.

4. Clean and inspect all parts.

CAUTION

Do not allow paint or solvent to sit in the system for

extended periods. Fluid could dry in the regulator and

cause leakage. If leakage occurs, relieve pressure, then

disassemble and clean the regulator.

Be very careful when handling the carbide balls and

seats. Damage will cause poor operation and leak-

age.

5. Inspect the diaphragm, packings, o-rings, and seals

for wear. Check the ball and seat for nicks, wear, or

other damage.

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.

6. Lubricate packings, o-rings and seals when reas-

sembling the regulator.
