DELUGE VALVE, EXTERNAL RESETTING
MODEL F470 MULTIMATIC
®
— 4 and 6 INCH (100 and 150 mm)
GENERAL DESCRIPTION
The 4 and 6 inch (100 and 150 mm),
Model F470 External Resetting Multi-
matic Deluge Valves are differential
latch type valves designed for fire pro-
tection system service. They are used
as “automatic water control valves” in
deluge, preaction, and special types of
fire protection systems such as foam-
water and double interlock. The F470
Valves also provide for actuation of fire
alarms upon system operation.
The external resetting feature of the
F470 Valve provides for easy resetting
of a deluge or preaction system, with-
out having to open a valve handhole
cover to manually reposition a clapper
and latch mechanism. Simply depress-
ing a plunger at the left side of the
F470 Valve allows the clapper and
latch to reset.
Operation of an F470 Valve is provided
by an actuation (detection) system that
is separate from the normally dry sys-
tem piping. Trim configuration options
for automatic operation of the F470
include wet pilot actuation, dry pilot
actuation, and electric actuation. Trim
arrangements also provide for local
emergency (manual) release of the
F470 Valves.
