CALIFORNIA PROPOSITION 65 WARNING:
This product and related accessories
contain chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
INSTALLATION:
To ensure accuracy of measurement, the CBV should be
located at least five pipe diameters downstream from any fitting
and at least ten pipe diameters downstream from a pump. Two
pipe diameters downstream from the CBV should be free of any
fitting (as illustrated in Fig. 1).
CBV valves must be installed with flow in the direction of the
arrow on the valve body. Easy access to the probe metering
ports (P.M.P’s) and handwheel must be provided.
CBV valves can be installed in horizontal or vertical piping.
The metering ports should never be installed below the
pipe (pointing down), as this will allow system sediment to
accumulate in the ports. (Illustrated below for horizontal piping
in Fig. 2.)
CBV angle-style valves are designed to replace piping elbows.
Metering ports and body plugs may be interchanged for
improved accessibility.
BOLT TIGHTENING:
Tighten all bolts evenly in standard star pattern. When used
with a “raised face” flange, there will be a gap between the
faces on the outer flange diameters.
CONVERSION (STRAIGHT TO ANGLE):
1. Open the valve one complete turn.
2. Remove the body bolts from the valve body.
 3.Rotateone-halfofthevalvebody180˚,makingsuretheseat
andO-ringstayinpositionanddonotgetnickedorcut.
4. Replace the body bolts and tighten evenly.
5. With no arrows visible, the inner scale set at 0 on the
indicator line aligned with the 0 on the outer scale, the valve
is closed. Refer to Fig. 3.
6. Figure 4 shows a valve setting of 2.0, indicating that the
valve is partially open.
7.With all arrows visible, the inner scale set at 6 and the
indicator line aligned with outer scale 0, the valve setting is
6.0 and the valve is fully open. Refer to Fig. 5.
OPERATION:
The valve operates from closed (Fig. 3) to fully open by a
counterclockwise rotation of the red handwheel. Use five (5)
380˚ turns for the 2-1/2" and 3" valves, six (6) turns for the
4", 5", and 6" valves, 12 turns for the 8" and 10" valves and
14turnsforthe 12"valve. Twoscales indicatethe positionof
the valve.
Inner Scale (Figs. 4 and 5) – This sleeve has a vertical arrowed
scale which indicates the number of full turns the valve has
been opened.
Outer Scale (Figs. 4 and 5) – This scale is a micrometer-type
scale marked 0–9 at the tapered base of the handwheel. Each
gives 1/10th indications for each 360˚ turn of opening against
the indicator line of the inner scale. Connect meter quick-
disconnect hoses to metering ports as follows:
• Remove protective cap from metering ports.
 •Insertandlockthemeterprobeintothemeteringports.

The hose with the red fitting is upstream; the hose with the blue
fitting is downstream.
The probe should not be left inserted into the fitting for
prolongedperiodsoftime,suchasovernight,asleakage
of the P.M.P may occur when the probe is removed.
The locking nut on the probe is designed to hold it in the
P.M.P.whentakingreadingsinsystemshavingahighworking
pressure. As sealing is accomplished internally on the probe
stem,itisonlynecessarytotightenthelockingnutfinger-tight.
Overtightening may cause damage to the P.M.P. or locking
nut threads.
Safety glasses should be used.
Beforetaking aflow measurementreading,setthevalvetoits
fully open (4.0) or at a preset position. Read the pressure drop
across the valve. Curves are in the Aurora catalog.
MEMORY SETTING – 2-1/2"– 6" VALVES (FIG. 6):
After the valve has been adjusted to its balance setpoint and
without moving the handwheel, remove the retaining bolt from
theendofthehandwheelusinga1/4"Allenwrench.
Carefully remove the handwheel and turn indicator sleeve
assembly, leaving the valve at its balance setpoint.
Turn the plastic memory stop (clockwise) down until it stops.
Finger-tight pressure is sufficient. Do not overtighten.
Holding the memory stops in position, turn the lock collar
(clockwise) down until it stops against the valve bonnet. The
memory has now been set.
With the handwheel/turn indicator sleeve assembly still at its
balance setpoint indication, reinstall them on the valve stem and
holdinplacewiththe1/4"retainingbolt.
Care must be taken not to rotate the valve stem or
change the handwheel/indicator setting while setting
the memory.
REPOSITIONING HANDWHEEL – 2-1/2"– 6" VALVES:
Thehandwheelcanberemovedandrepositionedinanyofsix
positions around the stem.
a. Close valve fully.
b. Remove handwheel-retaining bolt.
c. Remove handwheel and turn indicator sleeve by grasping
the handwheel and pulling away from the valve body
along the stem.
d. Select a new position for easy reading and with the sleeve
and handwheel held together in the closed position (0.0),
pushthembackoverthebonnetheadandvalvestem.
e. Replace handwheel-retaining bolt.
f. Open valve.
If handwheel is removed for any reason, it is important to
first close the valve and then replace the handwheel
per d. and e. above.
REPACKING CBV UNDER FULL SYSTEM PRESSURE –
2-1/2"– 6" VALVES:
1. Open valve fully to its memory setting and, on a piece of
paper, record the valve setting.
 2.Remove the handwheel/indicator sleeve assembly as
instructed in the first and second paragraphs under “Memory
Setting.”

seats against the top of the memory stop.
 4.Remove the memory stop/lock collar assembly by turning
theplasticmemorystopcounterclockwise.
 5.UsingthehandwheelWITH THE INDICATOR SLEEVE
REMOVED,turnthevalvestemcounterclockwiseuntilthe
valve is fully open and will not turn any further (45 ft. lbs.).
Asteponthevalveplughasnowbeenback-seatedagainst
the upper portion of the valve body (metal-to-metal).
6. The valve bonnet may now be removed. There may be slight
leakage,asthemetal-to-metalbackseatingdoesnotprovide
a drip-tight seal.
 7.Cleanexposedportionofvalvestem(donotscratch).
 8.RemoveandreplacetheO-ringandgasket.
