General
Description
The 2-1/2 inch (DN65), Model DV-3HP
Automatic Resetting Deluge Valve is a
quick opening, hydraulically operated
differential type valve designed for fire
protection system service. It is used as
an "automatic water control valve" in
deluge, preaction, and special types of
fire protection systems such as foam-
water and double interlock. The DV-
3HP Valve also provides for actuation
of fire alarms upon system operation.
. . . 12
The automatic resetting feature of the
DV-3HP provides for easy, external
resetting, without having to open a
valve handhole cover to manually re-
position a clapper and latch mecha-
nism.
Operation of a DV-3HP Valve is pro-
vided by an actuation (detection) sys-
tem that is separate from the normally
dry system piping. Trim configuration
options for automatic operation of the
DV-3HP include wet pilot actuation,
dry pilot actuation, and electric actua-
tion. Trim arrangements also provide
for local emergency (manual) release
of the DV-3HP Valves.
The compact and easily installed trim
arrangements have been designed so
that the DV-3HP Valve may be in-
stalled "flow left" or "flow right"
The Model DV-3HP Deluge Valve is a
redesignation for the Gem Model
F446.
