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 atomizing head.

Models 233771, 233772, 234268 and 234269 (F 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 predetermined pressure has been achieved. These valves are used in circulating systems.

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.

IG. 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 requirements.

Operation

Flush Before First Use

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.

Pressure Relief Procedure

WARNING

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. 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:

• are instructed to relieve the pressure

• stop spraying

• check or service any of the system equipment

• or install or clean the spray tip.

Adjusting the Regulator

The fluid pressure regulator controls pressure downstream 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, trigger the spray gun to relieve pressure in the line when reducing the pressure, to ensure a correct gauge reading.

Adjust the pump air pressure and the fluid pressure regulator 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.

Mechanical Regulator

1. Back out the knob until there is no spring pressure.

2. Turn on the fluid supply, to admit fluid to the regulator.

3. Turn the knob clockwise to adjust fluid pressure to the desired level.

1. Lock the gun trigger safety.

2. Close the bleed-type master air valve (required in your system).

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.

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.

Pneumatic Regulator

1. With the fluid supply shut off, turn on the air pressure to the regulator.

2. Turn on the fluid supply, to admit fluid to the regulator.

3. Increase the fluid inlet pressure. When the fluid outlet pressure is at the desired level, shut off the air to the fluid regulator.

Maintenance

Flushing

WARNING

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. 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:

• are instructed to relieve the pressure

• stop spraying

• check or service any of the system equipment

• or install or clean the spray tip.

1. Relieve the pressure.

2. Remove the spray tip. Clean the tip and set it aside.

3. Supply solvent to the pump. Start the pump. Use the lowest possible fluid pressure when flushing.

Do not allow paint or solvent to sit in the system for extended periods. Fluid could dry on the plunger and cause leakage at the plunger packings. If leakage occurs, disassemble and clean the regulator.

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.

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

2. Remove the regulator from the system.

3. Disassemble the regulator (see the parts drawings on pages 16 through 22).

4. Clean and inspect all parts.

CAUTION

Be very careful when handling the carbide balls and seats. Damage will cause poor operation and leakage.

4. Flush the gun, spraying into a grounded metal container until clean solvent comes from the gun.

5. Relieve the pressure.

6. Reinstall the spray tip.

5. Inspect the diaphragm, packings, o-rings, and seals for wear. Check the ball and seat for nicks, wear, or other damage.

6. Lubricate packings, o-rings and seals when reassembling the regulator.

7. Torque as specified on the parts drawings on pages 16 through 22
