CLA-VAL 136-AU User manual

Model 136-AU Battery-Operated Programmable
Control Valve is ideal for automating distribution
system flushing applications. The valve is
installed in distribution system locations that
require a regular flushing schedule to maintain
system water quality within disinfection and
health standard limits. The valve vents a small
quantity of water for a short time on a regular
schedule to create desired water turnover.
Other Model 136-AU applications requiring
remote, stand alone valve opening and closing
on a predetermined schedule include night-time
tank filling, service line limiting time of use, auto-
matic line strainer flushing, etc.

•Easy Installation and Maintenance
The Cla-Val Model 136-AU Battery-Operated Programmable Control Valve
provides on-off control of water flow according to a program sequence
without any outside power or remote control device required. The completely
self-contained 136-AU consists of a Hytrol main valve and 97VC-4
Programmable Solenoid Controller Unit that alternately applies pressure to
or relieves pressure from the diaphragm chamber of the main valve to
close or open it. An adjustable speed control is supplied for closing rate
adjustment and surge control.
The 97VC-4 Programmable Solenoid Controller Unit contains controller with
display, solenoid, actuator, and battery. The 97VC-4 uses the latest technolo-
gy for easy and flexible programming of desired opening and closing sched-
ule according to time of day, day of week, and month. The controller clock
includes leap year. With normal use, the factory installed lithium battery will
operate the 136-AU for up to 10 years. Manual override of program is eas-
ily accomplished. It has a LCD display to show clock and programming set-
tings. The 97VC-4 has a waterproof design that is submersible to NEMA 6P
standard.

136-AU PURCHASE SPECIFICATIONS
The Battery-Operated Control Valve shall consist of an on-
off control valve, which opens or closes upon receiving
hydraulic signals from attached programmable controller
that contains an integral latching, battery-powered sole-
noid valve. The control valve shall be diaphragm actuated
and fully guided using an integral bearing in the seat and
cover. The programmable controller shall be waterproof to
NEMA 6P and initiate all on or off operation sequences of
the main control valve by the activation of the latching
solenoid. All electrical power for controller and solenoid
shall be from a single 3.6 Volt Lithium Battery contained in
the controller housing.
Two dials and plus and minus toggle buttons shall be pro-
vided on the top of the controller along with LCD type dis-
play under a removable protective cover and shall allow
easy programming of the controller and valve sequence.
The controller shall allow the user to set the current time,
date, and year.
Six programming choices shall provide valve actuation for
every day of the week, and for true odd/even or 1-30 day
intervals. Valve actuation shall be programmed to begin
on the minute and run one minute to 12 hours in duration.
The controller shall provide a means of manually overriding
the programmed schedule with a timed 10 minute default
ON operation and a dedicated OFF function.
The Battery-Operated Control Valve shall be similar in all
respects to the Model 136-AU as manufactured by Cla-Val
Company, Newport Beach, California.
97VC-4 OPERATION AND PROGRAMMING
The 97VC-4 Programmable Controller uses the latest
technology and will provide many years of reliable service.
Please follow these instructions for programming and gen-
eral operation information on the 97VC-4 and 136-AU.

Turn the Select dial to the YEAR position. Press the + or -
keys to scroll to the correct year. When DATE and YEAR
are selected the day of the week is automatically set. The
97VC-4 is leap year compatible.
CHANGING CLOCK DISPLAY FORMATS
Default TIME display format is 12 hour clock with
Month:Day format. If desired, the display can be changed
to 24 hour and Day:Month format after initial setting.
Rotate Select dial to the TIME or DATE position. Press
the + and - keys at the same time to change the clock for-
mat. If in 12 hour format, the PM indicator will disappear
and the clock will change to 24 hour time and the date dis-
play will change to Day:Month format. Days of the week
will change from SMTWTFS to 1234567 (Sunday = 1).
To change display back to 12 hour clock and Month:Day
format repeat the above steps.
SETTING A VALVE SCHEDULE
The 97VC-4 Controller can be programmed to run 1 to 6
programs per day. This means that you can open and
close the 136-AU valve from 1 to 6 times in a 24 hour peri-
od.
SET TIME SCHEDULE
Begin setting desired valve schedule by starting with
Program 1. Turn Select dial to PROGRAM 1 position.
SET START TIME
Turn the Set dial to START TIME. Press the + or - keys to

when necessary. Remove two screws under control hous-
ing and gently open the unit. Replace the battery.
Carefully replace housing and install the two screws.
PLUNGER CLEANING
If valve fails to operate debris may need to be cleaned from
the 97VC-4 plunger area. By hand, rotate programmer and
plunger assembly clockwise to loosen. Gently remove it
from valve port. Remove any visible debris. To clean the
plunger and plunger tube at the bottom of the 97VC-4, gently
remove the plastic plunger retainer with needle-nosed pliers.
Carefully clean debris from plunger and plunger tube. Avoid
damage when replacing plunger retainer, plunger tube,
plunger, and programmer assembly.
LCD DISPLAY
If LCD display is not working or the battery symbol is
flashing, the battery must be replaced.
