General
Description
The DV-5 Deluge Valves are diaphragm
type valves used as “automatic water
control valves” in deluge fire protection
systems. When properly trimmed, the
DV-5 Valves are also able to provide
actuation of fire alarms upon system
operation.
The diaphragm style design of the DV-5
Valve allows external resetting, pro-
viding for easy resetting of a deluge
system without having to open a valve
handhole cover to manually reposition
a clapper and/or latch mechanism.
Simply re-pressurizing the diaphragm
chamber resets the valve.
The DV-5 also features internal and
external coating of the valve to provide
corrosion resistance. The external
corrosion resistance of the RILSAN
coating permits the use of the DV-5 in
corrosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
NOTICE
The DV-5 Deluge Valves described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the Approval agency, in
addition to the standards of any other
authorities 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.
