INTRODUCTION
SECTION 1
Valve Description
The Center Line Resilient Seat Butterfly Valve (RSBFV) is
designed for use in ASME 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 225
285 psi BFV
2" to 24"
• Series 250
285 psi BFV (SS & CS) 2" to 24"
• Series 300
Two-piece Stem
2" to 12"
• Series 800
Check Valve
2" to 24"
Center Line Series 225 Butterfly Valve are also available
with an ASME Class 300 bolt pattern for Lug bodies of sizes
2" through 12".
Valve Design Features
• The unique Center Line seat and disc design insures
positive valve sealing while maintaining low seating torque.
• All Center Line Butterfly Valve discs are precision machined to a half ball profile, providing a precise disc to seat
relationship.
• Center Line's cartridge style seat incorporates an elastomer bonded to a phenolic stabilizing ring, eliminating
elastomer movement and reducing seat tearing or fatiguing due to bunching.
• Center Line's basic three bushing design completely
isolates the valve shaft from the body, resulting in increased control of the valve disc, lower valve seating
torque, and longer valve life.
• The Center Line cartridge seat has a much smaller mass
of elastomer than traditional boot seat designs, limiting
seat swell and the accompaning variations in seating
torque.
Gasket Compatibility
In the Center Line butterfly valve and check valve design, the
elastomer seat extends beyond the valve face and provides
a leakproof seal between the valve and the mating pipe
flange faces. Gaskets are not needed and should not be
used when the valve is installed between standard weld
neck or slip-on type flanges.
Operating Pressures
All Center Line Series 200 and 205 Butterfly Valves are rated
at 200 psi bubble tight shut-off for sizes 2" to 12" and 150 psi
bubble tight shut-off for sizes 14" and larger. Center Line
Series 225 Butterfly Valves are rated for bubble tight shutoff at 285 psi, while Series 400 Damper Valves which are not
designed for bubble tight shut-off have a body working
pressure of 200 psi. Center Line Series 800 Check Valves
are rated at a minimum pressure differential of 25 psi and a
maximum pressure differential of 150 psi for bubble tight
shut-off.
Product Identification
Each Center Line valve has an identification tag attached to
the valve body. Information on this tag includes the valve
Series Number, materials of construction for the Body, Disc,
and Seat, and the valve Pressure Rating.
Flange and Pipe Schedule Compatibility
The Center Line RSBFV is designed to fit between standard
piping flanges as follows:
• ASME 125 Cast Iron Flanges (All Sizes)
• ASME 150 Steel Flanges, Schedule 40 (All Sizes)
• ASME 150 Steel Flanges, Schedule 80 (2" to 10")
• ASME 300 Steel Flanges, Schedule 40 (Series 225 Lug,
2" to 12" only).
When using Schedule 80 piping, special care must be taken
to make sure the valve is centered between the flanges to
prevent damage to the disc edge when opening or closing.

SECTION 2
Valve Ratings
Center Line valves are intended for use at the pressure
indicated on the nameplate attached to each individual
valve. Check the valve operating temperature and pressure
rating before proceeding with installation.
Valve Seat Position
All Center Line butterfly valves are completely bi-directional,
so installation is not dependent on seat orientation. For Center
Line Series 800 Check Valves, every effort should be made for
installation with backflow protection (no flow) into the seat side
of the valve. Bubble-tight shutoff will be achieved in this
orientation with 25 to 150 psi ∆P across the valve.
Disc Clearances
Prior to installing the valve, it is important to make sure the
ID of the pipe and the pipe flanges are large enough to allow
the disc edge to swing into the opening without interference.
Damage to the disc edge can severly affect the performance
of the valve. Flange and pipe schedule compatibility for
Center Line valves is shown in Section 1 of this manual.
Opening Rotation
The Center Line valve disc can rotate 360° without damaging the valve or elastomer seat. The valve is designed to
open with either clockwise or counterclockwise rotation of
the shaft.
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.
In general, it is preferable to install RSBFV's with the 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 between two flanges. If the valve installation calls for the use
of one pipe flange only, a Lug style valve with Dead End
Service feature must be used.
CENTER LINE

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 Tools
The only tool required in the installation of a Center Line
RSBFV is a wrench suitable for tightening the flange bolts
and/or nuts required to secure the valve in-line. A hoist may
be required to help manipulate valves 10" and larger. 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
The table outlined on Page 7 is furnished to provide information regarding the size, type, and quantity of bolting recommended 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 ASME 125/150 specifications. Flange
bolting is not included with the valve shipment.
Unpacking and Storage Instructions
1. Check the packing list against the valve received to
verify that the size, material, and trim are correct.
2. Check to make sure that the valve and operator were not
damaged during shipment.
3. When lifting the valve, take care to avoid damage to the
flange faces, disc sealing edge, or operator.
4. If the valve is to be stored before being installed, it should
be protected from harsh environmental conditions.
5. Store the valve with the disc in the “almost closed”
position to protect the sealing edge and the seat.
6. Keep the valve in a clean location, away from dirt, debris
and corrosive materials.
7. Keep the valve in a dry area with the flanges protected
and on a suitable skid or pallet.
8. Keep the valve in a cool location if possible, out of direct
sunlight.

INSTALLATION RECOMMENDATIONS
Pre-Installation Procedure
1. Remove any protective flange covers from the valve.
2. Inspect the valve to be certain the waterway is free from
dirt and foreign matter. Be certain the adjoining pipeline is
free from any foreign material such as rust and pipe scale
or welding slag that could damage the seat and disc
sealing surfaces.
3. Any actuator should be mounted on the valve prior to
installation to facilitate proper alignment of the disc in the
valve seat.
4. Check the valve identification tag for materials, and operating pressure to be sure they are correct for the application.
WARNING! Personal injury or property damage
may result if the valve is installed
where service conditions could exceed the valve ratings.
5. Check the flange bolts or studs for proper size, threading,
and length.
Valve Installation Procedure
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 (See Figure 1.) Exercise particular care in handling
the valve so as to prevent possible damage to the disc or seat
faces.
1. For Wafer style valves:
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. Install the remaining flange bolts, shifting the valve as
necessary to permit the bolts to pass by the valve
body. Hand tighten all bolts as necessary.
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
as necessary to permit the bolts to pass by the valve
body. Hand tighten bolts as necessary.
2. Before completing the tightening of any bolts, the valve
should be centered between the flanges and then
carefully opened and closed to insure free, unobstructed disc movement (See Figure 2.)
3. Using the sequence shown in Figure 3, tighten the
flange bolts evenly to assure uniform compression.
4. If an actuator is to be used, air hoses or electricity
should be connected to the unit as specified by the
actuator manufacturer.
5. 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.
6. 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.
