General Description

The Model BFV-N Grooved End Butterfly Valves  are indicating 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 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
first two revolutions of the handwheel.
