Metering Air Valve Troubleshooting Instructions
(Figure 13c)
How They Work
Refer to Figure 13c.
1. A pulse of air is created at the air diaphragm by pressing the pushbutton.
2. The pulse of air travels through the 1/8" air tubing into the lower port on the valve, up through
the magnet (housed within Item 9) and diaphragm, and exits through the top cover of the valve.
3. Releasing the pushbutton draws all the air out of the valve creating a vacuum inside the valve.
4. The top diaphragm acts as a check and does not let any air enter the valve through the top cover.
5. The vacuum created allows the magnet to drop down in the valve, attracting the armature plate.
6. The rising armature plate allows the water pressure to push the seat diaphragm off the valve
seat.
7. Water flows through the seat and out to the sprayhead.
8. Air is pulled into the valve through the timer by the vacuum on the inside of the valve.
9. The incoming air breaks the vacuum on the inside of the valve (Item 9).
10. The amount of air entering the valve through the timer determines the metering cycle.
11. When the vacuum is eliminated, the magnet spring pushes the magnet back to its original posi-
tion.
12. The armature plate drops down to its original position, pushing the seat diaphragm back down
on the seat closing the valve.
13. A small amount of water passes through the diaphragm to equalize the pressure on either side of
the diaphragm.
Adjust Air Valve Meter Time
NOTE: The air valve timer is located next to the tube connector on the air valve body. The timer is
capped with a filter to prevent dirt build-up on the timer. The air valve timing can be adjusting from 5–60
seconds.
1. Remove filter cap and use a screwdriver to tighten or loosen the timer (Figure 13c). Turning the
timer clockwise increases the time; turning the timer counterclockwise decreases the time.
2. Continue to adjust until the timer is set at desired length.
3. Replace filter cap over the timer.
Tube Connection Leaks
1. Push in the white manual release button while pulling the tube out (see Figure 13c) to disconnect
the tube at the tube fitting. No tools are needed.
2. To correct a leak, press tubing firmly into the tube fitting and make sure it is seated.
3. If leak persists, remove tubing from the fitting, and trim the tubing end square with a razor-sharp
knife. If leak continues, replace the fitting or contact your Bradley representative for assistance.
