General
Description
The TYCO Model BFV-N Wafer Style
Buttery Valves (Ref. Figure 1) are indicating 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 movement from the valve’s normal open position 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 compliance with this document, as well as with
the applicable standards of the National
Fire Protection Association, in addition
to the standards of any other authorities 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. Contact the installing contractor or product
manufacturer with any questions.

MODEL BF V-N WAFER STYLE BUTTERFLY VALVE
Installation
The TYCO Model BFV-N Wafer Style
Buttery Valves may be installed with
flow in either direction and can be
positioned either horizontally or vertically. 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 protection service and installed in accordance
with the manufacturer’s instructions.

NOMINAL DIMENSIONS
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 crossdraw 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 parallel as possible during and after tightening 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 supervisory circuit of a re alarm control panel
in accordance with NFPA 72. The auxiliary switch is intended for the unsupervised connection to auxiliary equipment
in accordance with NFPA 70, National
Electric Code.
NOTE: For outdoor applications with
internal supervisory switches, it is recommended that wiring connections
be made at a temperature above 15°F
(-9°C), in order to insure sufficient flexibility 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

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 position 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
Buttery Valves must be maintained
and serviced in accordance with this
section.
Before closing a re protection system
control valve for maintenance or inspection work on either the valve or re
protection system which it controls, permission to shut down the affected re
protection systems must be obtained
from the proper authorities and all personnel who may be affected by this
decision must be notied.
The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in accordance with the applicable standards of the National Fire Protection
