General
Description
The TYCO Model BFV-N Wafer Style
Buttery Valves (Ref. Figure 1) are indi-
cating type valves designed for use in
re protection systems where a visual
indication is required as to whether the
valve is open or closed. They are used,
for example, as system, sectional, and
pump water control valves. They are
suitable for installation between ANSI
Class 125 or 150 anges without the
need for ange gaskets.
For applications requiring supervision
of the open position of the valve, the
Gear Operators for the Model BFV-N
Butterfly Valves are provided with
two sets of factory installed internal
switches each having SPDT contacts.
The supervisory switches transfer their
electrical contacts when there is move-
ment from the valve’s normal open posi-
tion during the rst two revolutions of
the handwheel.
NOTICE
The TYCO Model BFV-N Wafer Style
Butterfly Valves described herein must
be installed and maintained in compli-
ance with this document, as well as with
the applicable standards of the National
Fire Protection Association, in addition
to the standards of any other authori-
ties having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for maintaining
their fire protection system and devices
in proper operating condition. Con-
tact the installing contractor or product
manufacturer with any questions.

Friction Loss
The approximate friction loss, based
on the Hazen Williams formula and
expressed in equivalent length of pipe
with C= 120, is as follows. Unless oth-
erwise indicated, the data is based on
friction loss information collected at a
typical ow rate of 15 feet per second.
• 4.4 feet of 2 inch Sch. 40 pipe for
the 2 inch valve.
• 6.2 feet of 2-1/2 inch Sch. 40 pipe
for the 2-1/2 inch valve.
• 7.6 feet of 3 inch Sch. 40 pipe for
the 3 inch valve.
• 9.2 feet of 4 inch Sch. 40 pipe for
the 4 inch valve.
• 9.0 feet* of 5 inch Sch. 40 pipe for
the 5 inch valve.
• 8.2 feet of 6 inch Sch. 40 pipe for
the 6 inch valve.
• 12.7 feet* of 8 inch Sch. 30 pipe for
the 8 inch valve.
• 20.1 feet* of 10 inch Sch. 30 pipe for
the 10 inch valve.
• 22.3 feet* of 12 inch Sch. 30 pipe for
the 12 inch valve.

Installation
The TYCO Model BFV-N Wafer Style
Buttery Valves may be installed with
flow in either direction and can be
positioned either horizontally or verti-
cally. They are designed for installation
between the faces of ANSI Class 125
and 150 anges. The Series BFV-N are
self-sealing between mating anges;
therefore, they do not require the use
of additional gaskets.
The Model BFV-N may be installed with
any pressure class or schedule of pipe
or tubing no greater than schedule 40
that is listed or approved for re protec-
tion service and installed in accordance
with the manufacturer’s instructions.
The wafer bodies have locating lugs to
ensure proper centering of the valve
body when ange bolts are installed.
Refer to Figure 1 for bolt diameter. Bolts
and studs must meet the minimum
strength requirements of ASTM A307
(Grade B), and the nuts must meet
the minimum strength requirements of
ASTM A563 (Grade A).
Prior to installation, close the valve.
Spread the anges apart to allow the
valve to slip easily between the anges.
Make sure the pipe ange faces are
clean of any foreign material such as
scale, metal shavings, or welding slag.
Insert the valve between the anges
(without ange gaskets). Do not apply
lubricant to the seat faces as this may

damage the seat material. Be sure to
center the valve and do not damage
the liner. Relax the separation of the
anges, install, and hand-tighten all
ange bolts. Slowly open the valve,
checking for free movement of the disc.
If valve opens freely, leave the valve in
the open position, and using a cross-
draw sequence, tighten all ange bolts
until the valve is metal-to-metal with
both mating anges. Recommended
tightening torques are listed in Table A.
Be certain to keep ange faces as paral-
lel as possible during and after tighten-
ing bolts or studs. After nal tightening,
again check the valve for full opening
and closing.
As applicable, refer to Figure 2 for the
internal switch wiring diagram.
Conduit and electrical connections
are to be made in accordance with the
authority having jurisdiction and/or the
National Electrical Code. With reference
to Figure 2, the supervisory switch is
intended for connection to the supervi-
sory circuit of a re alarm control panel
in accordance with NFPA 72. The auxil-
iary switch is intended for the unsuper-
vised connection to auxiliary equipment
in accordance with NFPA 70, National
Electric Code.
NOTE: For outdoor applications with
internal supervisory switches, it is rec-
ommended that wiring connections
be made at a temperature above 15°F
(-9°C), in order to insure sufficient flex-
ibility of the wire lead insulation.
Stop Adjustment Procedure
The gear operator’s OPEN and SHUT
position have been factory set. The
following procedure should be used if
slight adjustments are needed. Refer to
Figure 3.
Step 1. Turn the Handwheel until the
valve is fully closed.
Step 2. Remove the two Lock Screws
(A) from the gear operator body.
Step 3. Turn the Shut Stop Screw (B)
clockwise until snug.
Step 4. Turn the Handwheel until the
valve is fully open.
Step 5. Turn the Open Stop Screw (C)
clockwise until snug.
Step 6. Close the valve by turning the
Handwheel until the valve is fully in
the closed position. Ensure the disc
has returned to the fully closed posi-
tion and the disc is centered in the seat
area. Readjust the Shut Stop Screw if
necessary.
Step 7. Replace the two Lock Screws
(A) into the gear operator body, locking
the stops into position.
Care and
Maintenance
The TYCO Model BFV-N Wafer Style
Buttery Valves must be maintained
and serviced in accordance with this
section.
Before closing a re protection system
control valve for maintenance or inspec-
tion work on either the valve or re
protection system which it controls, per-
mission to shut down the affected re
protection systems must be obtained
from the proper authorities and all per-
sonnel who may be affected by this
decision must be notied.
The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in accordance with the applicable stan-
dards of the National Fire Protection
Association (e.g., NFPA 25), in addi-
tion to the standards of any authority
having jurisdiction. Contact the install-
ing contractor or product manufacturer
with any questions. Any impairment
must be immediately corrected.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualied inspec-
tion service.
