General
Description
The TYCO DV-5a Automatic Water
Control Valve Deluge Electric Actua-
tion are diaphragm type valves that
can be used in deluge fire protection
systems. When properly trimmed, the
double seat design of the DV-5
a Valve
also provides actuation of fire alarms
upon system operation.
The diaphragm style design of the
DV-5
a Valve allows external resetting,
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
a features internal and exter-
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
a in cor-
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
The DV-5
a Deluge Electric Actuation
Valve is offered with the DV-5
a Valve
and separately ordered semi-assem-
bled trim as shown in Figure 5.
The DV-5
a Deluge Electric Actua-
tion Valve is offered with or without a
System Main Control Valve.
