Installation

Fluid pressure regulators (A) are used for accurate, positive control of the fluid pressure to spray guns (M), dispensing valves or atomizing heads.

Regulators installed at circulating line take-offs or with pumps are used to reduce main line pressure and maintain the desired fluid pressure to the spray gun or atomizing head.

NOTE: Reference numbers and letters used in the text refer to Figs. 1 and 2 and the Parts Drawings on pages

9 and 10.

Before Installing the Fluid Regulator

1.

Determine where to locate the regulator (A). See

Fig. 1.

2.

Install a ball valve at the regulator fluid inlet (C) and outlet (D).

3.

Install another bleed valve (J) upstream from all other air line accessories, to isolate the accessories for servicing.

4.

Provide an air filter (F) to eliminate moisture and harmful contaminants from the compressed air supply.

5.

Use air regulators (G, H) to control the air pressure to the gun and fluid regulator. The fluid output pressure of the fluid regulator is the same as the air input pressure set on the air regulator (H).

6.

Install air shutoff valves (W) on the air supply lines to the gun and dump valve pilot.

7.

On regulators with a dump valve, connect a

5/32 in. O.D. air line tube from the dump valve pilot

(T) to the air inlet fitting on the dump valve (B).

Connect a fluid dump line (V) to the 1/8 npt(f) port of the dump valve. Place the free end of the dump line in a properly grounded container to catch the fluid.

3.

Install temporary plumbing between the inlet and outlet ball valves.

4.

Thoroughly flush the system to remove metal chips and other contaminants and to check for leaks.

Installing the Fluid Regulator

1.

Remove the temporary plumbing and install one regulator (A) for each spray gun (M). See Dimen-

sions, page 12, for regulator dimensions. Mount the regulator with the fluid outlet at the bottom, for the best flow and minimum pigment settling.

2.

Install a bleed-type master air valve (J) in the air supply line (K) to the fluid regulator, to relieve air pressure in the fluid regulator after the air regulator

(H) is shut off.

8.

Install a back pressure valve (R) to maintain constant back pressure in the return line (P).

9.

Connect the fluid supply line (S) to the regulator’s swivel inlet (3). Connect the gun fluid supply line

(N) to the regulator’s angled fluid outlet (5).

10. Put pipe thread sealant on threaded connections, except on swivel unions; sealant interferes with the swivel action.

11. Flush and test the entire system. Be sure to follow the flushing procedure on page 5.

4 308292

Operation

Regulating Fluid Pressure

CAUTION

D The new system must be cleaned and tested thoroughly before admitting fluid to the regulator to avoid contaminants clogging or damaging the regulator.

D Always use the lowest possible air and fluid pressures for your application. High pressures cause premature spray nozzle and pump wear.

1.

Start the pump and open the fluid regulator’s inlet ball valve (C) to admit fluid to the regulator. See

Fig. 1.

2.

Increase the air pressure to obtain the desired fluid pressure. Before reducing the regulator pressure, partially relieve pressure in the gun fluid supply hose to ensure the correct gauge reading.

NOTE: Reference numbers and letters used in the text refer to Figs. 1 and 2 and the Parts Drawings on pages

9 and 10.

NOTE: For the best results, use an air regulator with at least a 2 in. (51 mm) diameter diaphragm to control this fluid regulator.

Pressure Relief Procedure

Using the Dump Valve

WARNING

To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pres-

sure Relief Procedure whenever you:

D are instructed to relieve the pressure,

D Clean, check, or service any of the system equipment,

1.

Shut off the fluid supply to the regulator.

2.

Trigger the dump valve pilot (T). The valve will open and relieve fluid pressure in the regulator.

Flushing Procedure

1.

Flush the regulator with a compatible solvent whenever the rest of the system is flushed.

1.

Shut off the pump.

2.

Close the fluid regulator’s inlet ball valve. Refer to

Fig. 1, page 3.

3.

Relieve all fluid and air pressure in the fluid regulator.

2.

Remove the gauge if the fluid pressure will exceed the gauge range.

3.

Flush until thoroughly clean. Always use the lowest possible pressure when flushing.
