ELECTRONIC DRAIN VALVE Model EDV-115-PA

(1/2" VALVE, LARGE ORIFICE)

PRODUCT PURPOSE & FUNCTION:

V an Air's model EDV-1 15-PA series drain valve is designed to remove accumulated fl uids from compressed air & gas process-

ing equipment. With variable open time (1-60 seconds) and valve closed time (1-60 minutes), users can easily adjust the valve to drain
the required amount of accumulated fl uids. Power on and valve open status lights, as well as a built-in override/test function, give quick
verifi cation of valve operation.

WARNING

• READ INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS DRAIN VALVE.

• DO NOT OPERATE LEAKING OR DAMAGED VALVES. REMOVE THEM FROM SERVICE IMMEDIATELY.

• DO NOT OPERATE VALVE ABOVE MAXIMUM OPERATING PRESSURE AND/OR MAXIMUM TEMPERATURE.

• MAKE SURE NEMA RATING OF VALVE IS COMPATIBLE WITH THE INSTALLATION ENVIRONMENT. FAILURE TO DO
SO MAY RESULT IN SERIOUS PERSONAL INJURY AND/OR DAMAGE TO THE UNIT.

• WHEN INSTALLING THIS UNIT, COMPLY WITH THE NATIONAL ELECTRICAL CODE AND ALL APPLICABLE
FEDERAL, STATE AND LOCAL CODES.

• DRAIN SOLUTION MAY CONTAIN LUBRICANTS AND/OR HAZARDOUS MATERIALS. BE SURE TO COMPLY WITH
ALL APPLICABLE REGULATIONS CONCERNING THEIR DISPOSAL.

• NOT FOR USE ON SINGLE TOWER (DELIQUESCENT) DRYERS OR WITH CORROSIVE LIQUIDS.

INSTALLATION

1.

Relieve and lock out all pressure from drain line.

2.

Clean existing drain line of any pipe scale, weld spatter or
accumulated debris.

BALL VALVE

Install a tee onto the drain line. (Reference Figure 2).

Y-STRAINER

SOURCE

This valve will allow the system to be drained during EDV­115-PA servicing.

5.

On the horizontal tee outlet, install an isolation ball valve,
union and y-strainer. The y-strainer will prevent pipe scale,
weld spatter or accumulated debris from hindering the proper
function of the EDV-115-PA drain valve.

6.

Check EDV-115-PA valve body for fl ow direction arrows and
connect the valve in accordance with the arrows. (Note: To
ensure optimum performance, install EDV-115-PA drain valve
in a horizontal position.)

CAUTION

IF THE EDV-1 15-PA IS INSTALLED BACKW ARDS, IT WILL
NOT WORK.

7.

Close the manual and isolation ball valves.

8.

Adjust timer knobs to desired settings (Reference Timer

Adjustment Section).

9.

Wire or plug the valve into an appropriate grounded power
supply. The "POWER ON" light should now be illuminated.

10.

Open the isolation ball valve. Your EDV-115-PA drain valve is
now ready for operation.

TEST FUNCTION

To verify valve operation, or to manually discharge fl uid,
turn the "CLOSED TIME" knob counter clockwise until it stops in
the area labeled "TEST". The valve will open for the set "OPEN
TIME". After the valve closes, it will automatically repeat the test in
2 seconds unless the "CLOSED TIME" knob is reset to its regular
position.

REQUIRED MAINTENANCE

The EDV-1 15-P A drain valve must be cleaned periodically
to prevent malfunctions. In general, the time between cleanings will
vary depending on the discharge medium and operating conditions.
Leakage, sluggish operation and/or excessive noise (hissing) are
clear indications that the valve should be serviced. (NOTE: Noise
associated with air exhausting during valve open time is normal.)

WARNING

NEVER REMOVE OR REPLACE ANY PART ON EDV-115­P A OR THE STRAINER WHILE THEY ARE PRESSURIZED.
CLOSE BALL VALVE AND DEPRESSURIZE DRAIN LINE
USING EDV-115-PA TEST FUNCTION.
