General
Description
The 2-1/2 inch (DN65), Model DV-3
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-3
Valve also provides for actuation of fire
alarms upon system operation.
The automatic resetting feature of the
DV-3 provides for easy, external reset-
ting, without having to open a valve
handhole cover to manually reposition
a clapper and latch mechanism.
Operation of a DV-3 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 DV-3
include wet pilot actuation, dry pilot
actuation, and electric actuation. Trim
arrangements also provide for local
emergency (manual) release of the
DV-3 Valves.
The compact and easily installed trim
arrangements have been designed so
that the DV-3 Valve may be installed
“flow left” or “flow right”
The Model DV-3 Deluge Valve is a
redesignation for the Gem Model
F445.
WARNING
The Model DV-3 Deluge Valve de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
tection Association, in addition to the
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the integrity of these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or manufac-
turer should be contacted relative to
any questions.
