Pressure Control

ENG

The Evenflo

R

Automatic Pressure Control prevents initial surging when the gun is triggered, permitting the operator to maintain a perfectly even spray coating. The control admits air to the pump as the gun is triggered, and shuts off and exhausts air from the pump as the gun trigger is released. With the pump’s relax-a-valve in the automatic position (see separate pump instruction manual), the exhausting air opens the relax-a-valve, permitting material to discharge through the drain back tube until pressure in the hose and pump is relieved.

175 psi (12 bar) Maximum Working Pressure

Installation

Note: Numbers and letters in parenthesis in the text refer to callouts in Fig. 1 and the parts drawing.

b.

To mount the Evenflo

R

Control directly to a covered drum, remove the screw (31) and lockwasher (32) from the control (1), and mount it directly to the cover

1.

Mount the Evenflo

R

Control. (See Fig. 1.)

2.

Connect the ball valve (26) and the air supply hose (24) to the right hand regulator (A). Connect the other end of the hose to the pump’s air inlet.

a.

To mount the Evenflo

R

Control to the pump, use screws (28) to attach the mounting plate

(38) to the pump base. Remove the screw (31) and lockwasher (32) from the control (1), and position the control over the small hole of the plate. Secure the control to the plate with the screw and lockwasher.

3.

Connect an air supply hose to the 1/2 npt(f) air inlet fitting (35).

4.

Connect an air atomizing hose (C) between the 3/8 npt(f) swivel union of the left hand regulator (B) and your spray gun.

Operation

Since this control will function only as part of the complete spray outfit, the operation of the Evenflo

R valve is explained in the instruction manual for the complete spray outfits

By-pass Valve Adjustment

1.

With the air supplied to the pump and the spray gun, and the pump relax-a-valve set in the automatic position, open the by-pass valve (2) four full turns from the closed position. See Fig. 1.

Note: When spraying light fluids, the ball valve (26) , may be used to regulate the pump speed. Adjust the right hand air regulator (A) to a higher pressure than necessary to operate the pump and regulate the speed of the pump by the operation of the ball valve handle.

The ball valve also provides a quick shutoff to the air pump.

2.

Point the spray gun into the drum and trigger the gun. If the pump does not operate, release the trigger and close the by-pass valve 1/4 turn.

3.

Repeat this process until the pump operates when the gun is triggered.

Troubleshooting

Note: Check all possible solutions before disassembling the control.

Problem

The Evenflo

R

delivers an insufficient air to the pump when the spray gun is open.

Probable Cause

The air supply is insufficient.

Air escapes continuously through the exhaust port while the gun is open.

The unloading action is sluggish.

Remedy

Check the hose for obstructions or leaks.

The right-hand regulator is set too low.

The right-hand regulator is inoperative.

The by-pass valve is open too far.

The left-hand air regulator is set too low.

Open the master air valve. Remove, clean and oil the filter screen.

Loosen the locknut and turn the regulator T-handle clockwise to increase pressure.

See manual 308167 for air regulator service.

Adjust, as explained on page 4.

Loosen the locknut, and turn the regulator T-handle counterclockwise to decrease pressure.

The left-hand regulator is inoperative.

See manual 308167 for air regulator service.

The atomizing air hose is clogged.

Clear.

The ball valve is set too lean.

The valve seal, seat, stem, or spring in broken or worn.

Open.

The air hose to the pump is clogged. Clear.

The Evenflo

R

valve is inoperative.

Oil the filter screen and service.

Replace.

The air pressure drops excessively

The small hole in the piston (19) is clogged.

The piston or o-ring (9) is seized.

Service.

The by-pass valve is turned too far inward.

The filter screen is clogged.

Service.

Adjust.

The main air pressure is too low.

Remove, clean, and oil the filter screen.

Check air supply.

The by-pass valve is closed too far.

Adjust.

306479 5

Daily Maintenance

Relieve the air pressure to the Evenflo

R

, and shut off the main valve. Each day, clean the filter screen (10) and add light oil to the filter cavity in the housing (13).

See the parts drawing on page 7.

Evenflo

R

Valve Service

1.

Unscrew the cap (20) from the housing (13) and remove the spring (12). Place a screwdriver in the slot of the stem (14) and unscrew the nut (3) from the opposite end. See the parts drawing on page 7.

2.

Grip the flats on the nose of the piston (19) with pliers and pull the piston out from the housing, freeing the seal (23).

Service

3.

Disassemble the valve; clean the valve thoroughly in a non-flammable solvent, and blow-dry the valve. Inspect all parts for wear or damage.

Inspect the rubber seat (15). Do not remove the seat (unless replacement is necessary. If the seat must be replaced, tuck the new seat into the housing with a smooth blunt instrument, being careful not to damage it. Pay special attention to the housing at points of contact with the piston seal (9), the valve seal (23), the plunger valve (16), and the stem (14).

4.

Lubricate the inner parts and surfaces with light oil, and reassemble the valve in reverse order of disassembly.
