Tyco BFV-N Manual

Model BFV-N Butterfly Valve
Grooved End
General
Description
The Model BFV-N Grooved End But-
terfly Valves (Ref. Figure 1) are indi-
cating type valves designed for use in
fire 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 have
cut groove inlet and outlet connections
that are suitable for use with grooved
end pipe couplings that are listed and
approved for fire protection systems.
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 inter-
nal switches each having SPDT con-
tacts (Ref. Figure 3). The supervisory
switches transfer their electrical con-
tacts when there is movement from the
valve's normal open position during the
first two revolutions of the handwheel.
NOTICE
The Model BFV-N Grooved End But-
terfly 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 authori-
ties having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
