General
Description
The TYCO DV-5 Automatic Water
a
Control Valve Deluge Wet Pilot Actu-
ation is a diaphragm type valve that
can be used in deluge fire protection
systems. When properly trimmed, the
double seat design of the DV-5
also provides actuation of fire alarms
upon system operation.
The diaphragm style design of the
DV-5 Valve allows external resetting,
a
providing 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 features internal and exter-
a
nal coating of the valve to provide
corrosion resistance. The external cor-
rosion resistance of the epoxy coating
permits the use of the DV-5
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.

a
Valve is offered with the DV-5

bled trim as shown in Figure 5 for ease

a
tion Valve is offered with or without a
