Valve Description
The Center Line Resilient Seat Butterfly Valve (RSBFV) is
designed for use in ANSI Class 150 piping systems and is
available in both Wafer and Lug style body designs. The
standard valve size range available is as follows:
• Series 200 200 psi Standard BFV 2" to 12"
150 psi Standard BFV 14" to 36"
• Series 205 200 psi Short Neck BFV 2" to 12"
• Series 225 285 psi BFV 2" to 24"
• Series 400 Damper Style BFV 2" to 12"
• Series 800 Check Valve 2" to 24"
Center Line Series 225 Butterfly Valve are also available
with an ANSI Class 300 bolt pattern for Lug bodies of sizes
2" through 12".
Valve Design Features
• The unique Center Line seat and disc design insures
positivevalvesealingwhilemaintaininglowseatingtorque.
• All Center Line Butterfly Valve discs are precision ma-
chinedtoahalfballprofile,providingaprecisedisctoseat
relationship.
• Center Line's cartridge style seat incorporates an elas-
tomer bonded to a phenolic stabilizing ring, eliminating
elastomermovementandreducingseattearingorfatigu-
ing due to bunching.
• Center Line's basic three bushing design completely
isolates the valve shaft from the body, resulting in in-
creased control of the valve disc, lower valve seating
torque, and longer valve life.
• TheCenter Line cartridge seat has a much smallermass
of elastomer than traditional boot seat designs, limiting
seat swell and the accompaning variations in seating
torque.
Flange and Pipe Schedule Compatibility
TheCenterLineRSBFVisdesignedtofitbetweenstandard
piping flanges as follows:
• ANSI 125 Cast Iron Flanges (All Sizes)
• ANSI 150 Steel Flanges, Schedule 40 (All Sizes)
• ANSI 150 Steel Flanges, Schedule 80 (2" to 10")
• ANSI 300SteelFlanges,Schedule40(Series225Lug,

Product Identification
EachCenter Line valve has an identification tag attached to
the valve body. Information on this tag includes the valve

When lifting the valve, take care to avoid damage to the
flange faces, disc sealing edge, or operator.
Ifthevalveistobestoredbeforebeinginstalled,itshould
be protected from harsh environmental conditions.
Store the valve with the disc in the “almost closed”
position to protect the sealing edge and the seat.
Keepthevalveinacleanlocation,awayfromdirt,debris
and corrosive materials.
Keep the valve in a dry area with the flanges protected
and on a suitable skid or pallet.
Keepthe valve in a cool location if possible, out of direct
sunlight.
Opening Rotation
The Center Line valve disc can rotate 360°without damag-
ing the valve or elastomer seat. The valve is designed to
open with either clockwise or counterclockwise rotation of
the shaft.
Valve Ratings
Center Line valves are intended for use at the pressure
indicated on the nameplate attached to each individual
valve.Check thevalveoperating temperature andpressure
rating before proceeding with installation.

INSTALLATION RECOMMENDATIONS
SECTION 2
Valve and Flange Preparation
If the valve and mating pipe are properly prepared for
installation, future problems can be avoided. All valve seat
and pipe flange faces should be free of dirt, grit, dents, or
surface irregularities which may disrupt flange sealing and
cause external leakage. The valve disc sealing surface
should also be inspected to eliminate any dirt or foreign
material that will adversely affect the operation of the valve.
Installation Position
To prevent damage to the disc and seat during installation,
the valve disc should be slightly open but not extending
beyond the valve liner face. Positioning the disc in this
“almost closed” position will reduce seat interference and
initial torque build-up during valve installation.
Ingeneral,itispreferabletoinstallRSBFV'swiththe shaft
in a horizontal orientation. In this position, shaft and disc
weights are evenly distributed, minimizing seat wear.
Additionally, any foreign matter which may accumulate at
the bottom of the disc and shaft is effectively removed
each time the valve is opened.
Center Line butterfly valves are designed to operate be-
tweentwoflanges.If the valve installation calls for theuse
of one pipe flange only, a Lug style valve with Dead End
Service feature must be used.
Disc Clearances
Prior to installing the valve, it is important to make sure the
IDofthepipeandthepipeflangesare largeenoughtoallow
thediscedgetoswingintotheopeningwithoutinterference.
Damagetothediscedgecanseverlyaffecttheperformance
of the valve. Flange and pipe schedule compatibility for
Center Line valves is shown in Section 1 of this manual.

Unpacking and Storage Instructions
Installation Tools
The only tool required in the installation of a Center Line
RSBFV is a wrench suitable for tightening the flange bolts
and/ornutsrequiredtosecurethevalvein-line.A hoistmay
berequiredtohelpmanipulatevalves10"andlarger.Smaller
sized valves can usually be installed by hand. Temporary
pipe supports may be used to keep mating flange faces
parallel in order to aid in valve installation.
Required Bolting
ThetableoutlinedonPage7isfurnishedtoprovideinforma-
tion regarding the size, type, and quantity of bolting recom-
mended for the installation of Center Line RSBFV's. This
table is intended for use as a planning and procurement
guide. All recommendations are based on pipe flanges in
accordance with ANSI 125/150 specifications. Flange bolt-
ing is not included with the valve shipment.

Inspect the valve to be certain the waterway is free from
dirtandforeignmatter.Becertaintheadjoiningpipelineis

or welding slag that could damage the seat and disc

Any actuator should be mounted on the valve prior to
installation to facilitate proper alignment of the disc in the

ating pressure to be sure they are correct for the applica-
tion.

Personal injury or property damage
may result if the valve is installed
where service conditions could ex-
ceed the valve ratings.
WARNING!
Position the connecting pipe flanges in the line to insure
proper alignment prior to valve installation. Spread the pipe
flanges apart enough to allow the valve body to be located
between the flanges without actually contacting the flange
surfaces(SeeFigure1.)Exerciseparticularcareinhandling
thevalvesoastopreventpossibledamagetothediscorseat
faces.
Valve Installation Procedure
For Lug style valves:
a. Place the valve between the flanges.
b. Install all bolts between the valve and the mating
flanges. Hand tighten bolts as necessary.
For Check Valves:
a. Note the opening direction of the disc for proper
valve orientation.
b. Place the valve between the flanges using the four
(4) alignment holes provided.
c. Install the remaining flange bolts, shifting the valve
asnecessarytopermittheboltstopassbythevalve
body. Hand tighten bolts as necessary.

Beforecompletingthe tighteningofanybolts,thevalve
should be centered between the flanges and then
carefully opened and closed to insure free, unob-
structed disc movement (See Figure 2.)
Using the sequence shown in Figure 3, tighten the
flange bolts evenly to assure uniform compression.
If an actuator is to be used, air hoses or electricity
should be connected to the unit as specified by the
actuator manufacturer.
Cycle the valve to the fully open position, then back to
the fully closed position, checking the actuator travel
stop settings for proper disc alignment. The valve
should be operated to assure that no binding is taking
place.
The valve is now ready for operation.
Remember: Install the valve with the disc in
the “ALMOST CLOSED” position.
Do not use any flange gaskets.
Correct
Disc positioned in the
almost closed position.
Pipe flange spread allows
sufficient room for valve.
Incorrect
Disc opened beyond valve
body face. Pipe flanges not
spread sufficiently.
Figure 1-Initial Installation ofValve

a. Place the valve between the flanges.
b. Loosely install the two upper and lower flange bolts
that pass through the body alignment holes.
c. Installthe remaining flange bolts,shiftingthe valve as
necessary to permit the bolts to pass by the valve
body. Hand tighten all bolts as necessary.
