Automatic Drain Valves
ADV
IM-P509-06-US February 2006
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Isolation
NOTE: If pipe thread lubricant/sealer is used on the
connections, use care in applying, as to avoid any
lubricant/sealer from entering the internals of the
ADV system.
Operation
Caution: Do not operate the ADV outside of the
following pressure and temperature ranges:
The ADV is a timed electrical device that, when
properly adjusted, automatically removes condensed
water and oil from an air reciver tank. It is a low cost,
simple device that will keep your compressed air
system running efficiently while greatly reducing
system maintenance costs.
Remove the ADV from the packaging and inspect for
any damage. Also, check the voltage rating on the coil
to confirm the correct voltage for your application.
The Product
The ADV consists of the following parts:
A) Valve
B) Coil
C) Timer
D) 6’ Powercord
E) Strainer Ball Valve.

1. Warning: Be sure the tank, has been de-
pressurized or isolated before starting.
2. Assemble the Strainer Ball Valve to the piping
eggressing from under the tank (1/2" NPT
connection required.)
3. Assemble the ADV to the Strainer Ball Valve.
Note the direction of flow on the valve body.
It should be pointing away from the tank.
4. Be sure to attach a drain line from the ADV to
control and direct the high-pressure discharge to
a safe location.
5. Plug powercord into 120V AC power supply (Other
voltages, will have a powercord with stripped and
tinned ends for assembly to their power supply.)
6. Push “test” (3) button on timer to check operation.
You are now ready to adjust system.
7. Observe all Federal, State and Local laws and
regulations when installing and operating the ADV.
Maximum Operating Pressure: 300 psig
Fluid temperature: 32 to 266°F (0 to 130°C)
Ambient temperature: -4 to 122°F (-20 to 50°C)

Adjusting
This procedure may take a number of trials to set up
correctly. The system will be functioning correctly when
the ADV opens long enough to drain almost all the
condensate from the system. Do not drain completely, as
this will drain costly compressed air.
1. Pressurize the system.
2. Set the “ON” button (1) to 10 seconds and note when
the condensate fully dispensed. Then back off by
approximately one-half second.
3. Set the “OFF” buton (2) to 5 minutes, to start. When
the ADV energizes, watch the discharge for air
escaping following the condensate discharge. Repeat
the steps outlined in 2 and 3, by adjusting the
“ON/OFF” buttons until the proper time is achieved to
effectively remove the condensate without loosing
costly air pressure.
NOTE: Changes in seasons and humidity may have an
affect on the “ON/OFF” time settings. If so readjust the
settings.
Maintenance
It is necessary to periodically clean the screen located in
the Strainer Ball Valve. Failure to do this may cause
damage to the compressed air system resulting in costly
shutdown. To do this maintenance procedure, perform
the following steps:
1. Isolate the strainer screen by rotating the blue ball
valve handle (4) 90° clockwise to the closed position.
2. Unscrew the knurled end cap and remove it along
with the stainless steel screen.
3. Clean debris from end cap and screen.
4. Place screen into end cap and screw the assembly
into Strainer Ball Valve.
5. Rotate blue handle 90° counter-clockwise to reopen
and pressurize the sytem.
Trouble Shooting
Caution: Whenever servicing the ADV, be sure to remove sytem pressure form the immediate system.
1. Valve will not close: Typically caused by particulates and debris in the valve causing the seals not to
properly close.
Action: ADV25 series and up: Remove top nut and remove the coil-timer assembly. Unscrew guide
assembly by large hex nut and remove. Use care as not to lose
plunger and spring assembly. Carefully remove diaphragm
assembly. Clean internal and parts. Reassemble in reverse order
and pressurize.
Action: ADV10 series: Remove top nut and remove the coil-timer assembly. Unscrew
stainless steel stop from atop brass guide with pliers. Carefully
remove plunger and return spring using care as to not lose plunger
or spring. Clean valve internals and plunger. Reassemble in reverse
order and pressurize.
2. Valve will not open:
Action: Check supply to insure presence of electrical power.
Action: Disassemble valve per the instructions above (Item 1) and check for debris interfering with
the movement of the plunger. Clean and reassemble.
Spare Parts
Spare parts are available. Consult your supplier for price
and availability.
